abstract = {In light of the increasing vulnerability of citizens against cyberattacks, we conducted three representative surveys with German citizens in 2021 (N=1,093), 2023 (N=1,011), and 2024 (N=1,004) to examine their cyber threat awareness, use of protective security measures, and preferred information channels. While our findings attest large proportions of the German population a high level of cyber threat awareness, many citizens feel inadequately informed about coping with cyberattacks and show little confidence in German security authorities to protect citizens and infrastructures. While age correlated with citizens’ awareness and behavior, we only saw minor temporal differences between datasets. Finally, we provide design and policy implications for enhancing citizens’ awareness of cyber threats and implementing security measures.},

abstract = {Browser cookies, especially those from third parties, pose a threat to individual privacy. While it is possible in principle to control the number of cookies accepted, this choice is often neither usable nor truly informed. To address this issue, this study used semi-structured interviews (N=19) to identify attitudes and user requirements to develop an alternative personalised cookie banner, which was evaluated in an online experiment (N=157). The cookie banner explanations were tailored to the privacy knowledge of three groups of users: low, medium and high. The online experiment measured cookie choices and perceived usability of the cookie banner across three groups: an experimental group that viewed the novel cookie banner with personalisation (personalised privacy assistant), a control group that viewed the novel cookie banner without personalisation (privacy assistant) and a control group that viewed the standard cookie banner provided by the website. The results indicate that the novel cookie banner (with or without personalisation) generally resulted in significantly fewer accepted cookies and increased usability compared to the standard cookie window. In addition, the personalised cookie banner resulted in significantly fewer accepted cookies and higher usability than the non-personalised cookie banner. These results suggest that tailoring cookie banners to users' privacy knowledge can be an effective approach to empowering users to make informed choices and better protect their privacy.},

Nevertheless, their responsibility of monitoring, analyzing, and communicating cyber threats and security vulnerabilities have become increasingly challenging due to the growing volume and varying quality of information disseminated through public and social channels. Based on a design case study conducted from 2021 to 2023, this paper combines three iterations of expert interviews (N=25), design workshops (N=4) and cognitive walkthroughs (N=25) to design an automated, cross-platform and real-time cybersecurity dashboard. By adopting the notion of cyber situational awareness, the study further extracts user requirements and design heuristics for enhanced threat intelligence and mission awareness in CERTs, discussing the aspects of source integration, data management, customizable visualization, relationship awareness, information assessment, software integration, (inter-)organizational collaboration, and communication of stakeholder warnings.},

abstract = {Farm Management Information Systems (FMIS) are an important core component of modern farming companies as they allow, e.g., to document activities, create fertilization plans, and feed digital equipment with required data. Since the entire agricultural sector is an essential component of food production, high standards of resilience should be established in the involved companies. Accordingly, the used software should also be designed with high standards on reliability and crisis capability. Based on a literature review, we found that software for farmers with certain resilience needs is lacking. Thus, we designed and evaluated a new FMIS concept with the user-centered design method. By conducting focus groups (two rounds, total N=57) in 2017 and 2019, we raised specific front-end and back-end requirements of farmers. Based on the requirements, we developed our concept for both front- and back-end in terms of a decentralized and offline-working FMIS. Through the evaluation with practitioners (N=16) of the implemented concept, we derived findings and implications, highlighting the need for privacy, stability, and offline-capability, as well as the UI-requirement to be supportive, e.g., with easy to understand icons and terms.},

abstract = {The use of Open Source Intelligence (OSINT) to monitor and detect cybersecurity threats is gaining popularity among Cybersecurity Emergency or Incident Response Teams (CERTs/CSIRTs). They increasingly use semi-automated OSINT approaches when monitoring cyber threats for public infrastructure services and incident response. Most of the systems use publicly available data, often focusing on social media due to timely data for situational assessment. As indirect and affected stakeholders, the acceptance of OSINT systems by users, as well as the conditions which influence the acceptance, are relevant for the development of OSINT systems for cybersecurity. Therefore, as part of the ethical and social technology assessment, we conducted a survey (N=1,093), in which we asked participants about their acceptance of OSINT systems, their perceived need for open source surveillance, as well as their privacy behavior and concerns. Further, we tested if the awareness of OSINT is an interactive factor that affects other factors. Our results indicate that cyber threat perception and the perceived need for OSINT are positively related to acceptance, while privacy concerns are negatively related. The awareness of OSINT, however, has only shown effects on people with higher privacy concerns. Here, particularly high OSINT awareness and limited privacy concerns were associated with higher OSINT acceptance. Lastly, we provide implications for further research and the use of OSINT systems for cybersecurity by authorities. As OSINT is a framework rather than a single technology, approaches can be selected and combined to adhere to data minimization and anonymization as well as to leverage improvements in privacy-preserving computation and machine learning innovations. Regarding the use of OSINT, the results suggest to favor approaches that provide transparency to users regarding the use of the systems and the data they gather.},

Most participants were willing to adopt passwordless authentication during our in-person user study, but closer analysis shows that participants prioritize usability, security, and availability differently depending on the account type. We identify remaining adoption barriers that prevent FIDO2 from succeeding password authentication, such as missing support for contemporary usage patterns, including account delegation and usage on multiple clients.},

abstract = {Concise instruments to determine privacy personas – typical privacy-related user groups – are not available at present. Consequently, we aimed to identify them on a privacy knowledge–privacy behavior ratio based on a self-developed instrument. To achieve this, we conducted an item analysis (N = 820) and a confirmatory factor analysis (CFA) (N = 656) of data based on an online study with German participants. Starting with 81 items, we reduced those to an eleven-item questionnaire with the two scales privacy knowledge and privacy behavior. A subsequent cluster analysis (N = 656) revealed three distinct user groups: (1) Fundamentalists scoring high in privacy knowledge and behavior, (2) Pragmatists scoring average in privacy knowledge and behavior and (3) Unconcerned scoring low in privacy knowledge and behavior. In a closer inspection of the questionnaire, the CFAs supported the model with a close global fit based on RMSEA in a training and to a lesser extent in a cross-validation sample. Deficient local fit as well as validity and reliability coefficients well below generally accepted thresholds, however, revealed that the questionnaire in its current form cannot be considered a suitable measurement instrument for determining privacy personas. The results are discussed in terms of related persona conceptualizations, the importance of a methodologically sound investigation of corresponding privacy dimensions and our lessons learned.},

This article presents a disaggregated whitebox-based visualisation of critical information as a novel nudge. By segmenting users according to their decision-making and information processing styles, we investigate if the novel nudge is more effective for specific users than a common black-box nudge. Based on existing literature about critical factors in password security, we designed a dynamic radar chart and parallel coordinates as disaggregated visualisations. We evaluated the short-term effectiveness and users' perception of the nudges in a think-aloud prestudy and a representative online evaluation (N=1.012). Our findings suggest that dynamic radar charts present a moderately effective nudge towards stronger passwords regarding short-term efficacy and are appreciated particularly by players of role-playing games.},

that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data
itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and
consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk.
Having insight into the business data of others along the
supply chain provides an advantage in terms of market
position. This is particularly true in agriculture, where
there is already a significant imbalance of power between actors. A multitude of small and medium-sized
farming businesses are opposed by large upstream and
downstream players that drive technological innovation.
Further weakening the market position of farmers could
lead to severe consequences for the entire sector. We
found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other
hand, privacy itself influences adoption of digital tools.
Our study sheds light on the emerging challenges for
farmers and the role of privacy in the process of digitalization in agriculture.},

These migration movements increasingly rely on digital infrastructure, such as mobile internet access and online services, in order to reach their targeted destination countries. Asylum seekers often use smartphones for information and communication purposes. Even though there are many positive aspects in the use of such technologies, researchers have to consider the perceived risks of this specific user group. This work aims at investigating the use of mobile information technologies by asylum seekers during their flight, especially taking privacy into account. Thus, it examines asylum seekers’ digital privacy perceptions and identifies privacy protection behaviors by conducting a qualitative interview study with 14 asylum seekers who applied for asylum in Germany. The results show that asylum seekers are often aware of the various risks deriving from the use of smartphones and ICT, such as surveillance and persecution by state or non-state actors as well as extortion by criminals. Based on this, this work furthermore outlines different strategies used to manage these risks. Since the lack of privacy and trust leads to avoidance behavior, the insights of this study provide valuable information for the design of assistance apps and collaboration platforms, which appropriately address the specific needs for digital privacy in the context of flight, or for the conception of privacy-enhancing technologies helping to achieve this.},

Mistral Large for selecting instances. We
demonstrate that ActiveLLM significantly
enhances the classification performance of
BERT classifiers in few-shot scenarios, outperforming
traditional active learning methods
as well as improving the few-shot learning
methods ADAPET, PERFECT, and Set-

abstract = {In rural areas, where restoring public network infrastructure can take time, an alternative communication channel can be particularly valuable. This study explores the potential of repurposing Long Range Wide Area Networks (LoRaWAN) gateways as multi-hop network nodes to create a digital emergency communication system. Farmers, who are increasingly adopting Low Power Wide Area Networks (LPWANs) and are geographically spread, are identified as key stakeholders for such a system. Using OpenStreetMap data on farm locations, we found that connecting farm communities through LoRa communication is theoretically possible in many areas. Simulations using delay-tolerant network routing protocols confirm the feasibility of this approach under various scenarios. A proof-of-concept implementation demonstrates that small messages can be transmitted successfully using real hardware, validating the concept of a decentralized communication infrastructure based on existing equipment. Additionally, we conducted experiments to measure energy consumption, bandwidth usage, and latency in actual hardware setups. This work contributes to various Sustainable Development Goals by supporting resilient communication infrastructure in underserved areas (SDG 9: Industry, Innovation and Infrastructure), strengthening rural communities that are often the last to recover after emergencies (SDG 10: Reduced Inequalities, SDG 11: Sustainable Cities and Communities), and ultimately helping safeguard food systems through improved agricultural coordination and communication (SDG 2: Zero Hunger).},

abstract = {Ensuring that privacy policies accurately reflect the real-world behavior of software systems is a complex socio-technical challenge. Despite the importance of privacy policies for user trust and regulatory compliance, prior research has paid limited attention to how software developers perceive their own activities in achieving alignment between privacy policies and actual software behavior and which organizational factors they identify as leading to misalignment. This perspective is particularly important because developers’ implementation practices directly shape how software handles personal data. To address this research gap, we conducted 15 semi-structured interviews with software developers directly involved in implementing privacy-relevant functionality. Our findings identify several alignment activities performed by developers and highlight symbolic compliance as an important organizational factor contributing to gaps between documented privacy commitments and actual software behavior. Our study offers implications for researchers investigating privacy challenges in software development and provides valuable insights for organizations and developers seeking to better align privacy policies with actual software behavior.},

This paper proposes a CTI-focused crawler using multi-armed bandit (MAB) and various crawling strategies. It employs SBERT to identify relevant documents while dynamically adapting its crawling path. Our system ThreatCrawl achieves a harvest rate exceeding 25\% and expands its seed by over 300\% while maintaining topical focus. Additionally, the crawler identifies previously unknown but highly relevant overview pages, datasets, and domains.},

abstract = {In conflict-ridden environments, timely and accurate information is critical for those dealing with the dynamic of events. When individuals have to flee, it becomes evident that refugees frequently rely on information and communication technologies (ICT) for information acquisition, travel coordination, and maintaining connections with related parties. Based on 17 interviews, this research explores how Ukrainian refugees, who sought protection in Germany due to the 2022 Russian full-scale invasion, use ICT before, during, and after their flight. By providing empirical findings, the results show in depth how contextual factors, such as infrastructural instability, privacy concerns and an advanced digitalization, interrelate with user behaviors. Analyzing the multifaceted civilian ICT use in the context of war and flight, this exploratory research contributes to the existing research on HCI in migration contexts and connects to several topics of CSCW. By contrasting case specifics, this work highlights what makes Ukraine a special case in this research area. Furthermore, this paper examines both existing and emerging affordances of ICT in the context of flight, and identifies the crucial role of messenger groups for information gathering in all phases of the flight. Lastly, collaborative dimensions of the identified affordances are discussed.},

This paper introduces to the HCI community the concept of cellular island connectivity in isolated areas, promising a seamless transition from normal operation to island operation with local-only cellular connectivity. It presents findings from a survey (N = 857) among adult smartphone users from major German cities regarding their smartphone usage preferences in this model. Results show a shift in app demand, with users favoring general-purpose apps over dedicated crisis apps in specific scenarios. We prioritize smartphone services based on their criticality, distinguishing between apps essential for crisis response and those supporting routines.

abstract = {Digital self-organization and collaboration in crisis are hindered not only by the absence of preparedness of citizens but also because of infrastructure disruptions. While citizens want to operate digitally, as they do outside a crisis event, they are often forced to fall back to analog actions. We conducted a survey with affected citizens (N=404) after the 2021 European floods, in which widespread infrastructure blackouts happened. With this survey, we conduct a contextual analysis of digital needs and actions. We investigate how far these were subject to infrastructure outages, how citizens were prepared, and to what degree they participated in informal neighborhood networks. Results show a massive disruption in all infrastructures, which led many citizens to fall back to analog actions. To cope with this, we suggest enhancing digital resilience by rethinking connectivity and understanding preparedness in a digital manner with the proposal of five requirements for digital self-organization in crisis to consider: (1) Digital collaboration should be preferred over analog workarounds; (2) support resilient communication technologies, including (3) being offline in the design; (4) crisis apps should be convenient and use internet-based communication when available; and (5) think of preparedness of citizens by integrating digital tools and actions.},

abstract = {Computer Security Incident Response Teams (CSIRTs) face increasing challenges processing the growing volume of security-related information. Daily manual analysis of threat reports, security advisories, and vulnerability announcements leads to information overload, contributing to burnout and attrition among security professionals. Clustering such information to cope with the initial information volume and enables security professionals to grasp the current overview of the situation more easily and decide on actions. This work evaluates 196 combinations of clustering algorithms and embedding models across five security-related datasets to identify optimal approaches for automated information consolidation. We demonstrate that clustering can reduce information overload by over 90 \% while maintaining semantic coherence. Our evaluation indicates a minimal need of configuration to successfully cluster information within a reasonable timespan on consumer hardware. The findings suggest that clustering approaches can significantly enhance CSIRT operational efficiency while maintaining analytical integrity. However, complex threat reports require careful parameter tuning to achieve acceptable performance, indicating areas for future optimization (The code is made publicly available at the following URL: https://github.com/PEASEC/reducing-information-overload)},

In this study, we examined 20 popular, free-to-download children's apps in German-speaking regions to assess the prevalence of deceptive design patterns and advertising. Despite platform policies and EU frameworks like the General Data Protection Regulation and the Digital Services Act, every app contained interface manipulations intended to nudge, confuse, or pressure young users, averaging nearly six distinct deceptive patterns per app. Most also displayed high volumes of non-skippable ads, frequently embedded within core gameplay. These findings indicate a systemic failure of existing safeguards and call for stronger regulation, greater platform accountability, and child-centered design standards.},

abstract = {In many applications and websites people use in their everyday life, their privacy and data is threatened, e.g., by script tracking during browsing. Although researchers and companies have developed privacy-enhancing technologies (PETs), they are often difficult to use for lay users. In this paper, we conducted a literature review to classify users into different support personas based on their privacy competence and privacy concern. With developers of PETs in mind, support personas were envisioned to facilitate the customization of software according to the support needs of different users. In order to demonstrate the usefulness of support personas and based on workshop sessions with 15 participants, we designed a browser extension which supports users with the issue of script tracking by providing different user interfaces for different support personas. The following qualitative evaluation with 31 participants showed that the developed UI elements worked as intended for the different support personas. Therefore, we conclude the concept of support personas is useful in the development process of usable applications that enhance the privacy of the users while also educating them and thus potentially increasing their privacy literacy.},

Our lab study (N=45) demonstrates PairSonic's superior usability, automating the tedious verification tasks from previous approaches via an acoustic out-of-band channel. Although participants significantly preferred our system, minimizing user effort surprisingly decreased the perceived security for some users, who associated security with complexity.

abstract = {In Germany, both law enforcement agencies and dedicated reporting centers engage in various activities to counter illegal online hate speech. Due to the high volume of such content and against the background of limited resources, their personnel can be confronted with the issue of information overload. To mitigate this issue, technologies for information filtering, classification, prioritization, and visualization offer great potential. However, domainspecific classification schemes that differentiate subtypes of online hate speech are a prerequisite for the development of such assistive tools. There is a gap in research with regard to an empirically substantiated classification scheme for subtypes of hate speech for the German law enforcement and reporting center domain. Based on a review of relevant computer science publications (N=24) and qualitative interviews with practitioners (N=18), this work investigates practice-relevant subtypes of hate speech and finds that it is primarily differentiated with regard to targeted group affiliations, the conveyance of an immediate security threat, and criminal relevance. It contributes to the state of research with an empirically grounded online hate speech classification scheme for German law enforcement agencies and reporting centers (C1) and five implications for the user-centered design of hate speech classification tools (C2).},

abstract = {In today’s world, cyber-attacks are becoming more frequent and thus proactive protection against them is becoming more important. Cyber Threat Intelligence (CTI) is a possible solution, as it collects threat information in various information sources and derives stakeholder intelligence to protect one’s infrastructure. The current focus of CTI in research is the clear web, but the dark web may contain further information. To further advance protection, this work analyzes the dark web as Open Source Intelligence (OSINT) data source to complement current CTI information. The underlying assumption is that hackers use the dark web to exchange, develop, and share information and assets. This work aims to understand the structure of the dark web and identify the amount of its openly available CTI related information. We conducted a comprehensive literature review for dark web research and CTI. To follow this up we manually investigated and analyzed 65 dark web forum (DWF), 7 single-vendor shops, and 72 dark web marketplace (DWM). We documented the content and relevance of DWFs and DWMs for CTI, as well as challenges during the extraction and provide mitigations. During our investigation we identified IT security relevant information in both DWFs and DWMs, ranging from malware toolboxes to hacking-as-a-service. One of the most present challenges during our manual analysis were necessary interactions to access information and anti-crawling measures, i.e., CAPTCHAs. This analysis showed 88\% of marketplaces and 53\% of forums contained relevant data. Our complementary semi-automated analysis of 1,186,906 onion addresses indicates, that the necessary interaction makes it difficult to see the dark web as an open, but rather treat it as specialized information source, when clear web information does not suffice.},

the wide adaptation of protocols like TLS. However, challenges

such as PGP and secure messengers like Signal, suffer from issues

legally mandated backdoors are rising as the US and EU are propos-
ing new surveillance regulations requiring chat monitoring. We
present a new E2EE solution called Encrypted MultiChannel Com-
munication ( EMC2), based on 𝑛-out-of-𝑛 secret sharing. EMC2 splits
messages into multiple secret shares and sends them through in-
dependent channels. We show that multiple independent channels
exist between users and EMC2 provides E2EE with no single point of
trust, no setup, and is understandable by the general public. Our so-
lution complements existing tools and strengthens the case against
legally enforced backdoors by demonstrating their ineffectiveness.},

abstract = {Internet of Things (IoT) devices have become increasingly important within the smart home domain, making the security of the devices a critical aspect. The majority of IoT devices are black-box systems running closed and pre-installed firmware. This raises concerns about the trustworthiness of these devices, especially considering that some of them are shipped with a microphone or a camera. Remote attestation aims at validating the trustworthiness of these devices by verifying the integrity of the software. However, users cannot validate whether the attestation has actually taken place and has not been manipulated by an attacker, raising the need for HCI research on trust and understandability. We conducted a qualitative study with 35 participants, investigating trust in the attestation process and whether this trust can be improved by additional explanations in the application. We developed an application that allows users to attest a smart speaker using their smartphone over an audio channel to identify the attested device and observe the attestation process. In order to observe the differences between the applications with and without explanations, we performed A/B testing. We discovered that trust increases when additional explanations of the technical process are provided, improving the understanding of the attestation process.},

abstract = {In many scenarios users have to communicate sensitive data with third parties such as doctors, lawyers, insurance companies, social workers or online shops. Handing over personal data is necessary to use those services but the delegation of tasks to increase efficiency still poses the risk that personal data might be leaked. To minimize this risk and further enhance the privacy of users, we propose an interaction concept that uses layered encryption of messages to provide a trade-off between privacy and usability. Users can choose which data is additionally encrypted in an inner layer, say, for the eyes of their doctor only, and which data is available in an outer (encrypted or unencrypted) layer for all staff members. Another benefit is the hiding of sensitive data from package inspection or crawling algorithms over emails, while less critical parts can still be processed by these systems via the partial access. To investigate this concept, we derive relevant use cases for form-based communication over email from a quantitative pre-study with 1011 participants, showing that general practitioners are the most suitable use case. We developed demonstrators for this use case and evaluated them in a qualitative study with 42 participants. Our results show that the possibility of minimizing the propagation of sensitive data through additional encryption is highly appreciated and the usage of form-based communication is a promising approach for the digital transformation.},

abstract = {The field of cybersecurity is evolving fast. Security professionals are in need of intelligence on past, current and - ideally - on upcoming threats, because attacks are becoming more advanced and are increasingly targeting larger and more complex systems. Since the processing and analysis of such large amounts of information cannot be addressed manually, cybersecurity experts rely on machine learning techniques. In the textual domain, pre-trained language models like BERT have proven to be helpful as they provide a good baseline for further fine-tuning. However, due to the domain-knowledge and the many technical terms in cybersecurity, general language models might miss the gist of textual information. For this reason, we create a high-quality dataset and present a language model specifically tailored to the cybersecurity domain which can serve as a basic building block for cybersecurity systems. The model is compared on 15 tasks: Domain-dependent extrinsic tasks for measuring the performance on specific problems, intrinsic tasks for measuring the performance of the internal representations of the model as well as general tasks from the SuperGLUE benchmark. The results of the intrinsic tasks show that our model improves the internal representation space of domain words compared to the other models. The extrinsic, domain-dependent tasks, consisting of sequence tagging and classification, show that the model performs best in cybersecurity scenarios. In addition, we pay special attention to the choice of hyperparameters against catastrophic forgetting, as pre-trained models tend to forget the original knowledge during further training.},

Currently, the most advanced approaches for agriculture are typically referred to as smart farming and agriculture 4.0, which incorporate more precise cultivation with less manual effort.
But such new agriculture technology developments usually lack an assessment about its impact on the sector's resilience and dependencies on other infrastructures.
The research domains of crisis informatics and IT security mostly focuses on other topics, apart from agriculture.
The resilience research in agriculture itself is currently intensifying, however, this line of research focuses more on problems resulting from the climate crisis and social change.
For these reasons it remains unclear, how digitalization impacts the resilience of food production and food safety.
Therefore, it is not well researched which technological developments may lead to undesired effects in the future.
How modern systems should be designed to allow for both, positive impacts on efficiency, and prevention of negative effects in terms of reduced resilience capacities, is also not answered by current literature.
The aim of the present work is to close this research gap at the intersection of agriculture, digitalization, and resilience.
To answer the question to what extent current technologies used by farmers are at risk of failure, the dissertation first presents a snapshot of the resilience state of agricultural companies and the technologies used.
This involves interviews with stakeholders, mainly farmers, as well as surveying security issues of the LoRaWAN protocol, a transmission technology especially useful for agricultural Internet of Things.
Which desires of farmers exist regarding software focusing on aspects of business continuity and secured operations, is another open question.
This dissertation aims to also answer this question with empirical methods, mainly focus groups and usability tests.
Then the rise of Internet of Things in agriculture raises another question, whether such technologies acquired for smart farming could also have benefits for resilience against internet-connection-lost situations.
This question is answered by empirical evaluation of LoRaWAN range characteristics in agricultural landscapes, as well as artifact generation for resilient communication channels on top of LoRaWAN transmission devices.
Several findings are derived from the conducted research:
There is a lack of understanding of how strong the used tools in agriculture depend on ICT, and many tools require a working internet connection.
Moreover, IT employed by agricultural enterprises presents security concerns similar to those encountered in other domains.
Based on these findings, developments, and evaluations of new software approaches are presented:
Derived design criteria and own system designs that allow for modern data-driven business operations, including IoT integration based on LoRaWAN.
The developed solutions show an increase in resilience capacities by enhancing the communication possibilities in crisis situations.
The detected low absorption capacities against communication infrastructure outages shows room for improvement.
To improve agricultural ITs' resilience, software engineers could use the concepts and designs of this dissertation for their product development, like a modular offline-capable farm management storage that allows an exchange of small data in an autarkic manner via commodity LoRaWAN hardware.
But also technology advisors and farmers benefit from the technological analyses and suggestions embedded in this work, like using multiple LoRaWAN gateways with an overlapping coverage to mitigate security vulnerabilities.},

To counter this, we introduce a novel textual adversarial example method that identifies falsely learned word indicators by leveraging explainable AI methods as importance functions on incorrectly predicted instances, thus revealing and understanding the weaknesses of a model. Coupled with adversarial training, this approach guides models to adopt complex decision rules when necessary and simpler ones otherwise, enhancing their robustness. To evaluate the effectiveness of our approach, we conduct a human and a transfer evaluation and propose a novel adversarial training evaluation setting for better robustness assessment. While outperforming current adversarial example and training methods, the results also show our method's potential in facilitating the development of more resilient transformer models by detecting and rectifying biases and patterns in training data, showing baseline improvements of up to 23 percentage points in accuracy on adversarial tasks. The code of our approach is freely available for further exploration and use.},

abstract = {Browser cookies, especially those from third parties, pose a threat to individual privacy. While it is possible in principle to control the number of cookies accepted, this choice is often neither usable nor truly informed. To address this issue, this study used semi-structured interviews (N=19) to identify attitudes and user requirements to develop an alternative personalised cookie banner, which was evaluated in an online experiment (N=157). The cookie banner explanations were tailored to the privacy knowledge of three groups of users: low, medium and high. The online experiment measured cookie choices and perceived usability of the cookie banner across three groups: an experimental group that viewed the novel cookie banner with personalisation (personalised privacy assistant), a control group that viewed the novel cookie banner without personalisation (privacy assistant) and a control group that viewed the standard cookie banner provided by the website. The results indicate that the novel cookie banner (with or without personalisation) generally resulted in significantly fewer accepted cookies and increased usability compared to the standard cookie window. In addition, the personalised cookie banner resulted in significantly fewer accepted cookies and higher usability than the non-personalised cookie banner. These results suggest that tailoring cookie banners to users' privacy knowledge can be an effective approach to empowering users to make informed choices and better protect their privacy.},

abstract = {The ever-increasing number of threats and the existing diversity of information sources pose challenges for Computer Emergency Response Teams (CERTs). To respond to emerging threats, CERTs must gather information in a timely and comprehensive manner. But the volume of sources and information leads to information overload. This paper contributes to the question of how to reduce information overload for CERTs. We propose clustering incoming information as scanning this information is one of the most tiresome, but necessary, manual steps. Based on current studies, we establish conditions for such a framework. Different types of evaluation metrics are used and selected in relation to the framework conditions. Furthermore, different document embeddings and distance measures are evaluated and interpreted in combination with clustering methods. We use three different corpora for the evaluation, a novel ground truth corpus based on threat reports, one security bug report (SBR) corpus, and one with news articles. Our work shows, it is possible to reduce the information overload by up to 84.8\% with homogeneous clusters. A runtime analysis of the clustering methods strengthens the decision of selected clustering methods. The source code and dataset will be made publicly available after acceptance.},

Nevertheless, their responsibility of monitoring, analyzing, and communicating cyber threats and security vulnerabilities have become increasingly challenging due to the growing volume and varying quality of information disseminated through public and social channels. Based on a design case study conducted from 2021 to 2023, this paper combines three iterations of expert interviews (N=25), design workshops (N=4) and cognitive walkthroughs (N=25) to design an automated, cross-platform and real-time cybersecurity dashboard. By adopting the notion of cyber situational awareness, the study further extracts user requirements and design heuristics for enhanced threat intelligence and mission awareness in CERTs, discussing the aspects of source integration, data management, customizable visualization, relationship awareness, information assessment, software integration, (inter-)organizational collaboration, and communication of stakeholder warnings.},

Obtaining user perspectives on digital interventions addressing the need for transparency (e.g., through indicators) is essential. This article offers a thorough examination of the comprehensibility, usefulness, and limitations of an indicator-based intervention from an adolescents’ perspective. This study (𝑁 = 39; aged 13-16 years) comprised two qualitative steps: (1) focus group discussions and (2) think-aloud sessions, where participants
engaged with a smartphone-app for TikTok. The results offer new insights into how video-based indicators can assist adolescents’ assessments. The intervention received positive feedback, especially for its transparency, and could be applicable to new content. This paper sheds light on how adolescents are expected to be experts while also being prone to video-based misinformation, with limited understanding of an intervention’s limitations. By adopting
teenagers’ perspectives, we contribute to HCI research and provide new insights into the chances and limitations of interventions for VSPs.},

One way in which misinformation is spread is through voice messages sent via messenger groups, which enable members to share information on a larger scale. Gaining user perspectives on digital misinformation interventions as countermeasure after detection is crucial. In this paper, we extract potential features of misinformation in voice messages from literature, implement them within a program that automatically processes voice messages, and evaluate their perceived usefulness and comprehensibility as user-centered indicators.We propose 35 features extracted from audio files at the character, word, sentence, audio and creator levels to assist (1) private individuals in conducting credibility assessments, (2) government agencies faced with data overload during crises, and (3) researchers seeking to gather features for automatic detection approaches. We conducted a think-aloud study with laypersons (N = 20) to provide initial insight into how individuals autonomously assess the credibility of voice messages, as well as which automatically extracted features they find to be clear and convincing indicators of misinformation. Our study provides qualitative and quantitative insights into valuable indicators, particularly when they relate directly to the content or its creator, and uncovers challenges in user interface design.},

abstract = {Publicly available information contains valuable information for Cyber Threat Intelligence (CTI). This can be used to prevent attacks that have already taken place on other systems. Ideally, only the initial attack succeeds and all subsequent ones are detected and stopped. But while there are different standards to exchange this information, a lot of it is shared in articles or blog posts in non-standardized ways. Manually scanning through multiple online portals and news pages to discover new threats and extracting them is a time-consuming task. To automize parts of this scanning process, multiple papers propose extractors that use Natural Language Processing (NLP) to extract Indicators of Compromise (IOCs) from documents. However, while this already solves the problem of extracting the information out of documents, the search for these documents is rarely considered. In this paper, a new focused crawler is proposed called ThreatCrawl, which uses Bidirectional Encoder Representations from Transformers (BERT)-based models to classify documents and adapt its crawling path dynamically. While ThreatCrawl has difficulties to classify the specific type of Open Source Intelligence (OSINT) named in texts, e.g., IOC content, it can successfully find relevant documents and modify its path accordingly. It yields harvest rates of up to 52\%, which are, to the best of our knowledge, better than the current state of the art.},

Since the entire agricultural sector is an essential component of food production, high standards of resilience should be established in the involved companies. Accordingly, the used software should also be designed with high standards on reliability and crisis capability. Based on a literature review, we found that software for farmers with certain resilience needs is lacking. Thus, we designed and evaluated a new FMIS concept with the user-centered design method. By conducting focus groups (two rounds, total N=57) in 2017 and 2019, we raised specific front-end and back-end requirements of farmers. Based on the requirements, we developed our concept for both front- and back-end in terms of a decentralized and offline-working FMIS. Through the evaluation with practitioners (N=16) of the implemented concept, we derived findings and implications, highlighting the need for privacy, stability, and offline-capability, as well as the UI-requirement to be supportive, e.g., with easy to understand icons and terms.},

abstract = {The use of Open Source Intelligence (OSINT) to monitor and detect cybersecurity threats is gaining popularity among Cybersecurity Emergency or Incident Response Teams (CERTs/CSIRTs). They increasingly use semi-automated OSINT approaches when monitoring cyber threats for public infrastructure services and incident response. Most of the systems use publicly available data, often focusing on social media due to timely data for situational assessment. As indirect and affected stakeholders, the acceptance of OSINT systems by users, as well as the conditions which influence the acceptance, are relevant for the development of OSINT systems for cybersecurity. Therefore, as part of the ethical and social technology assessment, we conducted a survey (N=1,093), in which we asked participants about their acceptance of OSINT systems, their perceived need for open source surveillance, as well as their privacy behavior and concerns. Further, we tested if the awareness of OSINT is an interactive factor that affects other factors. Our results indicate that cyber threat perception and the perceived need for OSINT are positively related to acceptance, while privacy concerns are negatively related. The awareness of OSINT, however, has only shown effects on people with higher privacy concerns. Here, particularly high OSINT awareness and limited privacy concerns were associated with higher OSINT acceptance. Lastly, we provide implications for further research and the use of OSINT systems for cybersecurity by authorities. As OSINT is a framework rather than a single technology, approaches can be selected and combined to adhere to data minimization and anonymization as well as to leverage improvements in privacy-preserving computation and machine learning innovations. Regarding the use of OSINT, the results suggest to favor approaches that provide transparency to users regarding the use of the systems and the data they gather.},

Especially in crises or threatening situations, privacy may conflict with other values, such as personal safety and health. In other cases, personal or public safety can also be dependent on privacy: the context of flight shows how, for those affected, the value of data protection can increase as a result of an increased threat situation. Thus, when individual sovereignty—the autonomous development of one’s own will—or safety is highly dependent on information flows, people tend to be more protective of their privacy in order to maintain their information sovereignty. But also, the context of agriculture, as part of the critical infrastructure, shows how privacy concerns can affect the adoption of digital tools. With these two examples, flight and migration as well as agriculture, this chapter presents some exemplary results that illustrate the importance of the influence of situational factors on perceived information sovereignty and the evaluation of privacy.},

In this paper, we present SCAtt-man, the first remote attestation scheme that is specifically designed with the user in mind. SCAtt-man deploys software-based attestation to check the integrity of remote devices, allowing users to verify the integrity of IoT devices with their smartphones. The key novelty of SCAtt-man resides in the utilization of user-observable side-channels such as light or sound in the attestation protocol. Our proof-of-concept implementation targets a smart speaker and an attestation protocol that is based on a data-over-sound protocol. Our evaluation demonstrates the effectiveness of toolname against a variety of attacks and its usability based on a user study with 20 participants.},

abstract = {The digitalisation of critical infrastructure has increased the risk of large-scale cyber incidents. In contrast to the management of conventional emergencies by established civil protection organisations involving volunteers in Germany, few response capacities exist for these events. The concept of a volunteer force for cyber security could close this protection gap. However, such involvement also poses practical and ethical challenges. By conducting interviews with computer science students (N = 11), this paper analyses potential volunteers’ attitudes towards ethical implications of a cyber volunteer force, as well as practical aspects that might motivate or hinder their participation. A qualitative
content analysis reveals that students are largely unaware of potential dilemmas connected to vulnerabilities handling and national cybersecurity interests. Ethical guidelines and means of motivating and encouraging potential volunteers
are discussed.},

Most participants were willing to adopt passwordless authentication during our in-person user study, but closer analysis shows that participants prioritize usability, security, and availability differently depending on the account type. We identify remaining adoption barriers that prevent FIDO2 from succeeding password authentication, such as missing support for contemporary usage patterns, including account delegation and usage on multiple clients.},

Various works already try to predict vectors or scores using machine learning based on the textual descriptions of the vulnerability to enable faster assessment. However, for this purpose, previous works only use the texts available in databases such as nvd. With this work, the publicly available web pages referenced in the nvd are analyzed and made available as sources of texts through web scraping. A dl based method for predicting the vector is implemented and evaluated. The present work provides a classification of the nvd’s reference texts based on the suitability and crawlability of their texts. While we identified the overall influence of the additional texts is negligible, we outperformed the state-of-the-art with our dl prediction models.},

abstract = {Concise instruments to determine privacy personas – typical privacy-related user groups – are not available at present. Consequently, we aimed to identify them on a privacy knowledge–privacy behavior ratio based on a self-developed instrument. To achieve this, we conducted an item analysis (N = 820) and a confirmatory factor analysis (CFA) (N = 656) of data based on an online study with German participants. Starting with 81 items, we reduced those to an eleven-item questionnaire with the two scales privacy knowledge and privacy behavior. A subsequent cluster analysis (N = 656) revealed three distinct user groups: (1) Fundamentalists scoring high in privacy knowledge and behavior, (2) Pragmatists scoring average in privacy knowledge and behavior and (3) Unconcerned scoring low in privacy knowledge and behavior. In a closer inspection of the questionnaire, the CFAs supported the model with a close global fit based on RMSEA in a training and to a lesser extent in a cross-validation sample. Deficient local fit as well as validity and reliability coefficients well below generally accepted thresholds, however, revealed that the questionnaire in its current form cannot be considered a suitable measurement instrument for determining privacy personas. The results are discussed in terms of related persona conceptualizations, the importance of a methodologically sound investigation of corresponding privacy dimensions and our lessons learned.},

In a dynamic field like cybersecurity, gathering up-to-date information is usually a manual, time-consuming, and exhaustive task.

First, on the basis of a literature review, this paper proposes a novel cybersecurity tool categorization based on corresponding tool types with their respective definitions and core features. Second, it elaborates information used in each category and deduces notions of relevance. Third, it outlines how these findings informed the design of a security dashboard to guide computer emergency response team staff in identifying current threats in open source intelligence sources while mitigating information overload.},

Furthermore, institutions such as state-level Computer Emergency Response Teams (CERTs) are relatively unknown among the population and respondents showed little confidence in German security authorities to cope with largescale attacks and ultimately protect citizens.

abstract = {Business collaboration in the era of digital transformation requires the exchange of operational data. Since data are hardly controllable once they have been published or shared with others, it is highly important that users are clearly informed about who has access to which data and how certain settings can prevent the disclosure of sensitive data. However, giving end users more control over their data through increased transparency could also lead to information overload. This is particularly true in the field of agriculture, where tight schedules put pressure on employees of small enterprises. We conduct an empirical prestudy with 52 German farmers to investigate current data sharing scenarios. From these insights, we derive requirements and a concept for data sharing solutions providing data flow transparency for users. To investigate the behavior of users and the effects of transparent UI controls, we evaluate a prototype with 18 persons. Our evaluation shows that farmers demand flexible and secure tools that adjust to their workflows. Also, data should be stored and processed locally, granting farmers data sovereignty. Although the controls require additional effort, the evaluated transparent controls for data disclosure are easy to use and raise user awareness.},

Betrachtetwerden dafür die Themengebiete Anti-Patterns, Grey Patterns und Dark-Patterns. Anti-Patterns bezeichnen wiederkehrende Lösungen für ein Konzept eines User Interfaces, die trotz guter Intention ungewünschte Nebeneffekte oder Konsequenzen haben. Dark-Patterns dagegen stellen Designentscheidungen dar, die durch Täuschung oder Ausnutzung psychischen Drucks versuchen Nutzer*innen zu Handlungen zu verleiten, von denen die Ersteller*innen des Dark-Patterns mehr profitieren als die Anwender* innen. Der Begriff Grey Patterns wird in dieser Arbeit für alle Design Patterns genutzt, die sich nicht direkt zuordnen lassen. Da es bisher kaum vergleichendeWerke und keinen Konsens zu diesen Themengebieten gibt, ist das Ziel dieser Arbeit ein grundlegendes Modell aufzustellen. Dabei wird durch die Untersuchung bestehender Literatur eine zusammenfassende Taxonomie und ein Vorgehen zur Unterscheidung von Anti-Patterns und Dark-Patterns erarbeitet, die als Grundlage für weitere Arbeiten und zur Entwicklung von Gegenmaßnahmen genutzt werden können.},

In this paper, we analyzed these events in Germany in recent years and found out how they can be detected, and what impact they have on citizens, especially in crisis situations. For this purpose, we take a look at two different approaches to recording internet outages, namely the self-reporting of citizens and automatic reporting by algorithmic examination of the availability of IP networks. We evaluate the data of six major events with regard to their meaningfulness in quality and quantity. We found that due to the amount of data and the inherent imprecision of the methods used, it is difficult to detect outages through algorithmic examination. But once an event is publicly known by self-reporting, they have advantages to capture the temporal and spatial dimensions of the outage due to its nature of objective measurements. As a result, we propose that users’ crowdsourcing can enhance the detection of outages and should be seen as an important starting point to even begin an analysis with algorithm-based techniques, but it is to ISPs and regulatory authorities to support that.},

abstract = {In the last decades, research has shown that both technical solutions and user perceptions are important to improve security and privacy in the digital realm. The field of ‘usable security’ already started to emerge in the mid-90s, primarily focussed on password and email security. Later on, the research field of ”usable security and privacy” evolved and broadened the aim to design concepts and tools to assist users in enhancing their behaviour with regard to both privacy and security. Nevertheless, many user interventions are not as effective as desired. Because of highly diverse usage contexts, leading to different privacy and security requirements and not always to one-size-fits-all approaches, tailorability is necessary to address this issue. Furthermore, transparency is a crucial requirement, as providing comprehensible information may counter reactance towards security interventions. This article first provides a brief history of the research field in its first quarter-century and then highlights research on the transparency and tailorability of user interventions. Based on this, this article then presents six contributions with regard to (1) privacy concerns in times of COVID-19, (2) authentication on mobile devices, (3) GDPR-compliant data management, (4) privacy notices on websites, (5) data disclosure scenarios in agriculture, as well as (6) rights under data protection law and the concrete process should data subjects want to claim those rights. This article concludes with several research directions on user-centred transparency and tailorability.},

This article presents a disaggregated whitebox-based visualisation of critical information as a novel nudge. By segmenting users according to their decision-making and information processing styles, we investigate if the novel nudge is more effective for specific users than a common black-box nudge. Based on existing literature about critical factors in password security, we designed a dynamic radar chart and parallel coordinates as disaggregated visualisations. We evaluated the short-term effectiveness and users' perception of the nudges in a think-aloud prestudy and a representative online evaluation (N=1.012). Our findings suggest that dynamic radar charts present a moderately effective nudge towards stronger passwords regarding short-term efficacy and are appreciated particularly by players of role-playing games.},

abstract = {Organizations affected by a cyber-attack usually rely on external Cyber Incident Response (CIR) consultants to conduct investigations and mitigate the impact. These CIR consultants need to make critical decisions that could have major impact on their clients. This preliminary investigation aims to get a better understanding of CIR decision-making and answers the following questions: (1.) To what extent do experienced CIR consultants use a Recognition-Primed Decision (RPD) Making strategy during their work? (2.) What are the implications for cyber crisis management as well as for training and decision-making? To answer these questions, we conducted a literature review and interviewed six experienced CIR consultants using the Critical Decision Method. Our analysis reveals that CIR consultants recognize situations based on past experiences and apply a course of action that has worked effectively in the past. This course of action is mainly aimed at collecting and evaluating more data. This finding differs from other operational domains such as the military and fire department, where recognition is usually followed immediately by action. For cyber crisis management, this means that crisis management teams should decide to what extent and in what ways they want to mitigate the risk of responding belatedly to cyber events, which could potentially lead to unnecessary data theft and sustained business disruption. Another implication is that crisis management teams should consider whether additional forensic investigation outweighs the expected benefits throughout the response process. For instance, if the likely entry-point of the attacker has been discovered, how much effort should be devoted to exclude other potential entry-points. Reflecting on the status-quo, several implications for training and decision-making are provided.},

abstract = {The relevance of adequate privacy and security behavior in the digital space is higher than ever. However, the exact relationship between privacy and security behavior is rarely discussed in the literature. This study investigates this relationship and the role of socio-demographic factors (gender, age, education, political opinions) in such behavior. Exploratory results of a survey of German private users (N=1,219) show that privacy and security behavior are only weakly correlated and not similarly influenced by socio-demographic factors. While se-curity behavior significantly differs between age and education groups (younger and less educated show less security behavior), no such differences exist for pri-vacy behavior. Additionally, political orientation and opinion has no influence on privacy and security behavior. Thus, this study sheds light on the concepts of privacy, security and corresponding behavior and emphasizes the need for a fine-grained differentiation if either privacy or security behavior is to be improved.},

abstract = {Information and communication technologies affect all areas of civil society. Digitalization opens up new opportunities to address important social issues. The motor of digitalization can be social necessity, technical feasibility, and also a crisis, as the reaction to the COVID-19 pandemic demonstrates: Out of necessity, ideas are created, systems designed and implemented and the value of digital solutions to society becomes apparent. With the digitalization of everyday working and learning, apps for tracing information chains and containing new infections have potential, but also pose social risks. The current COVID-19 crisis seems to put the role of digitalization in a completely new light. Both, to evaluate the value of digital solutions to society and to identify space for innovation is important in times of intense digitalization efforts.
To meet the societal challenges posed by digitalization, it is particularly important to understand how they arise. The use of digital solutions in safety-critical contexts entails dependencies and the threat of various dangers: Infrastructure disruptions and failures can be caused by criminal acts, terrorist attacks, natural disasters, operational disruptions, and system failures. In addition, there is a concern about data arising from the use of digital solutions. Data protection, data sovereignty, data security, and their social perception must always be closely observed. Furthermore, it is important to ensure that digitalization does not lead to a digital divide. New digital solutions require constant evaluation and assessment of the consequences.},

organizations alike. Previous approaches on anti-phishing
measures have started to recognize the role of the user, who,
at the center of the target, builds the last line of defense.
However, user-oriented phishing interventions are fragmented
across a diverse research landscape, which has not been
systematized to date. This makes it challenging to gain an
overview of the various approaches taken by prior works.
In this paper, we present a taxonomy of phishing interventions
based on a systematic literature analysis. We shed light
on the diversity of existing approaches by analyzing them
with respect to the intervention type, the addressed phishing
attack vector, the time at which the intervention takes place,
and the required user interaction. Furthermore, we highlight
shortcomings and challenges emerging from both our literature
sample and prior meta-analyses, and discuss them in
the light of current movements in the field of usable security.
With this article, we hope to provide useful directions for
future works on phishing interventions.},

abstract = {Technological progress can disrupt domains
and change the way we work and collaborate. This paper presents a qualitative study with 52 German farmers
that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data
itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and
consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk.
Having insight into the business data of others along the
supply chain provides an advantage in terms of market
position. This is particularly true in agriculture, where
there is already a significant imbalance of power between actors. A multitude of small and medium-sized
farming businesses are opposed by large upstream and
downstream players that drive technological innovation.
Further weakening the market position of farmers could
lead to severe consequences for the entire sector. We
found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other
hand, privacy itself influences adoption of digital tools.
Our study sheds light on the emerging challenges for
farmers and the role of privacy in the process of digitalization in agriculture.},

abstract = {As a result of the ongoing digitalization of our everyday lives, the amount of data produced by everyone is steadily increasing. This happens through personal decisions and items, such as the use of social media or smartphones, but also through more and more data acquisition in public spaces, such as e.g., Closed Circuit Television. Are people aware of the data they are sharing? What kind of data do people want to share with whom? Are people aware if they have Wi-Fi, GPS, or Bluetooth activated as potential data sharing functionalities on their phone? To answer these questions, we conducted a representative online survey as well as face-to-face interviews with users in Germany. We found that most users wanted to share private data on premise with most entities, indicating that willingness to share data depends on who has access to the data. Almost half of the participants would be more willing to share data with specific entities (state bodies \& rescue forces) in the event that an acquaintance is endangered. For Wi-Fi and GPS the frequencies of self-reported and actual activation on the smartphone are almost equal, but 17\% of participants were unaware of the Bluetooth status on their smartphone. Our research is therefore in line with other studies suggesting relatively low privacy awareness of users.},

In Germany, CERTs in the public sector operate on federal and state level to provide information security services for authorities, citizens, and enterprises. Their tasks of monitoring, analyzing, and communicating threats and incidents is getting more complex due to the increasing amount of information disseminated into public channels.

We derive design and policy implications from our findings, including the need for interoperable and modular architecture, a shift towards service level agreements, cross-platform monitoring and analysis of incident data, use of deduplication techniques and standardized threat exchange formats, a reduction of resource costs through process automation, and transparent reporting and tool structures for information exchange.},

The social media platform Twitter hosts an active cyber security community. Their activities are often monitored manually by security experts, such as Computer Emergency Response Teams (CERTs). We thus propose a Twitter-based alert generation system that issues alerts to a system operator as soon as new relevant cyber security related topics emerge. Thereby, our system allows us to monitor user accounts with significantly less workload. Our system applies a supervised classifier, based on active learning, that detects tweets containing relevant information. The results indicate that uncertainty sampling can reduce the amount of manual relevance classification effort and enhance the classifier performance substantially compared to random sampling. Our approach reduces the number of accounts and tweets that are needed for the classifier training, thus making the tool easily and rapidly adaptable to the specific context while also supporting data minimization for Open Source Intelligence (OSINT). Relevant tweets are clustered by a greedy stream clustering algorithm in order to identify significant events. The proposed system is able to work near real-time within the required 15-minutes time frame and detects up to 93.8\% of relevant events with a false alert rate of 14.81\%.},

These migration movements increasingly rely on digital infrastructure, such as mobile internet access and online services, in order to reach their targeted destination countries. Asylum seekers often use smartphones for information and communication purposes. Even though there are many positive aspects in the use of such technologies, researchers have to consider the perceived risks of this specific user group. This work aims at investigating the use of mobile information technologies by asylum seekers during their flight, especially taking privacy into account. Thus, it examines asylum seekers’ digital privacy perceptions and identifies privacy protection behaviors by conducting a qualitative interview study with 14 asylum seekers who applied for asylum in Germany. The results show that asylum seekers are often aware of the various risks deriving from the use of smartphones and ICT, such as surveillance and persecution by state or non-state actors as well as extortion by criminals. Based on this, this work furthermore outlines different strategies used to manage these risks. Since the lack of privacy and trust leads to avoidance behavior, the insights of this study provide valuable information for the design of assistance apps and collaboration platforms, which appropriately address the specific needs for digital privacy in the context of flight, or for the conception of privacy-enhancing technologies helping to achieve this.},

abstract = {Social media and public cloud computing (SM\&PC) have emerged as important resources of small and medium enterprises (SMEs), but not all SMEs use SM\&PC. The existing research predominantly focuses on the role of either the features of social media and cloud computing in relation to the perceptions of decision makers or the internal capabilities of organization concerning new innovation adoption. By integrating multidisciplinary literature, we, instead, argues that both the perception- and capability-related factors could play an important role in the adoption of new ICT technology, such as SM\&PC. Therefore, we empirically investigated the decision maker's perception-related and SME's capability-related factors that may influence the adoption of SM\&PC in SMEs in Germany. We used quantitative research methods to examine the proposed hypotheses on a sample of 2,404 SMEs from 17 industrial sectors. The results demonstrate that the decisions of German SMEs to engage in social media and cloud computing are not only influenced by the perceptions of SME owners about the usefulness, security aspects, and the implementation costs of SM\&PC, but also by the internal capabilities of an SME, namely the innovativeness of an SME. The results and potential contributions of our research are discussed.},

Currently appointed Information and Communications Technology (ICT) used for coordination and communication is sometimes outdated and does not scale, while novel technologies have the potential to greatly improve disaster response efficiency. To allow adoption of these novel technologies, ICT system designers have to take into account the particular needs of DROs and characteristics of International Disaster Response (IDR). This work attempts to bring the humanitarian and ICT communities closer together. In this work, we analyze IDR-related documents and conduct expert interviews. Using open coding, we extract empirical insights and translate the peculiarities of DRO coordination and operation into tangible ICT design requirements. This information is based on interviews with active IDR staff as well as DRO guidelines and reports. Ultimately, the goal of this paper is to serve as a reference for future ICT research endeavors to support and increase the efficiency of IDR operations.},

Additionally, we ana- lyze the role of socio-demographic factors (gender, age, education, political ori- entation) for security knowledge and behavior. Results show that German pri- vate users have only moderate IT security knowledge and behavior, with as- pects as gender, age, education and political orientation partly having an influ- ence. Men, higher educated and politically moderately oriented participants show higher security knowledge, whereas young people and those less knowl- edgeable about security behave less security-conscious. Additionally, security knowledge and behavior correlate moderately. Therefore, to increase private users' IT security we suggest to increase education and training especially for users being young, politically right-wing or female.},

This can be achieved by using more and new technology and by interconnecting and analysing new and existent devices. Thus, public spaces and buildings will be equipped with more interconnected input and output modalities. This ongoing technolo- gization of public spaces creates opportunities for making everyone's life more secure, while at the same time everyone's personal privacy is endangered. So how is this balancing act tackled and dealt with right now? What fears do citizens have regarding their security as well as their privacy? This paper provides first insights into the topic privacy in smart cities regarding that smart cities need data which can be provided by and of people. The paper raises the question if collecting people's data, and thus enabling smart cities, is ethical and if not, how it can be assured to be ethical.},

Monitoring of platforms in such cases is both a well-established practice and a research area. The question, whether people are willing to renounce privacy in social media during critical incidents, or even allow surveillance in order to contribute to public security, remains unanswered. Our survey of 1,024 German inhabitants is the first empirical study on people's views on social media monitoring and surveillance in crisis management. We find the willingness to share data during an imminent threat depends mostly on the type of data: a majority (63\% and 67\%, respectively) would give access to addresses and telephone numbers, whereas the willingness to share content of chats or telephone calls is significantly lower (27\%). Our analysis reveals diverging opinions among participants and some effects of sociodemographic variables on the acceptance of invasions into privacy.},

abstract = {On-site work of emergency service teams consists of highly cooperative tasks. Especially during distributed search and rescue tasks there is a constant mix of routinized and non-routinized activities. Within this paper we focus on the work practices of the German Red Cross Rescue Dog Units who deal with several uncertainties regarding the involved dogs, the fragility of the respective situations as well as issues of using technologies under enormous time pressure. Smart glasses provide possibilities for enhanced and hands-free interaction in various contexts and a number of approaches have already been applied, aiming at efficient use of the respective technological innovation in private and professional contexts. However, the collaborative potential of smart glasses in time-critical and uncertain situations is still unexplored. Our design case study examines how the on-site work of emergency service teams can be supported by smart glasses: Based on examining the work practices of the German Red Cross Rescue Dogs, we introduce ‘RescueGlass' as a coordinative concept, encompassing hands-free head-mounted display (HMD) application as well as a corresponding smartphone application. Finally, we describe the evaluation of its use in the field of emergency response and management. We show how current features such as ‘fog of war' or various sensors support the cooperative practices of dog handlers, and outline current technical limitations offering future research questions. Our paper provides an initial design probe using smart glasses to engage in the field of collaborative professional mobile tasks.},

Based on responses by 1024 participants in Germany, we examine the diffusion, usage, perception and adoption of mobile crisis apps as well as required functions and improvements. We conclude that crisis apps are still a little-known form of disaster ICT, but have potential for enhancing communication, keeping users up to date and providing a more effective crisis management as supplement to other media channels dependent on different underlying infrastructures. However, they should be adaptable to user characteristics, consider privacy, allow communication and offer valuable information to raise awareness of potential disasters without creating an overload. Also, the familiarity with and trust in crisis apps should be addressed to maximize their beneficial impact on crisis communication and management.

Apps used in these contexts store sensitive and valuable data, creating a need for security measures. It has not yet been researched to what extent certain authentication mechanisms, which can be information-, biometric- as well as token-based, are suitable for individual apps and the respective data. The goal of this work is to assess how perceived security and estimated effort of using such mechanisms, as well as the degree to which app data is considered worth protecting, influence users' choices of appropriate measures to protect app categories. Therefore, we conducted a representative study (n=1024). On the one hand, our results show that a positive correlation between perceived security and effort exists for all investigated non-biometric authentication methods. On the other hand, the study sheds light on the differences between the investigated app categories and the users' choice of the appropriate security mechanisms for the particular category. In contrast to perceived security having a positive influence on a user's preference of mechanism, a relation can hardly be identified for effort. Moreover, app data sensitivity does not seem relevant for the users' choice of security mechanism.},

abstract = {Sicherheitskritische Mensch-Computer-Interaktion ist nicht nur derzeit, sondern auch zukünftig ein äußerst relevantes Thema. Hierbei kann ein Lehr- und Fachbuch, wie dieses, immer nur einen punktuellen Stand abdecken. Dennoch kann der Versuch unternommen werden, aktuelle Trends zu identifizieren und einen Ausblick in die Zukunft zu wagen. Genau das möchte dieses Kapitel erreichen: Es sollen zukünftige Entwicklungen vorausgesagt und versucht werden, diese korrekt einzuordnen. Das ist an dieser Stelle nicht nur durch den Herausgeber, sondern durch Abfrage bei zahlreichen am Lehrbuch beteiligten Autoren geschehen. Neben einem Ausblick auf Grundlagen und Methoden werden dementsprechend auch sicherheitskritische interaktive Systeme und sicherheitskritische kooperative Systeme abgedeckt.},

In this paper we offer insights into how mobile map mashups can assist citizens during infrastructure failures that often occur in large-scale emergencies. Based on a review of approaches and mobile applications from literature and especially from practice, we present SOMAP (social offline map), a mobile app we developed in Android.

abstract = {The complexity and interconnectedness of current working environments encourages organizations, businesses and individuals to collaborate beyond spatial, temporal as well as organizational boundaries. These collaborations are potentially supported by information and communication technology (ICT) among mobile and ubiquitous systems. The academic field Computer-Supported Cooperative Work (CSCW) is primarily recognized for focusing on ICT support for collaboration practices as opposed to the computerizing of formal procedures. ICT, in this view, needs to reflect the dynamic nature of cooperation and collaboration. The notion emergence as coined by Lewes (1875) and interpreted by Goldstein (1999) refers to dynamic contexts that cannot be anticipated in their full extent before they actually occur. Emergent collaboration refers to the need for spontaneous collaboration in novel and changing structures and occurs in application fields such as inter-organizational crisis and emergency management, which by definition contain the unforeseeable.
This dissertation contributes to research into infrastructures for emergent collaboration. Using the example of crisis management, it addresses (1) emergent collaboration practices and how they reveal work infrastructure limitations, (2) novel concepts and artifacts to support emergent collaboration, (3) their effects on the ability to deal with emergent situations and (4) methodological implications for technology design for emergent collaboration infrastructures in inter-organizational settings.
Design case studies (Wulf et al., 2011), inspired by action research (Lewin, 1958) and following Hevner and Chatterjee’s suggestion (2010) to integrate action research with design research, are applied as a practice oriented research method. They contain three phases: an empirical analysis of the practices in the field, the development of innovative ICT artifacts with continuous participation of end-users related to the empirical findings and the evaluation of their appropriation (Pipek, 2005) in practice. In the case reported here, the empirical study on emergent collaboration by police and fire services, aid agencies, energy network operators and citizens in emergencies in two counties in Germany outlined the importance of improvisation work in situation assessment as well as mobile collaboration and reporting practices. The ICT design aimed towards the support of these emergent practices, illustrated by various concepts and prototypes. They comprise (1) an inter-organizational social network for emergency management (SiRena), (2) an inter-organizational situation assessment client (ISAC) aswell as mobile applications for (3) the ad hoc participation in mobile collaboration (MoCo) and (4) the articulation of information needs in mobile reporting (MoRep).
Based on the empirical, technical and practical findings, the subsequent analysis uses the concept of infrastructuring (Pipek \& Wulf, 2009), the integrated perspective on the design and use of information systems, and derives implications for emergent collaboration infrastructures, which contribute overall to the academic fields CSCW, Human Computer Interaction (HCI) and Information Systems (IS).},

This paper presents a study on how emergent ‘collaboration needs' in current work of response teams, who are located on-site and in the control center, could be supported by mobile geo-collaboration systems. First, we present the results of an empirical study about informal work and mobile collaboration practices of emergency services. Then we describe the concept of a mobile geo-collaboration system that addresses the aspects detected in the empirical study and that was implemented as an Android application using web sockets, a technology enabling full-duplex ad hoc communication. Finally we outline the findings of its evaluation in practice and its implications.},

abstract = {Die im Katastrophenschutz beteiligten Behörden und Organisationen mit Sicherheitsaufgaben (BOS) benötigen für Entscheidungen eine aktuelle und akkurate Informationsbasis. Einige dieser Informationen, z.B. Wetterinformationen, können über externe Dienste in Leitstellensystemen visualisiert werden. Andere müssen seitens der zuständigen Einheiten vor Ort via Funk gemeldet werden. Unsere Design-Fallstudie untersucht interaktive Unterstützungsmöglichkeiten dieser Reporting-Prozesse: In einer qualitativen empirischen Studie wurden die Kommunikationspraktiken von Polizei und Feuerwehr untersucht. Darauf aufbauend wurde ein Konzept zur semi-strukturierten Artikulation von Informationsbedarfen erstellt, welches als mobile Android Applikation implementiert und mit potentiellen Nutzern evaluiert wurde. Unser Beitrag illustriert, wie zielgerichtete Informationsanfragen unter Berück-sichtigung angemessener Metadaten das Reporting örtlich verteilter Einsatzkräfte unterstützen können.},

Nach einer Darstellung verwandter Arbeiten werden anhand einer qualitativen empirischen Studie die Informations- und Kommunikationspraktiken mobiler Einsatzkräfte vorgestellt. Hierauf aufbauend folgt die Konzeptionierung und Umsetzung eines mobilen Geokolla- borationssystems, welches an ein bestehendes Krisenmanagementsystem und Geoinformationssystem (GIS) angebunden ist und als Android-App realisiert wurde. Abschließend werden die Evaluationsergebnisse dieses Systems im Anwendungsfeld vorgestellt.},

abstract = {Major electricity breakdowns like the Northeast Blackout (USA) in 2003 or the blackout in most parts of Western Europe in 2005, have shown the fundamental role of electricity in our everyday life. The experiences of these accidents show that power suppliers, firefighters, police, county administration and citizens face multifarious challenges in inter-organizational communication, information and coordination processes during coping and recovery work. In this work-in-progress paper we describe early research dealing with inter-organizational issues in emergency management (EM). We are mainly focusing on supporting social practices in inter-organizational EM, for example collaborative interpretation of emergency situations, ad-hoc coordination or supporting citizen communication and helping routines. Identified from our experiences from related projects, discussions and literature studies, we suggest potential questions and future topics in user-driven software engineering processes for EM and domain specific problems, such as supporting citizen participation, coping with information uncertainties and quality variations or enhancing inter-organizational learning.},

abstract = {One of the most important infrastructures in modern industrialized societies is the electricity network. Due to its fundamental role for many aspects of our everyday life, power infrastructures manifest a strong dependence between power suppliers and customers. Customers take the infrastructure for granted; it appears mostly invisible to them as long as it works, but in the case of breakdowns in power supply customers become aware of the dependence on electricity. They join professional actors in the recovery and coping work with regard to the electricity breakdown: Maintenance workers of the power provider, police, firefighters, red cross, etc. These institutions are professionalized for dealing with such situations, but the people affected by a power outage also need to be considered as actors.},
