  • The Nudge Puzzle: Matching Nudge Interventions to Cybersecurity Decisions
    Item type: Journal Article
    Zimmermann, Verena; Renaud, Karen (2021)
    ACM Transactions on Computer-Human Interaction
    Nudging is a promising approach, in terms of influencing people to make advisable choices in a range of domains, including cybersecurity. However, the processes underlying the concept and the nudge’s effectiveness in different contexts, and in the long term, are still poorly understood. Our research thus first reviewed the nudge concept and differentiated it from other interventions before applying it to the cybersecurity area. We then carried out an empirical study to assess the effectiveness of three different nudge-related interventions on four types of cybersecurity-specific decisions. Our study demonstrated that the combination of a simple nudge and information provision, termed a “hybrid nudge,” was at least as, and in some decision contexts even more effective in encouraging secure choices as the simple nudge on its own. This indicates that the inclusion of information when deploying a nudge, thereby increasing the intervention’s transparency, does not necessarily diminish its effectiveness. A follow-up study explored the educational and long-term impact of our tested nudge interventions to encourage secure choices. The results indicate that the impact of the initial nudges, of all kinds, did not endure. We conclude by discussing our findings and their implications for research and practice.

  • Authenticate As You Go: From Exploring Smart Home Authentication with Daily Objects to Authenticating with Primary Tasks
    Item type: Journal Article
    Zimmermann, Verena; Schäfer, Stina; Dürmuth, Markus; et al. (2025)
    ACM Transactions on Computer-Human Interaction
    Smart home applications aim to increase convenience, yet often require authentication to protect sensitive data. This is non-trivial: effortful authentication contradicts intended convenience, the multitude of devices raises scalability issues, many devices lack suitable interfaces, and the presence of other inhabitants requires intentional and acceptable interactions. To address these issues, we explored new and creative authentication interactions with an interaction relabelling approach using everyday objects. We conducted six focus group workshops with 20 participants in a living room and a kitchen setting that resulted in a variety of creative authentication interactions with analogue and digital objects. Furthermore, participants created authentication interactions based on tasks that they have to or wish to perform anyway such as cleaning the kitchen - thus primary tasks. This led us to explore the option to transform authentication from being an additional, secondary task towards using primary tasks further in an online study with 194 participants. Relevant implications in terms of acceptable authentication task characteristics, user perceptions, arising security challenges, and psychological habit research are discussed.

  • Don’t accept all and continue: Exploring nudges for more deliberate interaction with tracking consent notices
    Item type: Journal Article
    Gerber, Nina; Stöver, Alina; Peschke, Justin; et al. (2024)
    ACM Transactions on Computer-Human Interaction
    Legal frameworks rely on users to make an informed decision about data collection, e.g., by accepting or declining the use of tracking technologies. In practice, however, users hardly interact with tracking consent notices on a deliberate website per website level, but usually accept or decline optional tracking technologies altogether in a habituated behavior. We explored the potential of three different nudge types (color highlighting, social cue, timer) and default settings to interrupt this auto-response in an experimental between-subject design with 167 participants. We did not find statistically significant differences regarding the buttons clicked. Our results showed that opt-in default settings significantly decrease tracking technology use acceptance rates. These results are a first step towards understanding the effects of different nudging concepts on users’ interaction with tracking consent notices.
