    Design Considerations for Usable Authentication in Smart Homes
    (Mensch und Computer 2021 - Tagungsband, 2021) Prange, Sarah; George, Ceenu; Alt, Florian
    Smart home devices are on the rise. To provide their rich variety of features, they collect, store and process a considerable amount of (potentially sensitive) user data. However, authentication mechanisms on such devices a) have limited usability or b) are nonexisting. To close this gap, we investigated, on one hand, users’ perspectives towards potential privacy and security risks as well as how they imagine usable authentication mechanisms in future smart homes. On the other hand, we considered security experts’ perspectives on authentication for smart homes. In particular, we conducted semi-structured interviews (N=20) with potential smart home users using the story completion method and a focus group with security experts (N=10). We found what kind of devices users would choose and why, potential challenges regarding privacy and security, and potential solutions. We discussed and verified these with security experts. We derive and reflect on a set of design implications for usable authentication mechanisms for smart homes and suggest directions for future research. Our work can assist designers and practitioners when implementing appropriate security mechanisms for smart homes.

    Inclusive Security by Design
    (Mensch und Computer 2022 - Workshopband, 2022) Knierim, Pascal; Prange, Sarah; Feger, Sebastian; Schneegaß, Stefan; Sasse, Angela; Bayerl, Dominik; Hof, Hans-Joachim; Alt, Florian
    With the digital transformation touching all aspects of people’s lives, digital security practices and shortcomings increasingly affect the physical world, with substantial consequences for human quality of life. The way digital security is currently designed is a significant barrier for many users. It creates negative user experiences and makes many people dependent on others to participate in the digital world safely. Understanding, controlling, and acting on digital security aspects is key to a self-determined life. Collaborative research is required to address this important challenge that could bring the digital transformation to a halt. This workshop aims to bring together researchers from the human-computer-interaction and security communities to build an understanding of technical and social requirements for inclusive security.

    Take Your Security and Privacy Into Your Own Hands! Why Security and Privacy Assistants Should be Tangible
    (Mensch und Computer 2021 - Workshopband, 2021) Delgado Rodriguez, Sarah; Prange, Sarah; Alt, Florian
    In the era of ubiquitous computing, users security and privacy is at risk at almost all times. Security and privacy assistants support their users in becoming aware of these risks and taking the appropriate measures to protect their data. However, they often suffer from being too complex, not intuitive and non-engaging. Hence, in order to truly enable less tech-savvy or inexperienced persons to use security and privacy assistants, we argue that such mechanisms must become tangible in the future.
