    Between Effort and Security: User Assessment of the Adequacy of Security Mechanisms for App Categories
    (Mensch und Computer 2019 - Tagungsband, 2019) Reuter, Christian; Häusser, Katja; Bien, Mona; Herbert, Franziska
    With the increasing popularity of the smartphone, the number of people using it for financial transactions such as online shopping, online banking or mobile payment is also growing. 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.

    Ein Kampf gegen Windmühlen: Qualitative Studie über Informatikabsolvent_innen und ihre Datenprivatheit
    (Mensch und Computer 2019 - Workshopband, 2019) Schmidbauer-Wolf, Gina Maria; Herbert, Franziska; Reuter, Christian
    Wie werden eigene private Daten geschützt? Um dieser Frage nachzugehen, wurde in einer qualitativen Studie mit sechs Informatikabsolvent_innen erfragt, wie diese die Privatheit ihrer Daten schützen. Das Ziel der teilstrukturierten Interviews war es einen möglichst breiten Überblick über tatsächlich verwendete Techniken und Technologien zum Schutz der privaten Daten zu gewinnen. Während sich die Vermutung bestätigte, dass alle Teilnehmer_innen ein Bewusstsein für die Brisanz ihrer privaten Daten hatten, unterschieden sich die Definitionen ebendieser privaten Daten sowie das Verhalten, um diese zu schützen. Es konnte beobachtet werden, dass viel Wissen in diesem Bereich nicht zwangsläufig zu einem vorsichtigeren Handeln führt. Mögliche genannte Strategien zum Schutz der eigenen Daten sind: Informiert bleiben, Datensparsamkeit, Vermeidung der Produkte bestimmter Konzerne sowie Resignation. Als Motivation für das jeweilige Verhalten wurden sowohl politische, philosophische, utilitaristische, als auch angstgetriebene Gründe genannt. Letztere können in Angst vor Diebstahl und Angst vor Andersbehandlung unterschieden werden.

    Who Should Get My Private Data in Which Case? Evidence in the Wild
    (Mensch und Computer 2021 - Tagungsband, 2021) Herbert, Franziska; Schmidbauer-Wolf, Gina Maria; Reuter, Christian
    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.
