- The increasing number of fitness tracking wearables deployed worldwide poses challenges to the privacy of their users, esp. in terms of transparency. Privacy notifications facilitate transparency by providing users with situational awareness about the pro-cessing of their personal data. We present the results of two online surveys including English-speaking (n(Eng) = 154) and German-speaking (n(Ger) = 150) users of fitness track-ing devices from Europe, conducted to elicit determinants of notification settings. We found evidence for the perceived usefulness of privacy notifications, and for concordant predictors in terms of when and how users prefer to be notified about personal data processing in 12 scenarios related to fitness tracking.

Reconciling the What, When and How of Privacy Notifications in mHealth

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The increasing number of mobile health (mhealth) devices deployed worldwide poses challenges to the privacy of their users, especially in terms of transparency. Privacy notifications constitute a conceptual means to facilitate transparency by providing users with situational awareness pertaining to the processing of their personal data. We present the results of two online surveys with cohorts consisting of English-speaking (n = 154) and German-speaking (n = 150) users of mhealth devices, conducted to elicit viable determinants of notification settings. We found quantitative evidence for the usefulness of privacy notifications, and for concordant predictors in terms of when and how users prefer to be notified about what kind of scenario. We conclude by providing tangible design guidelines for usable Transparency-Enhancing Tools (TETs) that harness privacy notifications to facilitate transparency, and that help users make informed decisions and take action in response.

To Be, or Not to Be Notified : Eliciting Privacy Notification Preferences for Online mHealth Services
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Millions of people are tracking and quantifying their fitness and health, and entrust online mobile health (mhealth) services with storing and processing their sensitive personal data. Ex post transparency-enhancing tools (TETs) enable users to keep track of how their personal data are processed, and represent important building blocks to understand privacy implications and control one’s online privacy. Particularly, privacy notifications provide users of TETs with the insight necessary to make informed decision about controlling their personal data that they have disclosed previously. To investigate the notification preferences of users of online mhealth services, we conducted an online study. We analysed how notification scenarios can be grouped contextually, and how user preferences with respect to being notified relate to intervenability. Moreover, we examined to what extent ex post notification preferences correlate with privacy personas established in the context of trust in and reliability of online data services. Based on our findings, we discuss the implications for the design of usable ex post TETs.
