Abstract

Android apps ask users to allow or deny access to sensitive resources the first time the app needs them. Prior work has shown that users decide whether to grant these requests based on the context. In this work, we investigate user comfort level with resource accesses that happen in a background context, meaning they occur when there is no visual indication of a resource use. For example, accessing the device location after a related button click would be considered an interactive access, and accessing location whenever it changes would be considered a background access. We conducted a 2,198-participant fractional-factorial vignette study, showing each participant a resource-access scenario in one of two mock apps, varying what event triggers the access (when) and how the collected data is used (why). Our results show that both when and why a resource is accessed are important to users' comfort. In particular, we identify multiple meaningfully different classes of accesses for each these factors, showing that not all background accesses are regarded equally. Based on these results, we make recommendations for how designers of mobile-privacy systems can take these nuanced distinctions into account.
