The Privacy-Value-App Relationship and the Value-Centered Privacy Assistant
share
Many of us make quick decisions that affect our data privacy on our smartphones without due consideration of our values. One such decision point is establishing whether to download a smartphone app or not. In this work, we aim to better understand the relationship between our values, our privacy preferences, and our app choices, as well as explore the effectiveness of a smartphone value-centered privacy assistant (VcPA) at promoting value-centered app selection. To do this, we conducted a mixed-methods study that involved two phases. The first was an online survey of 273 smartphone user's values and privacy preferences when considering whether to download one of two apps (Lose It! and OpenLitterMap). Our results suggest that values and privacy preferences are related in an app or context-dependent manner. The second phase was testing the VcPA with 77 users in a synthetic Mock App Store setting. We established usability of a VcPA, with the VcPA helping some users more than others with selecting apps consistent with their selected value profile. Future qualitative and context-specific explorations of user perspectives could contribute to adequately capturing the specific role of values for privacy decision-making and improving the VcPA.
