The advent of the smartphone has heralded in an era of unprecedented access to rich user data. This has allowed third-party applications to innovate by supporting new interaction modalities, better integrating with usersâ lifestyles, and making relevant information more accessible. At the same time, the abundance of personal data presents very real privacy risks. In this talk, I discuss previous and ongoing human subjects research to help users make more informed choices about how their personal data is accessed. I present previous work on smartphone platforms that has provided insights into usersâ behaviors and preferences, as well as how to design systems that empower users to make better privacy decisions by operationalizing Nissenbaumâs theory of âprivacy as contextual integrity.â I cover several studies that my group has performed to examine how people currently use smartphones to make decisions, how we have modified the Android platform to facilitate better privacy decision-making, and finally, how we are using our infrastructure to further audit third-party applications for privacy violations at scale.
