Abstract

Social networking and privacy have often been depicted as irreconcilable. People holding this view have declared that the success of sites such as Facebook marks the end of online privacy: "people have voted with their feet and shown they didn’t care".  In this presentation, we will examine data collected through a series of pilots designed to better understand people’s privacy preferences in the context of mobile social networking, with a particular focus on location sharing. Our results strongly suggest that, not only do people care about their privacy, but that mobile social networking applications that have failed to give users adequate privacy settings have miserably failed. As it turns out, well-designed privacy settings can make social networking applications such as location sharing more valuable to users, enabling them to selectively share information with a wider range of "friends" and across a broader range of scenarios. The challenge is that beyond mundane "check in" scenarios such as those supported by Foursquare, location sharing gives rise to fairly diverse and complex privacy preferences. Capturing these preferences seems to be beyond the grasp of current user interface technologies. An important part of this talk will be devoted to ongoing research on user-oriented machine learning techniques intended to reduce user-burden and help users converge towards privacy policies they feel more comfortable with.
