PRIVACY IN SOCIAL COMPUTING

The emerging literature on multi-party privacy management has investigated how to reconcile users’ conflicting privacy preferences with respect to commonly owned (or jointly managed) content at the micro-scale. I am interested in related, but largely unexplored questions. What are the longitudinal effects of repeated negotiations over jointly managed content amongst users in a social network? How do individuals’ sharing decisions change over time; who are the most influential users; and how do they determine the trajectory of the system? What are the privacy gains and losses from the individual and collective perspectives? Ideally, these longer-term considerations will inform reconciliation algorithms and guide relevant policy.
