Internet privacy has become a hot topic recently with both the advent of Online Social Networks and a significant amount of publicity related to privacy. For the last few years we have been examining the leakage of privacy on the Internet: how information related to individual users is aggregated as they browse seemingly unrelated Web sites. Our results show increasing aggregation of user-related data by a steadily decreasing number of entities.

I will present results from three studies on leakage of personally identifiable information (PII) via Online Social Networks (both traditional and mobile OSNs) and popular non-OSN sites. I will also present the current status of both technical and non-technical attempts to ameliorate the problem.
