Privacy control in online social networks

Online social networks (OSNs), such as Facebook, operate using various information resources related to their users, which are potentially privacy-sensitive. Protecting information in such an environment is challenging due to interconnected nature of information objects and users, and the fact that both users and the system should be able to specify authorization policies for data access. We study specification, enforcement, and analysis of privacy control policies in OSNs.
