The current trends of social networks are indirectly requiring users to become system and policy administrators for protecting their content in cyber-enabled social setting.  This is further complicated by the rapid growth rate of social networks and by the continuous adoption of new services on social networks, requiring more systematic user-centered access control. In addition, research has increasingly recognized the risk of misuse of personal data processed by online social networking applications and the lack of awareness among the user population. This talk discusses a comprehensive and compelling framework called SNGuard (Social Network Guard) that satisfies diverse privacy properties, access control issues, identity management requirements, and usage patterns.
