Online Social Networks (OSNs) facilitate many Third-Party Applications (TPAs) that offer users additional functionality and services. However, they also pose serious user privacy risk as current OSNs provide little control over disclosure of user data to TPAs. Addressing the privacy and security issues related to TPAs (and the underlying social networking platforms) requires solutions beyond a simple all-or-nothing strategy. In this paper, the authors outline an access control framework that provides users flexible controls over how TPAs can access user data and activities in OSNs while still retaining the functionality of TPAs.
