Systems need to preserve their users’ privacy. In social software, such as online social networks, preserving privacy is especially difficult since content is managed by more than one entity. As a result, users are faced with privacy breaches, where their private content becomes visible to people to which the content is not targeted for. To manage privacy more diligently, social networks have been employing customizable privacy agreements such that each individual can set its own settings. However, these customizations can be in themselves conflicting or may cause inconsistencies when other users’ agreements are in place. To deal with these, this paper develops an approach for managing users’ privacy in online social networks and implements it in a system called PriGuard. The approach starts with a user interface that allows users to enter their own constraints on whom to show content to. The system, then generates appropriate commitments between the users and the system to formalize the users’ needs. The privacy information, such as the relations among users, various content types in the system, and so on are captured inan ontology. Using ontological reasoning, the system checks whether the current situation of the system indeed violates any of the commitments and notifies the user to take appropriate action.
