Abstract:
The sharing of personal and sensitive data has emerged as a popular activity over online social network. The availability of this information obviously raises privacy and confidentiality issues. The current access control models provided by online social network do not allow users to specify their access control on base of time, location, or under other circumstances. In this paper, we propose an access control model for social networks to express much more fine grained access control policies than the existing models, the OrBAC model is used because it provides a complete model to specify contextual and dynamic access control requirements. We also propose a logic specification of OrBAC with Temporal Logic of Actions.
