Conflicts in Online Social Network Privacy Policy

Social network sites have the potential to fundamentally change the character of our social lives, both on an interpersonal and a community level. In the past few years, social network sites have become integrated into the daily practices of millions of users. Social applications provide a convenient approach where users can communicate and share their personal information. However, privacy and information security have been concerned as a critical issue in development social applications. Policy-based management, which is a management approach, has been used to control the information access privilege. Users' policies are more flexible and ease to change. However, different policies may cause conflicts that affect execution of social applications. In this paper, we propose a semantic temporal logic mechanism to detect policy conflict in social network environment.
