Collaborative data sharing in online social network resolving privacy risk and sharing loss

Abstract

Nowadays, Online Social Networks (OSNs) is popular all over the world. Millions of people join such networks to share their personal and public information and also to make new friends and relations. But there arises several security and privacy issues related to these network since users may have contact with persons who are known to them as well as unknown to them. There are many mechanisms to provide privacy on shared data but enforcing privacy concerns over data associated with multiple users is of great concern as there are chances for privacy risk and data sharing loss. In this paper, privacy setting for a shared data is discussed where multiple users, other than owner, who shares the same data can provide their own privacy policies on shared data.. Privacy conflicts are resolved using a conflict resolution mechanism which will calculate the privacy risk and sharing loss associated with each controller. Thus in this paper a systematic solution that facilitate collaborative management of shared data in OSNs and a conflict detection and resolution mechanism to cope with privacy conflicts in data sharing is addressed.
