U+F Social Network Protocol: Achieving interoperability and reusability between Web Based Social Networks

Abstract

Along the time many Web Based Social Networks (WBSNs) have appeared, but not all of them offer the same services. Users may use multiple WBSNs to satisfy their requirements. Besides, operations such as the creation of accounts or the establishment of groups, are repeated in all of them, being a tedious issue. To address this matter, this paper proposes a protocol, based on the UMA core protocol and the FOAF project, to attain interoperability and reusability of resources, identity data and access control policies across different WBSNs. Moreover, an evaluation and a security analysis are presented.
