MULTIPARTY ACCESS CONTROL AND KEY AGREEMENT FRAMEWORK FOR ONLINE SOCIAL NETWORKSMultiparty Access Control and Key Agreement • February 8th, 2014
Abstract - Social network is a network consists of many number of users and maintains the relationship between them. Social networks can be accessed from anywhere in the world. ONLINE social networks (OSNs) such as Facebook, Googleþ, and Twitter are designed to enable people to share personal and public information and make social connections with friends, coworkers, colleagues, family, and even with strangers. OSN experienced a tremendous growth in the recent years, with new features and application. This paper pursues a systematic solution to facilitate collaborative management of shared data in OSNs. Initially it begins by examining how the lack of multiparty access control (MPAC) for data sharing in OSNs can undermine the protection of user data. Some typical data sharing patterns with respect to multiparty authorization in OSNs are also identified. An MPAC model is formulated to capture the main features of multiparty authorization requirements that have not been addressed so far
