Abstract

As one of the most popular network applications, online social network system has gained huge adoption in the past few years. Campus social network system is a special type of social network system which focuses on providing information communication, knowledge sharing, and online collaboration services to campus users in colleges and universities. In this paper, we discuss the design of relation based access control in campus social network system which is decided by the collective efforts system designers, system administrators, and especially users of the system. Generally speaking, relation based access control in campus social network system is defined in terms of users can establish relationships; and they can also assign relation based permissions on information and resources when they release them. It consists of user-centered access control and group-centered access control which deal with access control of information and resources released in users’ personal space and groups’ shared space respectively. Once a campus social network system is put online, access control in it is actually decided by the collective intelligence of its users. Specifically, it's built upon collective intelligence that is reflected through users’ identity, their social relationships and permissions that they set on their profile and created content. In a word, relation based access control in campus social network system adopts a collective intelligence model.
