A social network is viewed as a set of people or organizations connected by a set of social relationships, such as friendship or common interests. In the past people would rely on the friends or close associates for information. Today, they search in the web for such information and opinion. And access control to resources is one of the most important technologies for supporting human activities in the digital space, where confidentiality and secure data handling are two most important issues for any such social network users. To realize this control two schemes were proposed: RBAC (Role-Based Access Control) [1] and TRBAC (Temporal Role-Based Access Control) [2] by adding time constraints and role dependencies to RBAC. However, these methods are not effective for temporal activities because of high maintenance costs and inadequacy in safeness. In this paper, we focus on a flexible and secure access control in the real space, by using relations with users and situations, and propose a novel access control which is effective for temporal activities. We evaluate our proposed scheme by implementing a prototype system which shows the effectiveness of this method.
