摘要: Users and resources in online social networks (OSNs) are interconnected via various types of relationships. In particular, user-to-user relationships form the basis OSN structure, play a significant role specifying enforcing access control. Individual users provider should be allowed to specify which can granted terms existing We propose novel relationship-based control (UURAC) model for systems that utilizes regular expression notation such policy specification. develop path checking algorithm determine whether required relationship between given request exists, provide proofs correctness complexity analysis this algorithm.
