Abstract

The invention discloses an access control system and an access control method of the fine-grained privacy security. The access control system of the social networking service fine-grained privacy security comprises a strategy management module, a social networking service group control module, a request processing module, an access control module, an optimizing module and an execution module. The strategy management module is used for maintaining and combining access control strategies; the social networking service group control module is used for maintaining all attribute sets; the request processing module is used for verifying identification; the access control module is used for carrying out the decision for the access request to obtain a decision result; the optimizing module is used for carrying out the exclusiveness processing on the decision result; the execution module is used for executing the decision result. The access control system is used for controlling the security of data flow in the social networking service, a more fine-grained access control mechanism is provided for a user, the user privacy can be protected, and the application requirement of the social networking service can be met.

Description

technical field [0001] The invention belongs to the field of network and information security, and in particular relates to an access control system and an access control method for data security and privacy protection of users in a social network. Background technique [0002] At present, social networking is one of the main technical applications of the Web 2.0 model. It provides a platform for users all over the world to express themselves and communicate with each other, helping them conduct online social interactions or share information and resources with other users. . With the rapid development of social networks, people are more and more concerned about data security and privacy leakage in social networks. The problem of privacy leakage in social networks is not only caused by the leakage of social network databases, but also from the FOF (Friend of friend) model used in the design of social networks. If this model does not have an effective and fine-grained acces...
