Abstract:

Access control restricts illegal users’ access to data by verifying the legitimacy of the identity of visitors, thus effectively avoiding privacy leakage. However, the method does not consider the user privacy information, the granularity of access control is relatively coarse, can not meet the needs of all privacy subjects, and can not protect the user privacy information to the maximum extent. This article aims to put forward a kind of reasoning based on ontology to protect privacy information access control mechanism, this mechanism can be from the perspective of all privacy subject's privacy information, the use of ontology reasoning method used for access control, the information was optimized from the aspects of access control granularity, and from the angle of the subject of privacy and considering the privacy requirement more privacy subject. Experimental analysis shows that the access control mechanism proposed in this paper can better protect user privacy.

Key words: ontology reasoning, privacy protection, access control, semantic analysis
