Embodiment Construction
[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0052] The access control game theory method is a new research method to solve the privacy protection problem. The game theory is applied to the location privacy protection. The privacy protection method of the game theory describes the benefits and costs of the participants through mechanism design, formulating strategies, and simulating their rationality. The selection process, which finds the best solution for all parties by analyzing the equilibrium of the ...

The invention discloses a mobile location privacy protection access control method based on game theory. The method includes: calculating the weight value of each information category according to the information category; calculating the access control threshold corresponding to each visitor level according to the visitor level; Pre-judgment based on the current access behavior of the visitor to obtain the pre-judgment result; calculate the amount of information currently accessed by the visitor; obtain historical access records, and calculate the total amount of information based on the amount of information currently accessed by the visitor; compare the access control threshold corresponding to the visitor level and The size of the total amount of information determines the access control result; according to the previous judgment result and the access control result, the access control threshold is adjusted by using the game theory strategy benefit matrix. The invention can control the access of the private information of the mobile location from the perspective of the service provider, aiming at the leakage of the private information of the mobile location which is easy to occur in the data application.
Description
technical field [0001] The invention relates to the technical field of network privacy protection, in particular to a game theory-based mobile location privacy protection access control method. Background technique [0002] At present, with the rapid development of mobile communication technology and Internet technology, location-based services (location-based services, LBS) are more and more applied. Users exchange their own location information for convenient location-based services. Location privacy protection is mainly aimed at information release and information query, and is mainly realized through anonymous technology, encryption technology, and access control technology. Among the anonymous technologies, k-anonymous technology is the most widely applied research. Data encryption technology, such as secure multi-party computing technology, homomorphic encryption technology. There are three main protection technologies for trajectory privacy, fuzzy processing, publi...
