A path-based access control method for location obfuscation in mobile environment

In order to provide an effective location privacy protection method for mobile environment, many researches on location privacy protection focus on the anonymity, but few of them can be used for access control. Considering the impact of history moving path, we give the concept of access probability, and it can be used to correct the parameter of obfuscation. Then we give the access control methods and some examples to show their effectiveness. At last, we give the process of authorization evaluation. The path-based access control model for location obfuscation can effectively protect location privacy in mobile environment, and it is more accurate than the traditional one.
