A kind of User-centric fine-grained privacy protection management mechanism with location address transformation based on semantics

摘要

This paper designs a fine-grained location privacy preserving system based on semantics. It is divided into two major modules which are privacy rule setting module and coordinate transformation module. The relationship between these two modules is that the users can use the rule language to express its privacy rules, and when the privacy rule is in the protection mode, the users use coordinate transformation method to protect the their true position information.
