Abstract

Aiming at the disadvantage that the query result was unbalanced distributed in the SpaceTwice scheme, this paper proposed a location privacy protection method based on double anchor points in combination with the road network environment. The method used distributed system structure and got rid of the performance bottleneck of the trusted third party. The users could construct an anonymous area according to their privacy requirements, and used the anchor point as a query point to perform incremental neighbor query based on double anchor point, which could make the distribution of query results more balanced and improve query accuracy. Through a large number of experiments on this method under different road network environments, the experimental results show that this method can improve the query efficiency while improving the accuracy of the query.
