The traditional location privacy protection means mainly employs reliable central server framework, and it mainly applies the anonymous region meeting the k-anonymity at the anonymous server to replace the real location of users. However, the disadvantages of the central server, such as being attacked easily, high communication cost, etc. are disclosed accordingly. In addition, the anonymous method of most locations is oriented for the European style, and it is not applicable to the road network. In order to solve the above problem, virtual user group-based centerless server framework is proposed for solving the location privacy protection in road network. This algorithm mainly forms the virtual user group with several virtual users in several road segments of the road network, and replaces the real position of the user with a certain point in the section, so as to realize the k-anonymity of user position with the increment nearest neighbor query. Since the algorithm adopts the accurate increment nearest neighbor query method, it guarantees the service quality. The experiment proves that the algorithm can reduce the communication cost effectively and improve the application safety.
