To achieve privacy protection in the k-anonymity algorithm, replacing the starting positions of k users with the center of the\ncloaked area results in the route from the starting position to the center of the cloaked area probably nonlinear, which will bring\nout the inconvenience for the user. This paper proposes a new anonymous server framework, on which we add the function of\nelectronic map and navigation compared to the original one based on the framework of k-anonymity for LBS. In addition to the\noriginal tasks including computing the center of cloaked area O and the actual query result ri corresponding to the query qi, the\nanonymous server with the new architecture will plan the actual path .......................
