Abstract With the development of mobile internet, protecting location privacy has already been an important issue. Based on previous studies and the drawback of traditional algorithms, the paper proposes a novel algorithm for protecting location privacy. The algorithm is based on the voronoi map of a road network, considers the problem of side-weight inference, and utilizes the information entropy as metrics. Meanwhile, the algorithm can defense the attack of side-weight inference and replay. Lastly, we verified the algorithm based on the real data of the road network. Results of experiences show that the improved algorithm has the better performance on some key performance metrics.
