| Abstract: | The popularity of mobile devices has brought new opportunities for the development of location-based service （LBS） applications， but the trajectory privacy leakage caused by the use of LBS has become a hidden danger in the popularity of LBS. The trajectory generalization method is a trajectory privacy protection technology， which can improve service quality while protecting trajectory privacy. Based on the characteristics of the group-based trajectory privacy protection technology， the trajectory generalization method that does not consider the moving trend is analyzed， and the trajectory privacy protection method based on the moving trend is summarized and the future research direction is prospected. |
