基于路径混淆的实时轨迹隐私保护方法
Real-Time Trajectory Privacy Protection Method Based on Path Obfuscation
摘要
Abstract
Due to the limitations of traditional trajectory privacy protection algorithms in dealing with real-time problems,a trajectory privacy protection algorithm based on path confusion is proposed for the privacy protection processing of real-time trajectories.The algorithm can solve the problems of insufficient trajectory data or availability of trajectory data in traditional path confusion algorithms.The vehicle trajectories are grouped and selected by the vehicle adaptive time win-dow algorithm,and the privacy protection effect of the trajectories is improved through the obfuscation algorithm.Com-paring the availability of trajectory data in experiments,it is verified that the proposed algorithm is more effective in pro-tecting vehicle privacy than other traditional methods,and the obfuscated trajectory data is more available.关键词
