抗轨迹差异识别攻击的相似轨迹实时生成方法
Real-time similar trajectory generation algorithm for resisting trajectory difference identification attack
摘要
Abstract
To address the problem of a trajectory difference identification attack when a user uses location-based services for continuous queries, this paper provides an algorithm for generating a similar real-time trajectory to protect the user's personal privacy based on trajectory r-anonymity.The algorithm utilizes an anonymous server to generate a set of dummy locations in real time with the real location of the user, and these locations are composed of similar trajectories of the real user to make the real trajectory fuzzy.The probability of successful trajectory difference identification attack is then reduced.This algorithm achieves real-time trajectory anonymity in continuous location queries.Performance analysis and simulation with other algorithms further verify the effectiveness of the presented algorithm in protecting a user's privacy, as well as the efficiency of the algorithm.关键词
