摘　　要：基于位置服务(Location based service,LBS)带来生活便利的同时也存在着潜在的隐患。针对该问题,提出一种用户自我感知的位置隐私保护算法。用户向LBS服务器发送请求,自我感知周围其他真实用户的存在与分布情况并形成匿名区域,将匿名区域随机划分为几个子区域,一同将位置信息发送至服务器。仿真结果表明,该方法能够有效提高用户匿名质量,降低合谋攻击成功率,降低通信开销,确保用户位置隐私安全。Although Location based service(LBS)brings convenience in life,it also has potential hidden dangers.Aiming at this problem,this paper proposes a user self-perception location privacy protection algorithm.The user sent a request to the LBS server to self-perceive the existence and distribution of other real users around and formed an anonymous area.The anonymous area was randomly divided into several sub-areas,and the location information was sent to the server together.The simulation results show that the proposed method can effectively improve the anonymity quality of user,reduce the success rate of collusion attacks,reduce communication overhead,and ensure the privacy of user location.
