摘要:
 近年来,随着移动互联网及智能移动设备的飞速发展,位置服务给人们的生活带来了极大的便利,但是,用户的位置隐私也受到了极大的威胁.文中从LBS位置隐私保护的实际应用出发,根据现有的位置隐私保护模型,分析不同LBS隐私保护的系统结构的优缺点,介绍了在移动分布式P2 P结构的构造方法,提出了基于非可信用户的P2 P加密位置隐私保护方案.该方案建立在所有角色都不可信的基础上,通过使用将位置隐私和用户隐私分开处理的方式及采用加密的方法来保护用户的隐私.该方案能提供精确地理位置服务,获得精确查询结果的同时还能抵御各种恶意角色攻击,包括恶意邻居节点、恶意LBS服务器、两者的合谋攻击以及连续查询攻击和区域密度攻击,有效地保护了用户的隐私信息.
Abstract:
 In recent years,with the rapid development of mobile Internet and portable devices,location services has brought great conven-ience to people’ s lives,but user privacy has also been a lot of threats. Based on the practical application of LBS location privacy protec-tion,according to the existing location privacy protection model,it analyzes the pros and cons of the system structure of different LBS pri-vacy in this paper,and briefly describes mobile construction method of distributed P2P architecture,then an encrypted location scheme of privacy protection for P2P based on non-trusted user has been put forward. The scheme builds on all the roles are not credible,through location on privacy and privacy of users be handled separately,and uses encryption method to protect users’ privacy. The program not on-ly can provide a precise location for precise query results but also safeguard against different kinds of malicious attacks,including mali-cious neighbor nodes,malicious LBS servers,the two conspired to attack,continuous queries and regional density attack,which protect privacy of the user’ s information effectively.
