摘　　要：普适计算将用户的隐私范围从数字世界扩展到物理世界,其中最显著的就是用户的物理位置暴露在计算环境中。因而定位隐私保护研究逐渐成为普适计算领域的一个研究热点。通过对定位隐私的内涵和界定的分析,将定位隐私保护技术划分为主动保护和被动保护两类。分别阐述了其基本特征、设计思想和最新研究发展趋势。在此分析框架下,总结了隐私敏感系统的设计需求,对比了不同分类保护技术的优缺点、应用场合和性能。最后,讨论了存在的问题,指出了未来的研究方向。The pervasive computing extend the boundary of privacy especially user＇s physical location information from digital world to physical world,one of the most remarkable changes is that user＇s physical location is exposed to computing environment.Location privacy is emerging as a new hotspot of research in pervasive computing.In this paper,the technique of location privacy is divided into two types：active and passive,according to analyzing the connotation of location privacy and their measurement.The characteristics,design idea and the latest research program of the seven subclasses are summarized.Based on the analysis framework proposed in this paper,the design requirements of privacy sensitive system are concluded.After comparing the advantages and disadvantages,application and performance of different technique,the problems of current research are discussed,and finally the future directions are pointed out.
