摘    要:随着基于位置的服务( LBS)的发展,如何保证用户在使用位置服务时的隐私安全,已成为一个亟待解决的问题。文中对主流的位置隐私保护技术进行了分析和比较。在此基础上,针对移动用户的位置隐私保护,提出了一种基于中心服务器的位置隐私保护方案。该方案针对隐私保护需求的差异性,考虑区域的敏感等级,对敏感区域采用K-匿名和假名进行保护,同时运用脚印来辅助匿名。该方案能在不降低位置服务质量的前提下,有效地保护移动用户位置隐私。

关 键 词:位置隐私  假数据法  K-匿名  脚印

Abstract:With the rapid development of Location-Based Service ( LBS) ,how to ensure the users' privacy security has become an ur-gent problem when they use LBS. In this paper,several primary location privacy protection technologies are analyzed and compared,and a central server-based location privacy protection scheme is proposed for protecting mobile user's location privacy. This scheme consid-ers the sensitive level of area according to different privacy protection needs,uses K-anonymity and pseudonyms to protect location priva-cy in sensitive areas,and applies footprint to assist anonymity. This scheme can effectively protect location privacy of moving object with-out reducing the quality of service.
Keywords:location privacy  false data method  K-anonymity  footprint
