摘要
本文针对其中的时间相关性很强的连续查询中的用户隐私问题,在cachecloak方案的基础上进行了改进,使得其可以一定程度上解决时间相关性很强的LBS中连续查询用户的隐私,同时也提出了追踪者的熵模型,来对算法有效性进行评估。最后文章指出了本方案中假查询在保护用户隐私方面的作用。
This article user querying continuously iSStill under the threat of being traced .To solve the problem, we proposed a new method based on cachcloak program, so that it can be protect the user＇slocatien privacy. We also made a tracers entropy model,; to validate the algorithm. Finally, the article pointed out that fake query＇s importance in protecting users＇ privacy.
