探讨了考虑背景信息的位置和查询隐私保护方案，如基于背景信息的虚假位置k-匿名方案、同时保护位置和兴趣的隐私保护方案、基于交互的隐私保护方案，还探讨了基于用户隐私链拆分的实名认证和身份隐私保护策略；认为在避免可信第三方参与，敌手能够获取到背景信息的前提下，能够实现对用户身份、位置和查询隐私的保护，达到信任机制和隐私保护的有机结合将是未来隐私保护发展的趋势。

In this paper, we discuss the location and query privacy mechanism which considering the background information, such as the k-anonymity based on background information, the privacy mechanism that preserves the location and interest and privacy preservation mechanism based on interaction. The real-name authentication based on user privacy chain separation and identity privacy mechanism are also discussed. In order to avoid the trusted party, and the background information can be obtained by an adversary, it wil be the tendency that the user ’s identity, location and query can be kept private, and trust mechanism and privacy protection can be combined.
