基于移动群智感知的社交网络隐私保护方法研究

Research on Privacy Protection Method of Social Network based on Mobile Group Intelligent Perception

笔者对LBS系统的含义、开发进程和安全性进行了说明,对LBS的位置保密管理,也就是它的基本结构、保密手段等进行了说明,对LBS的位置保密管理程序中存在的问题以及其攻击程序进行了解释说明。通过自主生成可信第三方服务器,采用基于位置K-匿名的同心圆匿名算法,对手机客户端的精确位置信息进行封装处理,生成匿名位置区域反馈,由手机客户端接收实现查询服务功能,避免客户端与提供商之间隐私信息的直接交互,进而解决非可靠提供商的非法操作和侵权问题。

The author explains the meaning,development process and security of lbs system,the location secrecy management of lbs,which is its basic structure and secrecy means,is explained,the problems existing in the location secrecy management procedure of LBS and its attack program are explained.In this paper,a location area protection scheme based on central server structure is designed to provide users with safe and reliable location service.Through the independent generation of trusted third-party servers,based on the location K-anonymous concentric circle anonymous algorithm,the mobile phone client's accurate location information encapsulation processing,generate anonymous location region feedback,by the mobile client to receive the completion of the query service function,to avoid the client and provider of private information between the direct interaction,in order to solve the problem of illegal operation and infringement of non-reliable suppliers.
