摘要
针对传统的基于位置的服务(LBS)隐私保护模式的不足,提出了一种新的位置隐私保护技术,利用RSA密码体制,构造一种盲签名方案来实现用户真实身份的隐藏,从而达到了保护位置信息的目的,实现用户对位置隐私的完全控制,分析结果表明,该技术能有效降低通信开销以及服务器与客户端的处理代价。
For the flaw of traditional location-based services (LBS) privacy mode, a new protection technology is proposed, which using blind signa- ture scheme based on RSA cryptosystem to protect users' true identity and location information , so as to achieve the purpose of the protection of location information, let the users have completely control of their location privacy. The proposed design has proved its ability in reducing the communication over- head, as well as the processing cost of server and client.
