基于消息复用的位置服务隐私保护算法

A Message-Sharing-Based Privacy Preserving Algorithm for Location-Based Service

提出一种基于消息复用的位置服务隐私保护(MSPP)算法,用于提供不同安全性需求的位置服务.首先对源消息集中的数据进行预伪装,将通过预伪装算法成功伪装的消息添加到复用消息集.然后,通过消息复用,形成多层伪装区域来保护用户的位置隐私.仿真结果表明,针对不同安全性需求的消息,该机制提高了匿名成功率,缩短了系统平均响应时间.

This paper proposes a message-sharing-based privacy preserving(MSPP)algorithm for providing various security requirements.And first,the data in source message set are cloaked and the cloaked data is put into the message-sharing set.Then,through message sharing,MSPP uses multi-cloaked area to protect users' location privacy.Our simulation results demonstrate that MSPP algorithm achieves high success rate along with low response time.
