Collaborate Privacy Protection Based on Virtual Tracks in Position Privacy Protection
Zhao Yun-hu · 2015
This paper proposed a collaborative privacy protection based on virtual tracks(VTPP),without relying on a trusted third-party agent.Users create virtual tracks and collaborate through self-organization communication.A convex polygon cloaked area is created to protect users' location privacy,causing that the location cloaking quality and query result accuracy are improved.Our simulation results demonstrate that VTPP algorithm achieves higher cloaking success rate along with lower service response time.
