Abstract:

This paper proposes a provable secure trajectory privacy preserving scheme to solve the trajectory privacy leakage problem for continuous queries in location-based service. Firstly, the security model is established by analyzing the security requirement, that is indistinguishably sending messages, about the trajectory privacies for continuous queries based on Silent Cascade privacy preserving scheme. Secondly, trajectory privacy preserving scheme for continuous queries in user motion is constructed by using the bilinear mapping. Finally, the scheme is proved from the perspective of provable security, and compared the security with other schemes. The results show that the scheme not only has provable security and high quality of service, but also can resist continuous query attack.

Key words: location-based service, trajectory privacy, provable secure, privacy preserving
