Abstract
With rapidly popular location-aware applications, location privacy becomes an emerging issue. This paper studies how to protect the two-fold privacy for both client-side and server-side in location-based queries. This technique is a significant component in privacy-friendly Location Based Services (LBS). Participants protect their own privacy. The LBS server protects against excessive disclose of location records in its Points of Interest (POIs) database while the mobile user protects his exact location by the cloaking technique. The proposed hybrid approach can achieve the challenging goal. Our solution integrates the cloaking technique with a cryptographic protocol, Private Set Intersection (PSI). In addition, this solution is secure in malicious model and also practical.
