The proliferation of GPS-enabled mobile devices has made location-based services (LBSs) very popular in mobile networks and protecting user's location information has become a critical issue of it. In a typical location-based service framework, the LBS requires the user to provide precise location information to assure better Quality of Services(QoS), while the user wants to hide this information as much as possible. This dilemma of privacy and quality of service trade-off has been studied in literature extensively. In this paper, we propose a spatial obfuscation framework, Privacy Preserving Voronoi Cell (PPVC) based on Voronoi diagram. In this framework user's region of interest (ROI) is divided into n sectors and each sector is concealed with an irregular quadrilateral, generated from a n-gon Voronoi cell and user's location is confounded within a convex region called Anonymity Zone. We evaluate PPVC with simulated environment, showing the efficiency and efficacy of the proposed framework. Finally, we implement it on Android phone with a user centric privacy scale. |
