LPM: A Distributed Architecture and Alogorithms for Location Privacy in LBS
Recent advances in mobile communication and development of sophisticated equipments lead to the wide spread use of Location Based Services (LBS). A major concern for large-scale deployment of LBSs is the potential abuse of their client location data, which may imply sensitive personal information. Protecting location information of the mobile user is challenging because a location itself may reveal user identity. Several schemes have been proposed for location cloaking. In the authors' paper, they propose a generic Enhanced Location Privacy Model (LPM), which describes the concept, the architecture, algorithms and the functionalities for location privacy in LBS.
