Rupam Deb, Sumaya Kazary, Kazi Islam, Reaz Ahmed · 2010
In modern age portable handheld devices are changing the norms of traditional communication structure by introducing mobility and dynamism. In general when a mobile client wants services from a database server, the client has to continuously report its location to the server. With untrustworthy servers, location-based services (LBS) may pose a major privacy threat on its users. In this paper, we propose an efficient architecture to tackle this privacy threat. In the proposed architecture a client's location and messages are hidden from the database server as well as other clients in the network. In this paper, we define the location privacy preservation protocol and analysis the protocol in different threat situations.
