Protecting location privacy through Identity Diffusion

With the proliferation of new online services and wireless personal devices, location-based services and applications for mobile users are widespread in use today. But the privacy of these users exposes to others increasingly in accessing those location based services. Exposure of the location information may result in privacy threat by malicious servers and hackers. In this paper, we propose a new framework that mobile users can enjoy conveniently the services provided by location-based server (LBS), and also protect their location information. This framework prevents mobile users´ location information from exposing in two ways: providing the server with fake identities; two different ways of diffusing a number of fake queries with the real query hidden when and where it was issued.
