Abstract

Many new cell phones enable precise location measurement using GPS, and operators plan to exploit this by providing location-based services. However, the user can lose some privacy in revealing his GPS-measured location, which is an order of magnitude more precise than the network operator's best estimate. We propose a protocol to allow anonymous use of location-based services, without revealing the user's identity and location to any third party.
