Preserving user location privacy for location-based service
Location privacy has been a great concern to users who need the location based service on networked devices such as mobile phones and personal computers. Location based service usually relies on a location server, which is commonly regarded as semi-trusted or honestbut- curious. To protect user privacy their location information must be protected against the location server. We propose a protocol which captures user location privacy, while the user can still receive the requested service from a service provider, and does not reveal the user's exact location to the location server. Our approach offers the applicability to real-world applications.
