In this paper, we solved a location privacy protection in location-based services (LBS) where the mobile user had to report her exact location information to an LBS provider for the purpose of obtaining her wished services. Location invisible had been well proposed and researched to defend user privacy. However, as the nature of the insecure wireless net environment the user’s location information may still be uncovered. We presented a k-anonymity algorithm using encryption for location privacy protection that can improve security of LBS system by encrypting the information transmitted by wireless. The experimental results evidence that the processing time is acceptable in current low-level devices.
