Cache Management Techniques for Privacy Preserving Location-based Services

In order to access location-based services, mobile users have to disclose their exact locations to service providers. However, adversaries could collect the location information for purposes against mobile users´ privacy. There are existing solutions for privacy protection by utilizing the K-anonymity model. However, the computational and communication costs are high. This research proposes cache management techniques for further improving user privacy protection, saving computational power, and decreasing communication costs.
