Abstract

Provision of context-dependent services is triggered when the context satisfies an execution condition. To deliver these services, users' contexts have to be determined by terminals such as GPS. However, GPS has efficiency (it must collect as many contexts as possible to provide services appropriately) and privacy problems (all data is concentrated on one place). Previous studies have addressed only either one of the two problems. We propose a scheme that protects users' privacy while maintaining efficiency by using the Randomized Response Technique.
