摘要	Location-Based Service (LBS) providers can send geo-tagged data to mobile users who report their current location information. Location-related user privacy is a vital concern since untrusted LBS can monitor and misuse user location information. This paper aims at how to efficiently protect location privacy in query processing. In proxy-based location anonymizers, location cloaking algorithms need heavy bandwidth for query processing after blurring exact locations into a region. To alleviate it, the proposed query framework can integrate location cloaking and data caching. Next, we devise a novel location anonymization algorithm which takes advantage of the caching feature. Finally, we evaluate this solution experimentally for showing its improvement.
