Abstract

En 中文

One of the major problems of location-based services is ensuring the location privacy of a mobile user. However, it becomes more challenging in the case of a continuously moving user. Though many techniques for preserving location privacy for continuous query scenario have been studied in the last decade, a formal approach for quantification of privacy and justification for the correctness of the privacy guarantee remains mostly at infancy level. In this paper, we present a theoretical model for location obfuscation that is flexible enough to express several obfuscation mechanisms and allow to reason about their privacy guarantees. We illustrate the effectiveness of our theoretical model by analyzing a popular square grid-based obfuscation mechanism. (c) 2018 Elsevier Ltd. All rights reserved.
