Privacy-Preserving Location Based Queries

该项目旨在为移动用户开发高效的解决方案，使他们能够在不暴露位置的情况下使用基于位置的服务（LBS）。本项目期望通过理论分析和实际实验来证明解决方案的有效性。期望的结果是一个多方信任模型，在多个基于位置的服务之间分发用户位置信息的技术，以及一个在移动环境中保护隐私的实用系统。这将保护个人隐私，增加用户对基于位置的系统的信任。

This project aims to develop efficient solutions for mobile users to consume location-based services (LBS) without revealing their locations. The project expects to demonstrate the effectiveness of the solutions using theoretic analysis and practical experiments. The expected outcomes are a multiparty trust model, techniques to distribute user location information among multiple location-based services, and a practical system to protect privacy in mobile environments. This should protect the privacy of individuals and increase users’ trust in location-based systems.
