移动社交网络及位置隐私保护研究综述

Privacy-preserving techniques which aim at protecting entities'sensitive information not been exposed are getting more and more attentions. Nowadays, the integration of social, mobile and location-based services brings new challenges to traditional privacy-preserving techniques, expressed specifically as: location privacy leakage; trajectory privacy leakage and social privacy leakage. This project aims at systematically address privacy leakage problems in SoLoMo environment. The research issues in this project include privacy leakage risk analysis; location privacy-preserving in the context of social networking; utility-based trajectory privacy-preserving techniques; differentially social relationship privacy-preserving techniques; evaluation strategies for service quality and data quality, etc. The studies will establish solid basis for privacy-preserving and the development of mobile web.
