移动社交网络及位置隐私保护研究综述
首发时间:2013-04-09
摘要:随着社交、移动和位置服务(SoLoMo)的融合与发展,现有的隐私保护技术正面临新的挑战,具体表现为:一、社会关系与位置信息的相互影响使SoLoMo 环境中的隐私攻击模型更复杂,现有的位置隐私保护技术与社会关系隐私保护技术不再适用;二、位置数据的收集与分析、挖掘使轨迹隐私泄露问题逐渐凸显,现有的轨迹隐私保护技术不结合具体应用的特点,导致数据可用性差。因此,本文从社交、移动与位置服务中的隐私泄露的若干关键问题入手,综述了移动社交网络及位置隐私保护的研究现状,存在的问题,指出了未来的研究方向。

Privacy-preserving in social, mobile and location-based services
Abstract: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.
Keywords: Location-based Service Location Privacy-preserving Trajectory Privacy-preserving Privacy-preserving in SN Inference Attack
