位置隐私保护技术研究

Research on technology of location privacy protection

位置服务给人们的生活带来诸多便利的同时,也面临泄漏用户位置信息的危险,这为他人实施不法行为提供了可乘之机。隐私问题已经成为位置服务以及研究人员的一个严峻的挑战。解决隐私问题的关键是在保护个人信息的同时也要保证服务质量,需要在两者之间取得平衡。文中综述了基于轨迹的隐私保护技术和基于位置的隐私保护技术的研究现状与进展,阐述了基于位置和轨迹的隐私保护方法、类型、目标和挑战,分析了隐私保护技术存在的主要问题,并对位置隐私保护技术的发展方向进行了探讨,为位置隐私保护的进一步研究提供参考。

Location service to our life brings a lot of convenience at the same time,user location information is also facing the risk of leakage,which outlaws implementation of wrongful act provides an opportunity.Privacy issues have become a critical challenge for location-based services as well as researchers.The key to solve the problem of privacy is to protect personal information and to ensure the quality of service,and to achieve a balance between the two.this paper reviewed the present situation and research progres based on trajectory privacy protection and based on location privacy protection,the paper expounds the based on the position and trajectory of the privacy protection methods,types,objectives and challenges,and probes into the development direction of location privacy protection,and the main problems of privacy protection are analyzed,which provides reference to the further research of location privacy protection.
