摘　　要：5G时代的到来使基于位置的服务(LBS)应用更加广泛,但用户在享受LBS带来的巨大便利时,也会面对由位置服务引发的诸多隐私泄露问题。为了加强匿名的安全性,提高数据效用,对抗拥有一定背景知识的攻击以及保护用户的敏感信息,研究者们提出了基于语义的位置隐私保护机制。首先,对位置隐私保护系统结构和传统的保护技术进行介绍;其次,分析了基于语义的隐私泄露和攻击方式,给出了结合语义的位置隐私保护需求,重点从单点位置隐私保护和轨迹隐私保护两个方面综述了基于语义的位置隐私保护研究中最新的关键技术和成果;最后,对未来技术发展趋势和下一步研究工作进行展望。The arrival of the 5G era makes Location-Based Service(LBS)more widely used,but users also have to face many privacy leakage issues caused by LBS when they enjoy the great convenience brought by LBS.In order to strengthen the security of anonymity,improve data utility,resist attacks with certain background knowledge and protect users’sensitive information,researchers proposed the semantics-based location privacy protection mechanism.Firstly,the structure of location privacy protection systems and traditional protection technologies were introduced.Then,several typical privacy leakage and attack modes based on location semantics were analyzed,the location privacy protection requirements combined with location semantics were given,and the key technologies and achievements in the latest research of semantics-based location privacy protection from two aspects of single-point location privacy protection and trajectory privacy protection were summarized.Finally,the future technological development trend and the next research work were prospected.
