摘要
智能手机与各类定位技术的发展,使基于位置的服务(LBS)成为日益普及的应用,如何在人们使用LBS服务的过程中保护位置隐私,成为学术界的热点问题。对于LBS的位置隐私保护已有不少研究成果,但距离实际的广泛应用仍任重道远。文章围绕LBS快照查询的位置隐私保护,研究了LBS位置保护算法的主要系统架构以及经典算法,从性能和隐私度等方面对其优缺点进行分析比较,最后给出了位置隐私保护算法面临的挑战和未来的研究方向。
jThe development of smart phones and various positioning techniques have turned the loca-tion-based services (LBS) into an increasingly popular application. Meanwhile, users face thethreats of location privacy disclosure when using LBS. The existing solutions to user location privacyprotection are still far from realistic application. Based on the snapshot query of LBS, this paper sur-veys the related literatures from the framework to the various location privacy protection technologies.The principles, mechanisms and characteristics of various techniques are described in detail. Theperformance and level of the protection are compared, Finally, it concludes with the challenge andfuture development orientation of the location privacy protection technologies.
