%X 摘要 近年来，随着无线通信技术和定位技术的发展，与基于位置服务（LocationBased Services，LBS）有关的应用受到越来越多人的使用和重视.一方面LBS为人们的生活带来了很大的便利，而另一方面用户的隐私泄露风险也成为最大的安全威胁.用户的隐私主要包括用户时空位置隐私、有关时间序列的轨迹隐私和用户身份隐私.国内外研究学者针对该问题的基于不同的隐私保护技术系统结构提出了诸多解决方法，可分为假名技术、假位置技术和隐匿时空技术，分别保护了用户的身份信息隐私、位置隐私和轨迹隐私.本文对比现有的隐私保护技术，分析了LBS面临的挑战，归纳了现有的研究工作，并指出了未来的研究方向.</br>Abstract：In recent years, with the development of wireless communication technology and mobile positioning technology, applications relating to locationbased services (LBS) are increasingly taken seriously and used widely. On the one hand, LBS brings people considerable convenience; on the other hand, it becomes a nonnegligible security threat that users’ privacy, mainly including location privacy, trajectory privacy and identity privacy, could be leaked out. Many solutions on the basis of different structures of privacy protection system have been proposed by researchers at home and abroad, which can be divided into pseudonym, faked locations and spatial and temporal cloaking, protecting users’ identity privacy, location privacy and trajectory privacy respectively. In this paper, we contrast the existing privacy protection technologies and analyze challenges LBS is facing. At the same time, we conclude the existing researches and give directions for future research.
