摘　　要：近年来,随着移动互联网技术的发展和用户需求的增加,网络空间中各种虚拟账号越来越多,同一用户在不同应用甚至同一平台拥有多个账号。同时,由于网络空间的虚拟性导致用户的虚拟身份与真实社会身份之间的关联通常较弱,网络空间违法用户存在发现难和取证难的问题。因此,在服务推荐和调查取证等需求的推动下,以网络空间用户虚拟身份聚合和虚实身份映射为主要研究内容的用户身份对齐技术得到了快速发展。为此,对网络空间用户身份对齐技术进行了梳理,首先对该技术解决的科学问题进行了阐述;其次介绍了该技术所用到的用户身份典型特征和涉及的相关技术;然后对可供研究的数据集与验证标准进行介绍;最后对所提技术面向的应用场景进行了详细分析,并基于此讨论了用户身份对齐技术未来的研究方向以及面临的挑战。In recent years,with the development of mobile Internet technology and the increase of user demand,there are more and more various virtual accounts in cyberspace,and users always have multiple accounts in different applications or even the same platform.At the same time,due to the virtual nature of cyberspace,the relationship between the users' virtual identity and the real social identity is usually weak,and the illegal users in cyberspace are difficult to find.Therefore,driven by the needs of service recommendation and evidence collection,the user identity linkage technology,with cyberspace user virtual identity aggregation and virtual-real identity mapping as the main research content,has been developed rapidly.For this reason,the user identity linkage technology in cyberspace is summarized.Firstly,the scientific problems solved by this technology is defined,and then the typical characteristics of the user identity and the related technologies are introduced.Finally,the datasets and verification stan-dards are presented,and the challenges of the user identity linkage are discussed.
