基于“声纹+”的无监督可信身份认证

“Voiceprint+”Based Unsupervised Trusted Identity Authentication

近年来,随着移动互联网和物联网的快速发展以及自助终端、无人商店等新业态的兴起,线上网络空间或线下自助空间的无监督身份认证成为人们日常生活不可或缺的部分,需要进行无监督身份认证的场景呈指数级增加.目前,生物特征识别成为用户自我证明的最主要手段,然而部分生物特征一旦泄露,遭到非法利用或非本人意愿情况下"被认证",将严重损害用户自身利益.因此,针对无监督情形下的可信身份认证进行了深度分析,提出了无监督身份认证的五性要求,综合比较了各类生物特征的认证特点及其短板,分析了声纹识别技术运用于无监督可信身份认证的优势,以及基于"声纹+"多维度技术融合用于"从实人到实意"的可信身份认证未来趋势.

In recent years,with fast development of the Internet and the Internet of things(IoT)and the rise of the new forms of business,such as the self-service terminals and self-service stores,online cyberspace and offline physical space unsupervised identity authentication become a necessary part of people's life,those scenarios that require unsupervised identity authentication are increasing very exponentially.At present,biometric recognition becomes a most important way for users to prove themselves.But once the biometrics are used illegally or unwillingly,this will damage users'profits very seriously.For the above mentioned reasons,this paper aims at in-depth analysis on the trusted identity authentication in unsupervised scenarios,proposes the five-feature requirement of unsupervised identity authentication,compares the pros and cons of the authentication features of various biometrics comprehensively,analyzes the advantages of voiceprint recognition technology used in unsupervised identity authentication,and predicts the future trend of trusted identity authentication based on "Voiceprint+ " multi-dimensional technology"going from real person to real intention".
