Abstract: In recent years, with fast development of the Internet and the Internet of Things (IoT) and the rise of 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 and 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”.
