Problems solved by technology

At present, technologies for integrated identity authentication based on biometrics usually require sequential authentication of multiple biometrics, that is, the identification and authentication of the second biometric will only be enabled if the confidence level of the first biometric is within the preset confidence interval; However, when the confidence of the first biometric identification is less than the minimum value of the confidence interval, the authentication will directly fail; that is, if the acquired biometric cannot be recogniz

Abstract

The invention provides an identity authentication method and device applied to the field of artificial intelligence AI. The invention can be specifically applied to intelligent terminal equipment suchas an intelligent robot for user identity authentication, and comprises the steps of acquiring information of multi-modal biological characteristics of a to-be-recognized user wherein the multi-modalbiological characteristics comprise at least two biological characteristics of the to-be-recognized user; performing identity authentication on the to-be-identified user in parallel according to at least two biological characteristics; and determining an identity authentication result of the to-be-identified user according to an identification result obtained by performing identity authenticationon the to-be-identified user in parallel, with the identity authentication result being obtained based on a confidence coefficient of matching of the multi-modal biological feature and a preset biological feature. According to the technical scheme, interference factors existing in identity authentication through a single biological feature can be effectively avoided, and therefore the robustnessand accuracy of the identity authentication method are improved.

Description

technical field [0001] This application relates to the field of artificial intelligence, and more specifically, to a method and device for identity authentication. Background technique [0002] Artificial intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is the branch of computer science that attempts to understand the nature of intelligence and produce a new class of intelligent machines that respond in ways similar to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machines have the functions of perception, reasoning and decision-making. Research in the field of artificial intelligence includes roboti...
