ELECTRONIC DEVICE, IDENTITY AUTHENTICATION METHOD AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/136912
Kind Code:
A1
Abstract:
The present application relates to an electronic device, an identity authentication method and system, and a storage medium. The method comprises: after voice data of a target user is received, extracting a voiceprint feature of a pre-set type of the voice data by using a pre-set filter, and constructing a voiceprint feature vector corresponding to the voice data based on the voiceprint feature of the pre-set type; inputting the voiceprint feature vector into a pre-trained first model, and determining a triphone feature corresponding to each frame of a voice of the voice data and constructing a triphone feature vector corresponding to all the triphone features of the voice data; inputting the triphone feature vector into a pre-trained second model so as to construct a current voiceprint differentiation vector of the target user; and calculating a spatial distance between the current voiceprint differentiation vector and a pre-stored standard voiceprint differentiation vector of the target user, authenticating the identity of the user based on the spatial distance, and generating an authentication result. By means of the present application, the accuracy of identity authentication can be improved, and the financial security can also be improved.
