Title:
IDENTITY AUTHENTICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/162053
Kind Code:
A1
Abstract:
An identity authentication method, comprising: acquiring a voice characteristic of an input voice, and matching the voice characteristic to a pre-stored target voiceprint model, obtaining a voiceprint match score (11); segmenting the input voice according to the voice characteristic and a target text model, and acquiring a number of initial segmentation units and initial voice segmentation units (12) - if the number of initial voice segmentation units is greater than or equal to a first threshold, performing forced segmentation on the initial segmentation units, causing the total number of segmentation units to be equal to the number in a preset target text; matching the voice characteristic of each segmentation unit with every target text model, obtaining a segmentation unit text match score for each segmentation unit and each target text model (13); performing identity authentication according to the segmentation unit text match scores, voiceprint match scores and a pre-trained probabilistic neural network (PNN) classifier (14). The present method realizes the goal of two-factor authentication of a user, increasing system security.
