Offline identity authentication method and apparatus

Abstract

Embodiments of the invention disclose an offline identity authentication method and apparatus, which is used for solving the problems that dependence on a human face database of the public security ministry exists and a chip head portrait, a certificate surface head portrait and a certificate holder head portrait are difficultly identified in consistency in the prior art. The method disclosed by the embodiment of the invention comprises the steps of obtaining two or more images used for identity authentication to form a to-be-authenticated multivariate image group; extracting a concatenated PCA convolutional characteristic of each image in the to-be-authenticated multivariate image group to obtain a corresponding eigenvector; performing fusion on image information of the to-be-authenticated multivariate image group according to the eigenvector and a score fusion policy with a supervisory signal to obtain a corresponding fusion vector; and inputting the fusion vector into a pre-trained SVM classifier to perform authentication judgment on whether images in the to-be-authenticated multivariate image group are consistent or not so as to obtain an identity authentication result.

Description

technical field [0001] The invention relates to the field of pattern recognition, in particular to a method and device for offline identity authentication. Background technique [0002] When performing identity authentication based on the ID card, on the one hand, it is necessary to identify the authenticity of the ID card itself, and on the other hand, it is necessary to identify whether the current user is consistent with the legal holder of the ID card. The former can use chip anti-counterfeiting technology to judge based on whether the machine-reading is successful on the card reader. To further identify the identity, it is necessary to combine the ID card system of the public security department for online verification and identification. This online identification method, on the one hand, needs to obtain the access authorization of the face database of the public security system, which limits the application occasions. On the other hand, it cannot automatically identif...
