Abstract:
Provided are a method and a device for offline identity authentication. The method includes: acquiring two or more images for identity authentication to constitute a to-be-authenticated multivariate image group; extracting a concatenated PCA convolution feature of each of the images in the to-be-authenticated multivariate image group, to obtain feature vectors; fusing information on the images in the to-be-authenticated multivariate image group based on the feature vectors according to a score fusion strategy with a supervisory signal, to obtain a fusion vector; and inputting the fusion vector to a pre-trained SVM classifier to authenticate and determine whether the images in the to-be-authenticated multivariate image group are consistent with one another, to obtain an identity authentication result.

Claim (Index 7):
The method according to  claim 6 , wherein the encoding based on each of the preset decision weights and the difference signal corresponding to the preset decision weight to obtain the weight signals comprises:\n converting a ratio of the preset decision weights of three matching branches into an integer ratio, and normalizing each of integers in the integer ratio to a range from 0 to 7, wherein the three matching branches comprise a matching branch between the chip image and the surface image, a matching branch between the chip image and the live face image, and a matching branch between the surface image and the live face image; converting the normalized integers in the integer ratio of the decision weights of the matching branches into binary codes, to obtain initial codes; and inserting a highest-order code corresponding to each of the difference signals into the initial code corresponding to the difference signal, to obtain the weight signals, wherein the highest-order code corresponding to the difference signal is one in a case where the difference signal is greater than zero, and the highest-order code corresponding to the difference signal is zero in a case where the difference signal is less than or equal to zero.
