METHOD OF BIOMETRIC AUTHENTICATION OF A USER AND A COMPUTING DEVICE IMPLEMENTING SAID METHOD Russian patent published in 2019 - IPC G06F21/32 G06N3/02 

FIELD: computer equipment.

SUBSTANCE: invention relates to computer engineering, intended for user authentication. Technical result is achieved by receiving an FM^st._D card iris signs of a legitimate user of the computing device, extraction from an FM^inc._D card image iris signs of the current user of the computing device by processing this image of the iris of the current user with the convolutional neural network, implementation of FV_sh. vector construction comparisons of upper level by performing element-by-element operation on elements I^inc._d,i of said FM^inc._D card features and corresponding elements I^inc._d,i of said FM^st._D card features and realizing FV_sh. vector representation features of comparison of upper level into another feature space.

EFFECT: high accuracy of biometric authentication of a user by reducing the probability of errors during biometric authentication of a user.
