METHOD, TERMINAL AND SYSTEM FOR BIOMETRIC IDENTIFICATION Russian patent published in 2024 - IPC G06F21/32 G06V40/16 G06V40/40 

FIELD: data processing.

SUBSTANCE: invention relates to a method, a terminal and a system for biometric identification. Method comprises steps of: activating, in a terminal for biometric identification, a human face search mode on color images obtained from a video stream from one camera from a stereo camera; detecting and tracking a person's face in an image from said one camera from a stereo camera and determining its dimensions and coordinates; searching for a person's face in an image from an infrared or thermal camera, synchronized with said image from a color camera, and determining its dimensions and coordinates; comparing the dimensions and coordinates of the person's face, determined for the image from the color camera and for the image from the infrared or thermal camera, and making a conclusion on the presence of a person in front of said cameras based on said comparison; sending images from stereo camera and infrared or thermal camera to recognition server; presence of a living person on a captured image is checked on a recognition server by analyzing a color image from one camera from a stereo camera and when confirming the presence of a living person on the captured image, the person's face is recognized, which includes steps of, on which face images of a person on said images received from the terminal are compared with templates stored in a database, and a conclusion is made regarding the presence or absence of a match with the template; and sending the person recognition results from the recognition server to the terminal.

EFFECT: high reliability of identification.
