US 2022/0188556 A1 · METHOD AND APPARATUS THAT DETECTS SPOOFING OF BIOMETRIC INFORMATION

Abstract

A method and apparatus that detects whether biometric information is spoofed is provided. The method receives, from a sensor, first feature information including a static feature associated with biometric information of a user, and a dynamic feature obtained based on images related to the biometric information, detects whether the biometric information is spoofed based on a first score calculated based on the first feature information, fuses the first score with a second score calculated based on second feature information extracted from the images, based on a result of the detecting that the biometric information is spoofed based on the first score, and detects that the biometric information is spoofed based on a fused score.

Dependent claims

A biometric information spoofing detection method, the method comprising:

receiving, from a sensor, first feature information including a static feature associated with biometric information of a user, and a dynamic feature obtained based on images associated with the biometric information;
determining whether the biometric information is spoofed based on a first score calculated from the first feature information;
fusing the calculated first score with a second score calculated from second feature information extracted from the images, based on a result of the determining whether the biometric information is spoofed based on the first score;
and
determining that the biometric information is spoofed based on the fused first score and second score.

2 more elements

An apparatus that detects whether biometric information is spoofed, the apparatus comprising:

a sensor, configured to sense biometric information of a user;
a communication interface, configured to receive, from the sensor, a static feature associated with the biometric information of the user, and images associated with the biometric information of the user;
and
a processor, configured to:
receive first feature information including the static feature, and a dynamic feature obtained based on the images,
determine whether the biometric information is spoofed based on a first score calculated based on the first feature information,
fuse the calculated first score with a second score calculated based on second feature information extracted from the images to obtain a fused score, based on a result of the determining that the biometric information is spoofed based on the first score, and
determine that the biometric information is spoofed based on the fused first score and the second score.
