  • Patent number: 12530441
    Abstract: High-accuracy multimodal biometric authentication of a plurality of body organisms is achieved while suppressing postural fluctuation when the plurality of body organisms are captured. An authentication system stores feature quantities for body organisms in association with users and performs biometric authentication on the basis of images from a capture device. The capture device photographs a first body organism of a first user during a first period and captures a second body organism and a third body organism of the first user during a second period. The authentication processing device calculates a first feature quantity from the first body part photographed during the first period, respectively calculates a second feature quantity and a third feature quantity from the second body organism and the third body organism captured during the second period, and compares with the feature quantities for the body organisms of each user stored at the storage device.
