Abstract
A biometric authentication device includes a biometric information sensor to read biometric information of a user, a biometric information storage unit to pre-register biometric information of a registered person as registered biometric information for verification, a determination unit to determine whether or not a captured image captured by the biometric information sensor is suitable for biometric authentication, and to perform biometric authentication by comparing the captured image to the registered biometric information registered in the biometric information storage unit when the determination unit determines that the captured image is suitable for the biometric authentication, and a notification unit to issue a notification indicating that the captured image is unsuitable for the biometric authentication. When the determination unit determines that the captured image is unsuitable for the biometric authentication, the determination unit does not perform the biometric authentication by the authentication unit and causes the notification unit to issue the notification.
