Abstract: The image acquisition unit acquires a body image generated by capturing an image of a body of a target person when a target person is in a position away from an imaging unit by a first distance and acquires a code image generated by capturing an image of a code recording medium carried by the target person when the target person is in a position away from the imaging unit by a second distance shorter than the first distance. The authentication information generation unit starts processing for generating biometric information for authentication of the target person from the body image in accordance with the acquisition of the body image of the target person. The embedded information acquisition unit acquires embedded information from the code image. The authentication unit executes biometric authentication by collating biometric information for authentication with biometric information for registration included in the embedded information.
