A reception interface (121) is configured to receive first authentication information related to first contactless authentication for authenticating a user and second authentication information related to second contactless authentication for authenticating the user in a different manner from the first contactless authentication. A processor (122) is configured to determine whether the first contactless authentication and the second contactless authentication are respectively approved based on the first authentication information and the second authentication information, and to control operation of a controlled device (21) in a case where it is determined that both the first contactless authentication and the second contactless authentication are approved.

A face authentication apparatus (50) includes an image generation unit (102) that generates a first image by capturing an image of a person, a control unit (104) that, when the first image does not satisfy a criterion for face collation, controls lighting and causes the image generation unit (102) to generate a second image by capturing an image of the person again, and a face authentication unit (52) that executes face authentication by using the second image.

An information processing device includes: an acquisition unit that acquires a first image by capturing a subject at a first distance, and extracting, from a registered biological information group that includes biological information of a plurality of registrants, a first biological information group that contains biological information of a first person detected from the first image; and a collation unit that collates biological information of a second person detected from a second image obtained by capturing the subject at a second distance, which is shorter than the distance to the subject in the first image with the biological information included in the first biological information group.

An electronic apparatus includes: control means for performing control to record, in recording means, characteristic data on a line-of-sight; authentication means for authenticating a user; and detection means for detecting, in a case where characteristic data on a line-of-sight of the authenticated user is recorded in the recording means, a line-of-sight of the user by using the recorded characteristic data on the line-of-sight.

An authentication method for a computer to execute a process includes referring to a memory that stores biometric information of a person associated with feature information of a face image of the person; specifying a first biometric information group and a second biometric information group; specifying one selected from the first biometric information group and the second biometric information group, based on a similarity between feature information of a third face image included in third imaged data and each of the feature information of the first face image and the feature information of the second face image; and executing authentication processing according to a plurality of pieces of biometric information included in the specified biometric information group and the acquired biometric information.

A control method for a watercraft is used for the watercraft including a device that requires authentication of identification information for activation, and has reading processing, authentication processing, and activation permission processing. In the reading processing, the identification information is read by each of plural reading sections, each of which is mounted on a hull of the watercraft and can read the identification information. In the authentication processing, the identification information, which is read in the reading processing, is authenticated by referring to authentication information. In the activation permission processing, in the case where the identification information that is read by any one of the plural reading sections is successfully authenticated, the device is brought into an activatable state.
