An image taking device with a lighting device includes a light irradiating portion for irradiating light to a subject and a light receiving portion for receiving reflected light from the subject that is irradiated by the light. The light irradiating portion is structured to have a plurality of light sources that are arranged so as to surround the light receiving portion. Each of the light sources is adjusted to emit light of an intensity corresponding to an arrangement position.

Disclosed is an authentication apparatus easily achieving convenience and high accuracy in authentication. The authentication apparatus has an authentication accuracy simulation section that simulates authentication accuracy and also has a registration information setting section that sets an ID and biometric information input as registration information. The authentication accuracy simulation section uses an ID and biometric information that has been input as registration information by a user at the time of registration and the registered registration information to simulate authentication accuracy with which the user is authenticated. When the authentication accuracy simulated by the authentication accuracy simulation section does not satisfy a predetermined condition, the registration information setting section rejects registration of the ID input as the registration information.

A biometric authentication apparatus includes an image shooting unit to capture a vessel image of a person to be authenticated and an authentication unit to verify verification vessel position information of the captured vessel image of the person to be authenticated against registered vessel position information of a registered vessel image registered in advance. When the verification vessel position information is not identical with the registered vessel position information, the authentication unit performs authentication using vessel size information of the registered vessel image registered in advance.
