    摘要： The purpose of the present invention is to provide a highly accurate authentication system in a biometric authentication system. The authentication system includes: a measurement device that acquires biometric modality information from a living body of a first user; an input unit that generates at least one item of input information from the biometric modality information; a storage device that stores first feature information acquired from the biometric modality information of the first user, and second feature information acquired based on a correlation between the biometric modality information of the first user and biometric modality information of a second user; and an authentication unit that authenticates the first user by collating the input information with the first feature information and collating the input information with the second feature information.

    摘要： In the conventional art, there has been a problem that it is difficult to perform, with a high usability and at a high precision, authentication that accepts a wide range of variation of showing attitude of a hand or a finger and ensures obtaining a clear blood-vessel image of a finger. Provided is a blood-vessel image capturing apparatus including an opening portion formed in a surface of a housing, plural light sources disposed beside the opening portion and arranged in a lattice pattern, a sensor configured to obtain position information of a hand shown above the opening portion, a light amount control portion configured to select an irradiation light source to irradiate the hand from the plural light sources on a basis of the position information and control a light amount of the irradiation light source, and an image capturing portion configured to capture an image of a blood vessel included in a finger portion of the hand irradiated with light from the irradiation light source.
