    摘要： A computer accepts biometric information to be authenticated detected by a first sensor. In a case where one or more persons are detected by a second sensor at the time of detection of the biometric information to be authenticated, the computer specifies one person included in the one or more persons on the basis of a movement of each of the one or more persons. The computer selects registered biometric information associated with registered face image information similar to face image information of the specified one person, from among a pieces of the registered biometric information respectively associated with a plurality of pieces of registered face image information. The computer authenticates the biometric information to be authenticated on the basis of a comparison result of comparing the biometric information to be authenticated with the selected registered biometric information.

    摘要： In an authentication method, a computer executes a process including: obtaining a captured image captured by a camera; selecting one facial image from a plurality of facial images based on a position of each of the plurality of facial images included in the obtained captured image in the captured image; referring to a storage unit that stores pieces of biometric information associated with the respective plurality of facial images and specifying a piece of the biometric information associated with a facial image in which a degree of similarity to the selected facial image satisfies a criterion; and performing, when biometric information detected by a sensor is received, authentication based on verification of the specified piece of the biometric information against the received biometric information.

    摘要： A computer accepts biometric information to be authenticated detected by a biometric sensor. The computer specifies a face image of any one of persons included in a captured image on the basis of an orientation of a line of sight or an orientation of a face of one or more persons appearing in the captured image captured by an imaging device at the time of detecting the biometric information to be authenticated. The computer selects registered biometric information associated with registered face image information similar to the specified face image from among pieces of registered biometric information respectively associated with a plurality of pieces of registered face image information. The computer authenticates the biometric information to be authenticated on the basis of a comparison result of comparing the biometric information to be authenticated with the selected registered biometric information.

    摘要： A biometric authentication apparatus includes a storage unit which stores first shape data representing a shape of biometric information of a registered user's hand with fingers at a first posture, a first index representing the first posture, second shape data representing a shape of biometric information of the hand with the fingers at a second posture, and a second index representing the second posture; a posture specification unit which calculates a third index representing a third posture of fingers of a user's hand captured in biometric image; a biometric information extraction unit which generates third shape data representing a shape of biometric information of the user's hand captured in the biometric image; a correction unit which obtains corrected shape data by correcting the first or the second shape data to cancel a shape difference of the biometric information due to a difference between the third posture and the first or the second posture according to a ratio of a difference between the third index and the first or the second index to a difference between the first and the second indexes; and a matching unit which matches the third shape data and the corrected shape data.
