1. A biometric authentication method comprising:
acquiring, by a computer, sets of biometric information for right and left from a pair of portions at right and left of a body; generating, by the computer, sets of collation feature data to use for a collation from the sets of the biometric information for right and left; generating, by the computer, sets of similarity feature data to use for calculating a similarity between the sets of the biometric information for right and left from the sets of the biometric information for right and left; calculating, by the computer, a similarity score representing the similarity between the sets of the biometric information for right and left by comparing the generated sets of the similarity feature data for right and left with each other; registering, by the computer, the sets of the collation feature data for right and left and the similarity score by associating with each other in a registration database; calculating, by the computer, collation scores for right and left respectively by comparing the sets of the collation feature data registered in the registration database, and other sets of the collation feature data for right and left generated from other sets of the biometric information for right and left in an authentication; and determining, by the computer, whether the authentication is successful, by using the collation scores for right and left, the similarity score in the registration database, and another similarity score acquired by comparing other sets of the similarity feature data for right and left generated from other sets of the biometric information acquired in the authentication. |
