摘要： A biometric authentication method is disclosed. Biometric information is acquired from a pair of portions at right and left of a body. Collation feature data are generated from the biometric information for right and left. Similarity feature data are generated for calculating a similarity between the biometric information for right and left. A similarity score between right and left is calculated by using the similarity feature data. The collation feature data for right and left and the similarity score are registered in a registration database. Collation scores for right and left are calculated by comparing the collation feature data in the registration database, and other collation feature data generated in an authentication. It is determined whether the authentication is successful, by using the collation scores, the similarity score in the registration database, and another similarity score generated in the authentication.

摘要： A sensor acquires the same type of biometric information from plural fingers in association with an ID. A processor generates feature data used for verification from the biometric information, and generates characteristic data used for calculation of similarity between the plural fingers from the biometric information. Next, the processor compares the characteristic data and calculates the similarity between the plural fingers. The processor determines whether the feature data is registrable based on the similarity, and a memory stores the feature data in association with the ID when the feature data is registrable.
