| 主权项 | 1. A biometric authentication device comprising: a biometric sensor that obtains biometric information; a memory; and a circuitry configured to: select an objective user according to density of distribution of registered part data within a predetermined range in a set of the registered part data, the predetermined range including a comparison-use part data that is a part of a comparison-use feature data extracted from the biometric information, the registered part data being a part of a registered feature data; and perform comparing between a registered feature data of a selected objective user and the comparison-use feature data. | ||
