发明名称 Biometric authentication device, biometric authentication method, and computer readable, non-transitory medium
摘要 A biometric authentication device includes: a memory configured to store an enrollment feature data; a biometric sensor that obtains a biometric image of a user; and a circuitry configured to: obtain a surface reflection degree of the biometric image; extract a comparison-use feature data from the biometric image; perform a comparing based on a similarity between the comparison-use feature data and the enrollment feature data; and reflect a correction coefficient and the surface reflection degree related to a region of the biometric image to the similarity.

主权项 1. A biometric authentication device comprising: a memory configured to store an enrollment feature data; a biometric sensor that obtains a biometric image of a user; and a circuitry configured to: obtain a surface reflection degree of the biometric image; extract a comparison-use feature data from the biometric image; and perform a comparing based on a similarity between the comparison-use feature data and the enrollment feature data, the similarity being obtained by using a correction coefficient and the surface reflection degree related to a region of the biometric image, the correction coefficient being a weighting coefficient of the similarity.
