Biometric authentication device, authentication accuracy evaluation device and biometric authentication method |
摘要 |
A biometric authentication device includes a verification-image generation probability calculation unit for calculating a verification-image generation probability using a verification-image generation probability model, a change probability calculation unit for calculating a change probability of a set of a registration image and a verification image using a change probability model, a dissimilarity calculation unit for calculating the degree of dissimilarity on the basis of the verification-image generation probability and the change probability and an authentication unit for determining whether the verification image belongs to an authentication target by comparing the degree of dissimilarity with a predetermined authentication threshold.
