Abstract: A vein authentication device converts pixel values of an image, which captures an authentication site including veins, into frequency components. Moreover, the vein authentication device performs filtering of the frequency components, which are obtained by conversion of the pixel values, using a filter stored in a filter storing unit for reducing frequency components, from among low-frequency components having a lower spatial frequency than the spatial frequency of the veins and high-frequency components having a higher spatial frequency than the spatial frequency of the veins, corresponding to surface reflection of an illumination used for the authentication site. Furthermore, the vein authentication device converts the frequency components, which are subjected to filtering, back into an image. Moreover, the vein authentication device extracts vein data representing a vascular pattern of veins from the image obtained by reverse conversion.

Abstract: Disclosed is an authentication apparatus easily achieving convenience and high accuracy in authentication. The authentication apparatus has an authentication accuracy simulation section that simulates authentication accuracy and also has a registration information setting section that sets an ID and biometric information input as registration information. The authentication accuracy simulation section uses an ID and biometric information that has been input as registration information by a user at the time of registration and the registered registration information to simulate authentication accuracy with which the user is authenticated. When the authentication accuracy simulated by the authentication accuracy simulation section does not satisfy a predetermined condition, the registration information setting section rejects registration of the ID input as the registration information.
