Claim Text:
1. An authentication apparatus, comprising: one or more processors configured to perform a procedure including: correcting surface information on a living body surface extracted from image information obtained by photographing a living body; and performing biometric authentication using the corrected surface information, wherein the correcting the surface information includes: wherein the surface information allows concavity/convexity of the living body surface to be evaluated, wherein the one or more processors further perform a procedure including: extracting, from the image information, luminance information as the surface information that allows the concavity/convexity of the living body surface to be evaluated; and identifying, from the surface information, a range and brightness of a concave/convex part of the living body surface to determine whether or not the range and a degree of the brightness of the concave/convex part of the living body surface are within a correctable predetermined range, and wherein the correcting the surface information is performed by correcting the concavity/convexity of the living body surface for the surface information.
