In a verification apparatus, a biometric information acquisition unit acquires a plurality of biometric information pieces from an object. A first verification unit calculates, as a verification score, the similarity between the biometric information piece and a verification information piece, and compares the calculated verification score with a first determination value to determine whether the biometric information piece matches the verification information piece. When the verification fails, a second verification unit performs verification on the plurality of biometric information pieces having a predetermined relationship, using the verification information piece and a second determination value which defines a less stringent criterion than the first determination value. The second verification unit compares the verification score with the second determination value, and determines that the match is confirmed when a plurality of biometric information pieces satisfy the criterion defined by the second determination value. |
