<p>An IC card on which registration signature data are recorded is used for a signature authenticating system. For dissimilarity of verification signature data, there are provided three ranks defined by a first parameter and a second parameter greater than the first parameter. If the measured dissimilarity falls within the rank below the first parameter, the signature is authenticated; if the measured dissimilarity falls within the second rank above the first parameter and below the second parameter, re-signature is ordered, and authentication is denied after a specified number of re-signatures each yield a similar result; and if the measured dissimilarity falls within the rank above the second parameter, authentication is denied. <IMAGE></p> |
