An original signature can be verified even if a signed image data is properly altered in its portion. The digital image data is divided into a plurality of configurational elements, and each of the feature values of the elements are calculated, so that the signature is created by combining the feature values. In case the configurational elements are to be deleted, they are substituted by substitutive data, and only the feature values are stored. The verification is created by using the stored feature values as the substituted elements and by using the calculated feature values as the remaining elements, so that the signature is verified with the signature attached to the digital image data.
