ABSTRACT:
The present invention provides to output, in a shortest possible time, a comparison result of a “dactylogram of paper” in a system for assuring being original paper of a “dactylogram of paper”, with accuracy. A scanned image data of a paper document is obtained, while pre-stored dactylogram data for the paper is acquired. Between two image data of n-th region cut out from the scanned data and the stored image data respectively, the degree of similarity is calculated If the degree for a first region is a value C1or more, it is determined that the both side matches. If the degree is less than a value C2that is smaller than the C1, the both side are determined to mismatch each other. If the degree is less than the C1and is the C2or more, then comparison for a second region performed to determine whether matching or not.
