PROBLEM TO BE SOLVED: To specify the alteration place of image data in which text information is mentioned.;SOLUTION: Character recognition processing is executed to image data in which text information is mentioned, and electronic signature is applied to the character recognition result and the image data. The electronic signature is applied to data obtained by connecting the featured values of the character recognition result with the featured values of the image data. At the time of specifying the alternation place, the verification of the electronic signature and character recognition processing to the image data is executed, and the featured values of the result of the character recognition are calculated, and compared with the featured values of the stored character recognition result so that the place where the both featured values are not matched is specified as the alternation place.;COPYRIGHT: (C)2006,JPO&NCIPI
