Abstract: <P>PROBLEM TO BE SOLVED: To certify that an image is authentic and to prevent forgery.  <P>SOLUTION: A printer for processing an image to be outputted generates a random dot image having dots arranged at random (S10 to S12) and operates exclusive OR between corresponding pixels of the generated random dot image and a preliminarily prepared first mask image 32 per pixel to generate a cipher image (S13). The generated random dot image and the cipher image are processed by geometric transformation or the like so that corresponding pixels coincide with each other when both images are printed out while both are superposed (S15). When they are outputted in a superposed state, the first mask image 32 embedded in the cipher image visually appears through the random dot image because of exclusive OR operation. Only the image which has the first mask image visually recognized is certified as authentic. Since the precision of this superposition can not be obtained in ordinary copying machines, forgery is prevented.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
