<P>PROBLEM TO BE SOLVED: To suppress unauthorized use of a secrete document by making it possible to judge an image processor outputted image data from the outputted image data. <P>SOLUTION: The image processor 1003 prints out at least one of arbitrary information indicative of the information of the image processor itself or a user, or the information of destination route while embedding in original image data, or transmits the arbitrary information to a client device 1001 when the image data is outputted. The arbitrary information being embedded may be visible data such as a character string or a bar code but it is preferably watermarked in order to protect the information against alteration or destruction. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
