<P>PROBLEM TO BE SOLVED: To suppress information leakage by a flexible monitoring method according to the characteristics of an image or document. <P>SOLUTION: A job analysis section 113 analyzes a print job, and separates image data and attribute information. An image generation section 116 generates print image data from the image data by referring to the attribute information. A digital watermark generation section 121 and a synthesis section 118 embed at least part of the attribute information in the print image data. An image transmission section 122 transmits, to a monitoring server 103, the print image data with at least part of the attribute information added thereto. A monitoring method selection section 120 selectively operates the digital watermark generation section 121 and the synthesis section 118 or the image transmission section 122 based on the attribute information. <P>COPYRIGHT: (C)2008,JPO&INPIT |
