<P>PROBLEM TO BE SOLVED: To provide a copying management system by which a copying operation is flexibly managed to prevent or detect information leakage caused by the copying operation. <P>SOLUTION: In this copying management system, an output device (10) is provided with: a list information generation part (102) for generating list information including specification information to specify a person who is permitted to make a copy or the like; a print image generation part (101) for generating a print image; and an embedding part (104) for converting the list information into a specific code, and for embedding it in the print image, and for generating an embedded print image. A copying device (30) is provided with a copying specification information accepting part (205) for accepting the input of the copying specification information to specify a person who makes a copy or the like; a list information acquisition part (203) for acquiring list information from the embedded print image; a copying determination part (204) for comparing the specification information included in the list information with the copying specification information, and for determining either the permission or inhibition of copying; and a copying part (202) for performing copying when copying is permitted. <P>COPYRIGHT: (C)2008,JPO&INPIT |
