PROBLEM TO BE SOLVED: To provide an image processor capable of improving the secrecy of image data by preventing the image data from being illegally taken out. SOLUTION: A document ID generated by an image managing means 103 is converted into a scramble document ID, which corresponds to the document ID but is not logically sequential, a code for display and/or code for ID mark is outputted based on the scramble document ID, the image data are composed of an ID mark and/or code for display generated based on the code for ID mark, and they are outputted by an image output means 109. Therefore, since the scramble document ID can be used for the code for display, the image data can be prevented from being illegally taken out by estimating the code for display of the other image data from the code for display. |
