ABSTRACT:
An image processing apparatus which stores user information related to a seller or a buyer of the image processing apparatus. The user information is thereafter multiplexed to an output image formed by the image processing apparatus. If the output image were an unlawful image, the seller or the buyer could be identified from the user information multiplexed in the output image.
