PROBLEM TO BE SOLVED: To obtain a security system in which even a digital copying machine without an image discrimination function prevents an illegal copying act and an illegal image processing act as to a copy inhibit original set by the user and is able to inform the illegal act to others. SOLUTION: A digital copying machine receiving a request for image processing, the machine sends the image requested for processing to a copying machine having an image discrimination function (S82). When the copying machine receiving the discrimination request discriminates it that the image processing is to be applied to a copy-inhibited image, the copying machine stores discrimination history information, including a discrimination result to a memory and returns the discrimination result to the digital copying machine which is the request source machine (S83). The digital copying machine being the request destination or the digital copying machine being the request source transfers the discrimination history information, in response to a transfer request of the discrimination history information from other digital copying machine, a central image-forming forming management equipment or a host computer of a service center or automatically (S97, S98). |
