Abstract
In an image forming system, a digital copying machine, which is requested to determine image data, stores determination history data including a result of determination in its memory when the result indicates that the image data are prohibited to be copied, and transfers the determination history data to a digital copying machine of a requesting end, and also transfers the determination history data automatically or as requested to other digital copying machine, a central image formation control unit or a host computer of the service center. As a result, an inhibit copy action can be prevented even when a digital copying machine being used within the system is not provided with an image determining function, thereby providing a security system which can inform others of an occurrence of an illegal or dishonest action at real time.
