There is provided an image forming device that does not require an original image scanning operation upon copying of an original for the second time or later in a device for preventing illegal copying with the use of paper fingerprint information. Upon registration of the paper fingerprint information, original image data is scanned from the original. Also, the paper fingerprint information is scanned. The image forming device associates the original image data and the paper fingerprint information with each other to register them in an information processing device. Upon copying, paper fingerprint information scanned from an original is transmitted to the information processing device to request the device to determine whether or not the paper fingerprint information has been registered. If the paper fingerprint information has been registered is received, the original image data registered in association with the paper fingerprint information is retrieved from the information processing device.

Device for controlling image processing based on paper fingerprint

A multi CPU system is capable of performing exclusive control of a plurality of CPUs accessing to the same resource by a hardware without depending on an OS. The plurality of CPUs are connected with the same system bus. A plurality of circuits one-to-one correspond to each of the plurality of CPUs and comprise respective semaphore acquisition registers. Each of the CPUs in accessing to the resource is controlled, based on the value written in the semaphore acquisition register of the corresponding circuit, the presence or absence of the priority in the semaphore control, and a semaphore signal received from the another circuit.
