Patent ID: 7701598

Claim:
An image forming device, comprising: an output control unit which prohibits output by the image forming device if specific image data is detected in image data of an original document that is read; a current data acquisition unit which acquires current data corresponding to a time at which output is prohibited by the output control unit; a password creating unit which creates a password in accordance with the current data acquired by the current data acquisition unit; a transmit/receive unit which transmits image data which is prohibited from being output by the output control unit and receives output permission/prohibition data from an administrator; an identification unit which identifies the output permission/prohibition data received by the transmit/receive unit; an output permitted image generating unit which generates an output permitted image in which the password created by the password creating unit is embedded such that it is impossible for a user to identify the password, the output permitted image generating unit generating the output permitted image if the output permission data is identified by the identification unit; an output unit which outputs the output permitted image generated by the output permitted image generating unit; a reading unit which reads the output permitted image output by the output unit; an extraction unit which extracts password data embedded in the output permitted image data which is read by the reading unit; and a determination unit which determines whether or not the password extracted by the extraction unit and the password created by the password creating unit correspond to each other; wherein the output control unit will lift a prohibition on output if the determination unit determines that the passwords correspond to each other.
