Embodiment Construction

[0039] Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0040] figure 1 is a block diagram showing the internal functional structure of the image processing apparatus according to the present invention. The image processing apparatus 1 is equipped with a control section 101 including a CPU that performs operations and a RAM that temporarily stores information related to operations. A ROM 105 storing a control program for controlling the image processing apparatus 1 is connected to the control section 101 . The control section 101 controls the entire image processing apparatus 1 according to a control program stored in the ROM 105 . Further, a management section 104 is connected to the control section 101 , and the management section 104 is a memory that stores management information for managing processing performed by the image processing apparatus 1 . The control section 101 refers to the ma...

Abstract

An image processing device that determines whether any processing according to information received from an external device should be performed based on an IP address received from the external device. Check the communication path with the external device from the network address. When the external device as the transmission source of the information is an external device outside a predetermined range, specifically, for example, when the external device is an external device connected to a communication network other than the communication network connected to the image processing device, the The image processing device prohibits any processing in accordance with the image data processing command received from the external device. The image processing device also inhibits any processing in accordance with a command to adjust the image processing device received from outside the predetermined range.

Description

technical field [0001] The present invention relates to an image processing apparatus capable of protecting image data from unauthorized use. Background technique [0002] Recently, an image processing apparatus having a copying function of scanning an image recorded on paper to capture image data and forming and outputting an image based on the captured image data has become multifunctional. An image processing apparatus having various functions other than a copying function, such as a network printer, which, while being connected to a communication network such as a LAN, has been put into practical use from a computer such as a personal computer (PC). An external device receives image data to output an image; a facsimile function in which image data is sent and received by facsimile communication using an external facsimile device; and a transmission function in which captured image data is sent to an external device. In order to perform image data processing in each func...
