Problems solved by technology

Therefore, the copying of the original document may be illegally performed, and even when an image is attached to the surface of the original document for the purpose of restricting copying, there is a problem that information leakage may occur.
[0007] In addition, in the case of using ink with optical or magnetic characteristics, in order to detect the image formed with the ink, a detection device different from the document reading device is required, and there is a problem of increasing the cost of the entire device.
In addition, since special ink is used, there is a problem that ink is not easily available in terms of device management, and there is a problem that the maintenance cost of ink is further increased.
[0008] Furthermore, when a specific pattern such as a barcode, ink with predetermined characteristics, etc. are detected and the copying operation is stopped, even a person with legal authority such as the maker of the confidential document cannot copy the confidential document. In the case of duplicating confidential documents, it is necessary to output images on the printer again, and there is a problem that the handling of confidential documents is very troublesome

Embodiment approach 1

[0101] FIG. 1 is a block diagram illustrating the configuration of an image forming system according to the present embodiment. In the figure, 100 is a compound machine, and the compound machine has: a scanning function, which reads an image of a document; a copying function, which forms an image on a sheet such as copy paper or OHP film (hereinafter referred to as paper) based on the read image; A printing function that receives print data sent from outside to form an image on paper; a filing function that temporarily saves input image data; and an image sending function that sends image data to the outside, and the like. Information processing devices 200 and 200 such as personal computers are connected to the multifunction peripheral 100 via a local area network LN, and an information processing device 300 is connected via the Internet IN. In addition, an external facsimile device 400 is connected via a public telephone network PN.

Embodiment approach 2

[0147] In Embodiment 1, the multifunction peripheral 100 provided specific information when the user himself designated a confidential file through the printer driver, but specific information may be provided when it is determined that the received print data is data sent from a specific user. . In this embodiment, the configuration of the image forming system and the internal configuration of the multifunction peripheral 100 are the same as those of Embodiment 1, and therefore description thereof will be omitted.

[0148] Figure 8It is a flowchart illustrating the procedure of processing executed by the image forming system of the present embodiment. The control unit 101 of the multifunction peripheral 100 monitors the communication IF 106 to determine whether or not print data transmitted from the information processing device 200 has been received (step S61 ). When it is judged that the print data has not been received (S61: NO), it waits until the print data is received...

Embodiment approach 3

[0154] In Embodiment 2, when it is determined that the received print data is sent from a specific user, specific information is added to the back of the paper, but the specific information may be included in the image developed from the received print data. Specific information is given in the case of the image.

[0155] Figure 9 It is a flowchart illustrating the procedure of processing executed by the image forming system of the present embodiment. The control unit 101 of the multifunction peripheral 100 monitors the communication IF 106 to determine whether or not print data transmitted from the information processing device 200 has been received (step S81 ). When it is determined that the print data has not been received (S81: NO), it waits until the print data is received. When it is determined that the print data has been received (S81: Yes), the received print data is developed (step S82), and the developed image data is held in the image memory 108.

Abstract

The present invention provides a image forming device and image reading device. An image forming apparatus receives image data and forming an image on a sheet based on the image data received, comprising a memory means for storing image data related to a fixed image and a judgment means for judging the presence or absence of the confidentiality of the received image data, and an image based on the image data and the fixed image are formed on one side and another side of a sheet respectively when it is judged that the image data have confidentiality.

Description

technical field [0001] The present invention relates to an image forming apparatus that attaches an image including information restricting copying when outputting a confidential document, and an image reading apparatus capable of restricting copying when reading a document to which the image is added. Background technique [0002] Conventionally, as a function of controlling a print driver of an image forming apparatus such as a printing apparatus and a multifunction printer from an information processing apparatus such as a personal computer, there is a function of writing a specific character string or a mark on each printed page or an arbitrary page (hereinafter referred to as A device that is a watermark function) has been commercialized in large quantities. This watermark function is used for the following purposes: To remind users of the processing of printed documents by writing characters such as "confidential", "important", "circulated", "urgent", and "copy prohibi...
