Description

  The present invention relates to an image processing apparatus, and more particularly, to an image processing apparatus capable of adding specific image information for prohibiting or suppressing copying of image data.

In order to prevent unauthorized copying of a printed document, a method of giving specific image information such as a background pattern when the document is printed is used. This specific image information is also called copy control information or anti-copy information.
For example, when image data is sent from an application running on a PC or the like to a printer and the image data is printed out by the printer, specific image information for restraining copying of the print image is sent to the printer together with the image data. The printer embeds the specific image information somewhere in the print image and prints it out.
Then, if the print image in which the specific image information is embedded is to be copied using a copying machine, the copy machine that detects the specific image information may not output the copy print or may be “copy prohibited”. Such as printing and outputting characters such as.

The specific image information as described above may be embedded in the print image in a shape that cannot be identified by the user, or may be embedded in the print image in a shape that allows the user to identify the specific image information.
However, in any case, when the copying machine copies the image information in which the specific image information is embedded, the copying machine detects that the specific image information exists in the image information, and according to the detection result, A predetermined process, for example, a process of stopping the copy itself as described above or outputting a copy image with characters such as “copy prohibited” is performed.

  With regard to the technology for prohibiting copying as described above, for example, Patent Document 1 discloses a copying machine that can easily create a document with a specific pattern added thereto. Here, the copying machine includes a specific mark generating means for adding a specific mark to an original image and reproducing the image, a mark presence / absence detecting means for detecting the presence / absence of the specific mark in the read original image, and the presence / absence of the mark. Control means is provided for making the copying operation different from normal when the detection means detects a specific mark in the document image.

Further, Patent Document 2 discloses a copying machine that can obtain a reproduced image that can easily and accurately detect a specific mark. Here, in a copying machine having a function of reproducing an image with a specific mark added by the mark adding means, the mark adding means adds a specific mark composed of a plurality of concentric circles having different diameters to the document image. Yes.

I do.

  FIG. 2 is a diagram for explaining a configuration example of an image forming apparatus to which the image processing apparatus of the present invention can be applied. In this example, the scanner device 130 is provided with a determination unit 132 that determines whether or not the specific image information is included in the image data when the scanner device reads the recording material on which the specific image information is recorded.

  In this example, the scanner device 130 includes an image reading unit 131 that reads an image recorded on a recording sheet or the like, and a determination unit 132 that determines whether the image data read by the image reading unit 131 includes specific image information. And an operation unit 133 that accepts an operation input by a user or an input of an authentication code, and a sub CPU 134 that controls each element of the scanner device 130.

  The printer board 121 of the printer 120 communicates with an external device such as a PC via a network such as a LAN. The image processing unit 122 performs image processing on image data input from an external device via the printer board 121 or image data read by the scanner device 130 and stores the image data in the image memory 123. Here, the image processing unit 122 develops the input image data, and stores it in the image memory as print execution data. Further, the image processing unit 122 adds the specific image information added by the specific image information adding unit 125 to the image data to generate print execution data. The image recording unit 124 uses the print execution data recorded and held in the image memory 123 to form an image on a recording sheet or the like.

The specific image management unit 126 manages specific image information added to the image data. Here, storage means for storing specific image information in a predetermined form is provided. The specific image information adding unit 125 adds the specific image information in a predetermined form to the image data formed by the image recording unit 124 in accordance with a predetermined specific image information addition condition. To instruct. The management unit 127 is a memory that stores management information (various control information) for managing processing performed by the printer 120. The main control unit 128 controls the operation of each element.
The printer 120 shown in FIG. 2 may be a multi-function machine including the scanner device 130 or may be interconnected so as to be able to transfer data with a separate scanner device 130.

  The printer 120 having the above-described configuration is predetermined when the image recording unit 124 forms an image of image data read by the scanner device 130 or image data input from an external device via the printer board 121. The specific image information is added to the image data corresponding to the addition condition according to the addition condition of the specific image information. The specific image information added to the image data is managed by the specific image management unit 126 as described above, sent to the image processing unit 122 by the specific image information adding unit 125, and added to the target image data by the image processing unit 122. Is done.

  When the determination unit of the scanner device 130 determines that the specific image information is included in the image data read by the image reading unit 131, the sub CPU 134 of the scanner device 130 determines the determination to the main control unit 128 of the printer 120. Send the result. The main control unit 128 performs control for prohibiting copying of the image data (prohibiting image formation in the image recording unit 124) according to the transmitted determination.

  FIG. 3 is a diagram showing an example of specific image information applicable to the present invention, in which 20 is specific image information. The specific image information 20 can be configured as a graphic in which a plurality of dots are arranged as shown in FIG. 3, for example. When the copying machine detects the specific image information 20, the copying machine prohibits copying itself, or adds warning information to the image information to warn the user that copying is prohibited or restricted. Is output. For example, as warning information, a character “copy prohibited” can be printed, or a character “mihon” can be printed on a copy prohibited image such as a banknote.

FIG. 4 is a diagram illustrating an example of arrangement of specific image information on a recording sheet. Here, the specific image information 20 having a shape as shown in FIG. 3 is used, and the specific image information 20 is printed out in the vicinity of the inside of the four sides around the recording paper 30. When a recorded material on which such specific image information 20 is printed is to be copied, the copying machine recognizes the printed specific image information 20 and performs a copy prohibition process. Note that the shape and arrangement of the specific image information 20 are merely examples, and these can be determined as appropriate.
The image processing apparatus adds predetermined specific image information to the image data in a predetermined form in accordance with predetermined specific image information addition conditions. At this time, the specific image information addition condition allows the specific image information addition form to be individually set according to the characteristics (addition condition item) of the image data.

  FIG. 5 is a diagram for explaining a processing example when the specific image information addition condition is set in the image processing apparatus. Here, it is assumed that the setting condition setting authority when adding the specific image information to the image data is given only to an administrator of the image processing apparatus, for example. When setting the additional condition in the image processing apparatus, the image processing apparatus first requests authentication of the administrator (step S1). In this case, for example, when an additional condition setting request is input to the operation unit 102 of the digital multifunction peripheral 10 in FIG. 1, the device control unit 104 of the image processing apparatus inputs administrator information (administrator authentication code). The request is displayed on the display unit 102b.

  When administrator information is input for the display (step S2), the image processing apparatus determines whether authentication of the administrator information is OK (step S3). If the authentication is NG (impossible). The manager information is requested again (step S6), and the process returns to step S2. If the authentication is OK in step S3, an additional condition is set based on the operation of the administrator (step S4). In step S5, when the additional condition setting is completed, the additional condition setting process is terminated.

  FIG. 6 is a diagram for explaining a setting example of the specific image information addition condition, and shows an example of a display screen displayed by the image processing apparatus when the additional condition is set. In the example shown in FIG. 6, “IP address A”, “IP address B”, “copy”, “FAX”, “printer”, “confidential print”, “Hold Print”, “With Document Filing Password”, and “No Document Filing Password” are set in advance, and “Level” level can be set for each item. “Level” basically refers to the confidential level of image data, and the form of specific image information can be individually set according to the confidential level.

  In the above item, two types of “IP address” are set so that the security level can be set in two stages according to the user of the computer connected to the Internet or an intranet, for example. For example, it is possible to set such that a manager of a company sets a high level with “IP address A” and other employees set “IP address B” to a medium level. In addition, the level may be set according to user authentication information input by another user.

  As for “copy”, “FAX”, and “printer”, when image data is input using these devices or unit units, the level can be set according to each device or unit. I have to.

  “Secret print” and “hold print” are for setting a level when a specific highly confidential print output is performed. For example, some printing apparatuses (printers) such as copying machines are provided with a print output function in consideration of confidentiality called confidential printing or confidential printing. Confidential prints and hold prints are sometimes collectively referred to as confidential prints.

  In “Secure Print”, for example, when image data is sent from a PC or the like to a printer and printing is performed, the fact that the print is confidential and a password for the print are transferred from the PC to the printer, and then the print data is further transferred to the printer. Transfer them and store them in the memory of the printer. Then, the user recognizes the password on the display screen of the PC, goes to the printer and inputs the password, so that the printer starts print output. Here, depending on the memory environment on the printer side, the print data is held on the PC side, and when a password is input to the printer, the print data is transferred from the PC to the printer for printing.

  “Confidential print” is intended to print output that is inherently highly confidential, and the level is set high. In this case as well, the administrator can arbitrarily set the “confidential print” level. is there.

  “Hold print” is applied when document management is not performed with a password as in the above-described confidential print, but confidentiality is required. Here, image data transferred from a PC or the like is stored in a printer without being printed out as it is, and when the user goes to the printer and inputs an instruction to output desired print data, the print data is printed. It has become so. Here, the level can also be set for “hold printing”.

  Next, “document filing” stores, for example, image data read by an image reading unit (scanner device) or image data transmitted from an external device such as a PC in a printer memory (HDD or the like). With the function, the accumulated image data is transmitted not only to image formation in the image forming unit of the printer, but also to stored image data transmitted to an external device designated according to an operation input to the operation unit, or from an external device such as a PC The stored image data can be transmitted according to the transmission request.

  Here, in the document filing function, both a highly confidential filing function with a password and a filing function without a password can be set, and a level can be set for each.

  FIG. 7 is a diagram showing an example of a table that determines the addition form of the specific image information added to the image data with respect to the set value of the specific image information addition condition set in FIG. As shown in FIG. 7, a mode of adding specific image information to image data is set according to the level of the additional condition.

  The level designated here refers to a level determined corresponding to the setting item of the additional condition shown in FIG. 6, and is classified into a case where the level is high and a case where the level is low. For example, when the level is high, five pieces of specific image information are added, and the addition position of the specific image information is set to the center of the image data (the center when recording on the recording material), and the specific image information is printed darker. Is set to On the other hand, when the level is low, the number of specific image information to be added is one, and the addition position is the end of the image data (the end when recording on a recording material), and further the specific image information. Is set to print lightly.

  In this case, the addition form of the specific image information is set according to the level of detection accuracy when the specific image information is detected. For example, when the confidential level of image data is high, the copying machine needs to reliably detect the specific image information when copying a recording material to which the specific image information is added. Therefore, when the security level is high, the number of specific image information is increased, the specific image information is printed at the center instead of the edge of the recording paper, and the specific image information is printed darkly. Set.

  As described above, condition setting items to which specific image information is added, and a security level can be set for each condition setting item. When image data is actually formed, addition of predetermined specific image information is performed. Specific image information can be added according to the level of image data according to the form.

Further, the condition for adding the specific image information is not limited to the example of FIG. 6, and it is possible to set the condition items as appropriate, and the setting of the addition mode of the specific image information according to the level is also as shown in FIG. It can be set not only in two stages when the level is high and when it is low, but also in multiple stages .

  Further, as an additional condition for the specific image information, the specific image information may be added uniquely for each condition setting item without setting the level for the condition setting item.

  Further, the image processing apparatus may permit switching of valid / invalid processing of adding specific image information when a specific operator such as an administrator is recognized by the authentication code. That is, an operator having administrator authority may arbitrarily turn on / off the additional function of specific image information according to the additional conditions as described above.

FIG. 8 is a flowchart for explaining an example of image data storage processing in the confidential print and hold print function, and FIG. 9 is a diagram for explaining an example of image data output processing in the confidential print and hold print function. It is.
In FIG. 8, when image data for confidential printing or hold printing is input (transferred) to the image processing apparatus according to the present invention functioning as a printer (step S11), the image processing apparatus receives the image data. Then (step S12), the image data is stored in a predetermined storage means such as an HDD (step S13).

  In FIG. 9, when printing the stored image data, first, a list of hold data (image data stored in the image processing apparatus) is displayed (step S21). The list of hold data may be displayed according to a user operation, and when image data for printing is stored in the image processing apparatus, the list may be displayed at all times.

  Then, output data for image formation is specified from the list of hold data (step S22). The output data can be specified according to the user's selection operation for the list display of hold data. Next, it is determined whether or not print user authentication is necessary (step S23). A print that requires authentication of the print user is the above-mentioned confidential print, and a print that does not require authentication is the above-mentioned hold print.

  If the print does not require user authentication in step S23, the specified output data is output as it is (step S30), and the process ends. If the print requires user authentication in step S23, user information is requested (step S24). In this case, a display requesting input of user information is performed on the display means (for example, the display unit 102b in FIG. 1) of the image processing apparatus.

  The user inputs user information (user authentication code) in response to an input request for user information displayed on the image processing apparatus. Here, the image processing apparatus determines whether or not user information has been input (step S25). If user information has been input, the input user information is authenticated (step S26). Then, it is determined whether or not the authentication is OK (step S27). If the authentication is not OK, the user information is requested again (step S31), and the process returns to step S25 to wait for the user information.

  If the user authentication is OK in step S27, the specific image information is selected (step S28), the selected specific image information is added to the image data (step S29), and data output is performed (step S30).

  FIG. 10 is a flowchart for explaining a processing example when selecting specific image information prepared in the image processing apparatus, and shows a processing example of step S28 in FIG. First, the image processing apparatus obtains data related information (step S41). Here, the data related information is related information used for selecting the specific image information to be added to the image data from the specific image information held in the image processing apparatus. For example, the level determination result shown in FIG. Specific data related information is specified according to And specific image information is selected from the acquired data related information (step S42). The selected specific image information is added to the image data.
