Description

[0001]
[Technological field to which the invention belongs]
The present invention relates to printing of a seal stamp for stamping various documents, and more particularly to a digital seal stamp printing apparatus for automatically stamping a document by storing image data of the seal stamp in a memory.
[0002]
[Prior art]
Today, documents such as correspondences and work instructions in companies and documents handled at government offices are created by OA devices such as word processors and personal computers. A document created by such a device is printed out by a printer device and stored, for example. In this case, some documents are checked in the order of creator, checker, and approver, and for example, some documents are stored with a seal.
[0003]
  However, the process described above is troublesome for the creator, the confirmer, and the approver to perform stamping after printing the document, and forgetting the stamp or imperfect stamping may occur. In order to eliminate problems,5There is an invention of No. 54044 per year. In order to solve the above problems, the present invention stores image information of seals such as a creator, a confirmer, and an approver in a memory, and performs seal stamping as well as issuing documents.
[0004]
[Problems to be solved by the invention]
However, in the above conventional example, it is not possible to distinguish between the output by trial printing during the printing operation and the official document, and there is no distinction between the copy document held by each person and the formal document (master document). There is also a security problem with seal data (image data).
[0005]
In order to solve the above-described problems, the present invention provides a digital seal stamp printing apparatus that can easily distinguish between a copy document and a formal document (master document) and can ensure the security of seal data.
[0006]
[Means for Solving the Problems]
  According to the first aspect of the present invention, the digital seal stamp information is provided.And completion information of master document printing using the digital seal stamp informationRememberPortabilityStorage means;In the document data creation by the host device, the portability loaded in the first reading meansFrom the storage meansDesiRead the Tal seal information,SaidAdditional means for adding to document data;Printing means for performing a printing process based on document data transmitted from the host device, and reading the digital seal stamp information from the portable storage means loaded in a second reading means in the printing process, Permission means for permitting the printing means to print the document data by collating with the added digital seal stamp information and determining whether the digital seal stamp information stored in the portable storage means is accurate. , A predetermined number of copies based on the document dataOnly as master document,The digital seal stamp information in the document data is printed in seal color, and after the predetermined number of copies have been printed, master printing control means for printing the digital seal stamp information in black, and when the master document printing is completed Writing means for writing the master document completion information into the portable storage means;This can be achieved by providing a digital seal printing apparatus characterized by having
[0007]
  Here, the storage means is configured to store digital seal stamp information, and this digital seal stamp information records an image of the seal stamp as digital information and stores its size and form. The digital seal stamp information also stores personal information of the person who owns the seal, for example as personal information.TThe code number and employee number correspond. Therefore, the digital seal stamp information includes information on the seal stamp itself and personal information of the owner of the seal stamp.
[0008]
  Further, the adding means is from the storage means.DesiTal seal stamp information is read out and added to document data. The document data is print data such as document data created by a host device such as a personal computer in accordance with an application. In addition, digital seal stamp information is added to document data using, for example, OR synthesis using an OR circuit.
[0009]
  The judging means is added by the adding means.DesiDetermines whether or not document data including tall seal information can be printed. For example, whether or not the digital seal stamp information stored in the storage means is accurate, or whether the personal information included in the digital seal stamp information is accurate. Judge whether or not.
[0010]
Further, the printing means prints the digital seal stamp information in a color different from the document data as a master document. For example, the master document is a part. The confirmation of whether or not to print the master document is, for example, the following method. That is, the presence of the digital seal stamp information, the use of a printer capable of color printing, the confirmation of the final approver, and the like.
[0011]
With this configuration, in the printout of document data to which digital seal stamp information is added, the master document is output when the above conditions are met, and the digital seal stamp information is printed in a color different from that of the document data. Therefore, it is possible to reliably distinguish the master document from copying and test printing, and the reliability of the document is increased.
[0012]
  Also portableAs a storage medium, an IC card corresponds, but a flexible disk such as an FD or a CD-ROM may be used. Further, the digital seal stamp information and personal information are stored in these storage media, and an IC card reader and various drivers are used to read information from the storage media.
[0013]
With this configuration, the storage medium can be freely carried, for example, using a computer or printer connected via a network, digital seal stamp information and personal information can be read, and document data including digital seal stamp information can be printed. It can be performed.
[0014]
  Said permissionThe means is configured to determine whether or not the printing is possible based on, for example, the reliability of the digital seal stamp information stored in the storage means.
[0015]
Here, the reliability of the digital seal stamp information means that not only the digital seal stamp information stored in the storage medium but also the accuracy of personal information is judged, and if the digital seal stamp information is accurate, the subsequent printing process is performed. be able to.
[0016]
With this configuration, it is possible to prevent the document data including the digital seal stamp information from being inadvertently printed, and to ensure security.
[0017]
  furtherThe printing unit is configured to print the document data in black and print the digital seal stamp information in red, for example.
[0018]
With this configuration, the document data in which only the digital seal information is printed in red can be confirmed as a master document, and the master document can be easily confirmed.
[0019]
In this example, the digital seal stamp information is printed in red and the document data is printed in black. However, the digital seal stamp information may be printed in a color different from the print color of the document data. For example, the document data is printed in blue. The digital seal stamp information may be printed in red, or any other color combination.
[0020]
  AlsoThe printing unit is configured to print only one copy as a master document after the approval of the last approver is completed, for example. Here, there may be a plurality of approvers or one approver, and the target document dataVs.In this configuration, after the last approver approves the document data, only one copy of the master document is permitted.
[0021]
With this configuration, there is only one copy of the master document. For example, the document data to be printed thereafter is a copy or trial print, and can be reliably distinguished from the master document.
[0022]
As an additional note, the following configuration may be used.
When the printing means creates a plurality of master documents, all the master documents are printed with digital seal stamp information in a color different from the document data as described above.
[0023]
That is, for example, if the creditor and the debtor have the same master document one by one, such as a contract, it is necessary to prepare two master documents, and even in this case, the two documents may be master documents. It can be confirmed from digital seal information of different colors. In this case, red digital seal stamp information is usually printed on black document data.
[0024]
The digital seal stamp information is encrypted.
That is, in order to know the digital seal stamp information, it is necessary to decrypt and process the encrypted digital seal stamp information. Therefore, by configuring in this way, it is possible to ensure the security of the digital seal stamp information.
[0025]
The confirmation of the last approver when there are a plurality of approvers is configured to set the approval completion flag when the last approver performs the approval process, for example, by setting an approval completion flag. To confirm the last approver.
[0026]
By comprising in this way, confirmation of the last approver can be performed reliably and a master document can be printed more reliably.
The determination process performed by the determination unit is performed by, for example, decrypting encrypted digital seal stamp information and calculating a check digit.
[0027]
With this configuration, it is possible to reliably print document data including digital seal stamp information.
[0028]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<First Embodiment>
FIG. 1 is a configuration diagram of a digital seal printing system according to the present embodiment.
[0029]
In the figure, 1 is a host device such as a personal computer, and 2 is a printer device. The host device 1 and the printer device 2 are connected via, for example, a Centronics interface, and print data such as document data is supplied from the host device 1 to the printer device 2. The host device 1 is provided with a display, a keyboard (not shown), a mouse, and the like, and is operated by a user as described later. The host device 1 is provided with an IC card reading device 3, and digital seal stamp information and personal information are read by mounting an IC card described later.
[0030]
The printer device 2 prints the print data supplied from the host device 1 and outputs it to paper (recording paper). The printer device 2 includes an interface controller (not shown) and a printer controller, and print data supplied from the host device 1 is analyzed by the interface controller, and printing processing on paper is performed by the printer controller.
[0031]
The printer device 2 also has an IC card reader 4 and can read digital seal stamp information and personal information by mounting the IC card. The IC card reading device 4 is for the printer device 2, the IC card reading device 3 is for the host device 1, and the configurations of the IC card reading devices 3 and 4 are different.
[0032]
On the other hand, the IC card 5 can read data to any of the IC card readers 3 and 4, and the IC card 5 used in this example has the following configuration. That is, it has a CPU, ROM and RAM, and a code indicating that it can be used in this system is written in the RAM portion. When the marking program or the firmware of the printer apparatus accesses the IC card 5 of this example, it is confirmed by the above code that data can be exchanged with the CPU of the IC card 5. As will be described later, this function also protects the encryption key code, digital seal data, and master print information written in the IC card 5.
[0033]
FIG. 2 is a diagram showing the format of the RAM area of the IC card 5 having the above configuration. The RAM of the IC card 5 includes an encryption key code area 5a, a personal code area 5b, and an issuance document registration table 5c. The encryption key code area 5a is key data used for encryption and decryption of seal information to be added to print data, which will be described later, and digital seal stamp information, and a code that is unified within the operating range of this system is used. With this encryption key code, for example, if it is a document issued in the department to which it belongs, a stamped copy can be printed.
[0034]
The personal code area 5b is an area for storing individual data for each IC card owner, and includes a personal code indicating the owner and digital seal stamp data. The personal code is a code that can uniquely identify an owner within the system operation range such as an employee number.
[0035]
  The digital seal data is composed of seal size, seal color, and seal vector data. The seal size information is, for example, (X/Y) is stored as coordinate data, seal color data is stored in color codes such as red and orange, and actual seal information is stored as seal vector data. As described above, the digital seal stamp data is configured by vector data so as not to depend on the resolution of the device to be used. The size and color at the time of stamping are set in advance, and are not deformed or discolored during display or printing.
[0036]
Further, the issuance document registration table 5c is composed of issuance document numbers 1, 2,..., N, and registers document numbers waiting for master printing (printing of the digital seal data in the specified color (the stored color)). It is an area to do. Each area (issued document number area) includes a valid / invalid writing area and a document number area.
[0037]
In the valid / invalid writing area, when the document issuer performs the first stamping using the stamping program of this example and the document number is written to be “valid” data, “valid” is set. The “invalid” setting is made when the document for which the approval process is completed is master-printed.
[0038]
Here, the document number is a unique number for each issuance type registered in the IC card 5, and is registered in a combination type of data and serial numbers such as date and time at the time of the stamping process. In the issued document number area, the number of document numbers issued by the owner of the IC card 5 is written.
[0039]
On the other hand, FIG. 3 shows a part of the format of data to be transmitted from the host device 1 to the printer device 2 and the format of the seal print command to be added to the print data. In general, print data is described in units of pages by a control code of the connected printer device 2. Therefore, in the format shown in the figure, data is added for each page to be stamped in addition to the first page. However, when a plurality of markings are performed on the same page, the format is added to the previously set format.
[0040]
In FIG. 3A, the seal print command has a code indicating the seal print command written at the head, and then the data length of the encrypted data. The digital seal stamp information is not printed under the condition that this seal stamp printing command is not supported, or the printer device in which the IC card reader 4 is not set or the proper IC card 5 is not mounted. In this case, for example, the printing of the digital seal stamp data is stopped by discarding the data of the designated length. Therefore, erroneous recognition of data can be prevented by this configuration.
[0041]
The encrypted data is described next to the data length information. This encrypted data is data that is encrypted using the encryption key code of the IC card 5. As shown in FIG. 3B, the data content is composed of encrypted data content 1 (stamping information), encrypted data content 2 (digital seal stamp information), and a check digit.
[0042]
The encrypted data content 1 is seal information used when printing a document arranged only on the first page of each document. Therefore, the encrypted data content 1 is not written except for the first page. Each encrypted data content 1 (stamping information) has a fixed length and is a stamping information code indicating that it is stamping information, a document number, a personal code of the issuer, a personal code of the final approver, and an approval completion flag. Consists of.
[0043]
As the document number, the same number as the number written in the issued document registration table of the IC card 5 of the issuer is described. The issuer's personal code is used to specify the master document printer who will be described later. The final approver personal code is a code written for confirming the end of the approval work, and is effective for a document having a plurality of approvers, for example. When the owner of the IC card 5 having this personal code performs the sealing work, the above-described approval completion flag is turned on.
[0044]
Encrypted data content 2 (digital seal stamp information) is an area for describing the actual data of the seal stamp data to be stamped. The digital seal stamp information is described only on the page where the printing process is performed on the print data, and includes an area describing a digital seal stamp information code indicating digital seal stamp information and actual data of the stamp stamp. FIG. 3C shows digital seal stamp information 1, 2,..., Each of which includes information on the print position, seal size, seal color, and seal vector data.
[0045]
Here, the printing position is data of the position where the seal stamp is printed, and the stamp printing position of the target page is indicated by (X / Y) coordinates. The information on the seal size, seal color, and seal vector data is the same as the data registered in the RAM area of the IC card 5 described above. That is, data of the IC card 5 to be used is written as seal information in the area.
[0046]
  In addition, FIG.a) Is used to ensure that the decrypted data is valid. For example, if the check digit obtained from the decrypted data does not match, it is determined that the IC card 5 used for decryption is not valid. That is, the IC card 5 used for the decryption and the IC card 5 used for the encryption are determined to be different cards, and are used for rejecting the seal processing or the printing of the seal data. In the above configuration, the processing operation of this embodiment will be described below.
[0047]
First, the basic operation of this example will be described using the system configuration diagram shown in FIG. First, the host device 1 creates print data using an application installed in advance ((1) shown in FIG. 4). For example, document data is created using a word processor application.
[0048]
Next, this print data (document data) is sent to a print driver and converted into print data corresponding to the printer apparatus 2 ((2) shown in FIG. 4). Thereafter, the print data is sent to the printer apparatus 2 ((3) shown in FIG. 4), the command included in the print data is analyzed by the interface controller, and printed on the paper by the printer engine (shown in FIG. 4). (4)).
[0049]
The above is the basic operation. In this example, a stamping program described below is further executed. This process is a process of adding digital seal stamp information to the above-described print data and transmitting it to the printer apparatus 2. The printer apparatus 2 performs a print process based on this information. This will be specifically described below.
[0050]
FIG. 5 is a flowchart for explaining the above-described marking program. First, the user inserts the IC card 5 into the above-described IC card reader 3 in order to add digital seal stamp information to the print data created as described above. Next, a CPU (not shown) in the host device 1 performs a confirmation process for the IC card 5 (step (hereinafter referred to as S) 1). This process refers to the IC card reader 3 and confirms whether an IC card 5 usable in the present system is inserted.
[0051]
Next, the print data (print data) to be processed is designated (S2). This designation is performed by operating the keyboard of the host device 1, for example. The print data (print data) is document data created and stored according to an application as described above.
[0052]
If print data is specified, the print data (for example, a document file) is read in response to the specification (S3). Further, the number of pages to be printed is calculated, and the stamp data temporary (mark data area) for the number of pages is secured (S4). Further, it is determined whether or not a seal printing command already exists (S5). That is, it is determined whether the read print data has already undergone a sealing process, and the state of the read print data is confirmed.
[0053]
Here, if there is no seal print command in the print data (S5 is No), processing as a document issuer is performed. That is, the personal code is read from the inserted IC card 5 (S6), the personal code of the final approval candidate is written (S7), and the issuer's personal code and final approval schedule are written in the stamp data area for the first page. The personal code of the person is written (S8). That is, the personal code is read from the RAM area of the IC card 5 shown in FIG. 2, and this information is written in the issuer personal code area shown in FIG. 3B. Enter. A code indicating the stamp information and a document number are set in the stamp data area for the first page.
[0054]
Next, the document name is set in the IC card issuing document area (S9). That is, the document number is registered in the issued document registration table 5c in the IC card 5. As this document number, the same document number as that registered in FIG. 3B is registered.
[0055]
On the other hand, in the above judgment (S5), if there is already a seal printing command (S5 is Yes), the encryption key code in the IC card 5 is called (S10), the seal data is decrypted, and the validity of the data is confirmed. Then, it is set in the stamp data area for each page (S11).
[0056]
Further, a check digit is calculated to determine whether or not they match (S12). Here, when the check digits do not match (S12 is No), the program is terminated and the addition of the marking process is not permitted. On the other hand, when the check digits match (S12 is Yes), it is determined whether all pages of the print data have been processed (S13), and further, it is determined whether the document data has already been approved (S14). .
[0057]
Here, if the processing of all the pages for the document data has not been completed (No in S13), the above-described processing is continued and the processing for all the pages is completed. If the print data has already been approved (Yes in S14), the program is terminated and the addition of the seal process is not permitted.
[0058]
That is, it is determined whether the stamping process has progressed to the final approver. If the stamping process has progressed to the final approver, no further stamping process is performed.
Whether or not the above-described approval process has been completed is confirmed by confirming whether the approval completion flag is “on” or “off”. Therefore, if the approval completion flag is “ON”, the program is terminated, the addition of the stamping process is not permitted, and if the approval completion flag is “OFF”, the process proceeds to the subsequent stamping process.
[0059]
Further, before shifting to the above-described sealing process, it is determined whether there is a change in the designated final approver (S15). If there is a change in the final approver (S15 is Yes), the changed personal code of the final approver is designated (S16).
[0060]
On the other hand, as described above, when the final approver has not been stamped or when the final approver has been changed, the following stamping process is performed. FIG. 6 is a flowchart for explaining the marking process.
[0061]
First, the digital seal data registered in the IC card 5 attached to the IC card reader 3 is called (S17). Then, a preview display of the print data (print data) is performed, and the seal position of the seal data is designated on the preview display of the print data (print data) (S18). For example, the seal position of the seal data is determined by operating a mouse or the like while viewing the display screen.
[0062]
Next, after determining the seal position of the seal data as described above, the information on the designated position is registered in the seal data area (S19). That is, the printing position and digital seal data are added to the stamp data area of the corresponding page of the print data. For example, the position information of the seal added to the print position area in FIG. 3C is registered using the (X, Y) coordinates. Also, register the size of the seal to be used. Furthermore, the color and shape of the seal used are registered as seal vector data. That is, data other than the seal position data in the seal data is read out from the RAM area of the IC card 5 and registered.
[0063]
Next, it is determined whether the digital seal stamp data position has been designated for all pages that require stamping (S20), and the digital seal stamp data location designation is repeated for all pages that require stamping (S20 is No, S18). , S19).
[0064]
Thereafter, when the designation of the stamping positions for all the pages and the input process of the seal stamp information to be used are completed (Yes in S20), the personal code is called from the inserted IC card 5 and compared with the code of the final approver ( S21, S22). That is, it is determined whether the process of stamping the digital seal data has reached the final approver by the above process.
[0065]
Here, if the person who stamped the digital seal data at this time is the final approver, the approval completion flag is set to “ON” (S23). When the approval completion flag is set to “ON” as described above, the digital seal stamp data cannot be subsequently set as will be described later, and the approval completion flag “ON” becomes a condition for master printing.
[0066]
Next, the key code is read from the IC card 5 (S24), and the stamp data area is confirmed in order from the first page (S25). For example, by this confirmation processing, if data exists, a check digit is calculated (S26), encrypted using the key code in the IC card 5, and the length of the encrypted data is checked to determine the seal printing command. The creation ends (S27). Then, the information is added to the print data (S28).
[0067]
Thereafter, it is determined whether or not the above processing for all the stamp data areas has been completed (S29), and the above processing is continued until the processing for all the stamp data areas is completed (S29 is No, S25 to S28). When the processing for all the stamp data areas is completed, the above-described stamp processing is terminated (Yes in S29).
[0068]
In this way, the data creation of the seal data area in the host device 1 is completed, and the print data to which this information is added is sent from the host device 1 to the printer device 2.
[0069]
FIG. 7 is a flowchart for explaining processing in the printer apparatus, and is a flowchart for explaining processing at the time of receiving print data. First, print data input to the printer apparatus 2 is input to the interface controller via a reception interface (not shown). The interface controller receives and analyzes the data length parameter and the data indicated by the parameter (step (hereinafter referred to as ST) 1). For example, when a seal printing command is present in the print data, the IC card reader 4 connected to the printer 2 is checked (ST2, ST3). Here, when the IC card 5 is not inserted into the IC card reader 4 (No in ST2), or when the IC card 5 usable in this system is not inserted (No in ST3), the received data is Discard and move to the next data reception process (ST4). In this case, printing a printed material with seal data added is a security problem, and no printing process is performed.
[0070]
On the other hand, if both the above determinations (ST2, ST3) are yes, it is determined that a compatible IC card 5 is mounted on the IC card reader 4, and the encryption key code of the IC card 5 is determined. Read (ST5). Then, the encrypted data is decrypted and the check digit is confirmed (ST6).
[0071]
Here, if the check digit also matches, the process proceeds to the following master document confirmation process. On the other hand, if the check digits do not match (ST7 is No), the validity cannot be confirmed, so the captured data is discarded and the seal data is not printed (ST4).
[0072]
If the check digits match (ST7 is Yes), the following master document confirmation process (process after ST8) is performed. First, it is determined whether or not the decrypted data includes a seal information code (ST8). If the seal information code is not included (ST8 is No), the master print flag is turned off (ST13). On the other hand, if the seal information code is included (ST8 is Yes), the following determination is made.
[0073]
In the next determination, it is determined whether or not color printing is possible (ST9). The master document must be a color printer in order to print seal data in a specified color. Therefore, when the printer apparatus 2 is not a color printer (ST9 is No), the master print flag is turned off as described above (ST13). On the other hand, when the printer apparatus 2 is a color printer (ST9 is Yes), the following determination is performed.
[0074]
Next, it is determined whether or not the approval completion flag is on (ST10). In the master document, the condition for printing the master document is that the approval work up to the final approver has already been completed. Accordingly, when the approval work up to the final approver is not completed, that is, when the approval completion flag is off (ST10 is No), the master print flag is turned off (ST13). Therefore, in this case, the master print flag is kept off. On the other hand, when the approval work up to the final approver has been completed (Yes in ST10), the following determination is performed.
[0075]
Next, it is determined whether the printer is the owner of the IC card (ST11). If the printer is not the owner of the IC card (S11 is No), the master print flag is turned off (ST13). On the other hand, when the printer is the owner of the IC card (ST11 is Yes), the process proceeds to the next determination.
[0076]
In the next determination, it is determined whether or not the master document is unprinted (ST12). In the printing of the master document, the first printing after completion of the approval work is a condition for printing the master document. Therefore, if it is not the first printing after completion of the approval work (No in S12), the master print flag is turned off (ST13). On the other hand, if it is the first printing after completion of the approval work (Yes in S13), the determination for confirming all the master documents is ended.
[0077]
Next, when all of the above conditions are met, the corresponding document number is invalidated from the issued document registration table in the IC card 5, and thereafter the same document is not master-printed (ST14). Then, the master printing flag is turned on to enable execution of master printing (ST15).
[0078]
Next, the process shown in FIG. 8 is performed, and when the digital seal stamp information code is included (ST16 is Yes), the digital seal stamp data is developed in the image memory dedicated to the seal stamp (ST17). Here, in printing by a color page printer, for example, toners of four colors of cyan (C) / magenta (M) / yellow (Y) / black (K) are used, and an image memory for each of these colors is required. . Accordingly, also in this example, four colors of image memory dedicated to the seal stamp are prepared, and appropriate color separation processing is performed according to the color information described in the digital seal stamp data, and drawing processing is performed. However, when the master print flag is off, after all drawing operations are finished, the contents of the cyan (C) / magenta (M) / yellow (Y) / black (K) image memory are changed to the black (K) image. OR (OR) is added to the memory, and the cyan (C) / magenta (M) / yellow (Y) image memory is cleared so that the seal data is printed, for example, only in black (ST18, ST19).
[0079]
  After setting the printing conditions as described above, print data (print data) including printing of a digital seal stamp is printed. FIG. 9 is a flowchart for explaining this printing process. First, a counter (not shown) is set to "1" (step (hereinafter referred to as STP) 1), and OR (OR) is added to the print data and the digital seal data.AndSends the addition data of the print data and digital seal data to the printer engine(STP2). This operation is performed for each color of cyan (C) / magenta (M) / yellow (Y) / black (K). Therefore, if the master print flag is on and the development is performed according to the designated color, the seal data is printed in color.Next, it is determined whether the master print flag is on and the value of the counter is “1” (STP3). If the master print flag is on and the counter value is “1” (STP3 is YES), the contents of the image memory for seal printing are integrated into the black image memory (STP4).
