Description

The present invention relates to a management document creation method , a management document creation apparatus, and a document registration program for printing out a document such as a document based on document data.

  In recent years, the use of copiers and printers has become widespread, and images and documents (hereinafter referred to as documents) corresponding to image data and document data (hereinafter referred to as document data) created by a personal computer or the like can be transferred to the printer. In some cases, the printed document is used as a document, and the printed document is copied as a document using a copying machine.

  On the other hand, with a copying machine or the like, high-accuracy image copying is possible, but image quality deterioration gradually occurs as copying is repeated, such as by further copying a copy document created by copying an original document. Such image quality degradation is clearly a copied document, but the image, characters, etc. are unclear.

  On the other hand, a method of storing original document data and printing out the required number of documents when necessary is conceivable, whereby a high-quality document can always be obtained.

  From this point, when the original document data is printed out, the document identifier for the corresponding document data is assigned and printed together with the document data, and the document data is stored in the document storage unit based on the document identifier.

  When outputting a printed document, the document is read as an access key document, the document identifier is read from the access key document, and the document data stored in association with the document identifier is read from the document storage unit. There is a method for executing a printing process of a document based on data, and this makes it possible to obtain an arbitrary number of copies of a high-quality document at an arbitrary timing as if a manuscript is copied.

  By the way, when the document identifier formed in the access key document is encoded and recorded using a barcode or the like, a large number of key documents can be obtained by copying the access key document. Problems such as document leakage occur.

  On the other hand, as a method of restricting copying of information recorded in a document, there is a method of embedding information by digital watermark. From this, a document identifier is recorded in a key document by digital watermark and embedded by digital watermark. A proposal has been made to print out a document associated with the document identifier by extracting the document identifier (see, for example, Patent Document 1).

  As a result, it is possible to reliably prohibit printing processing using document data when using a document obtained by copying an access key document.

  Also, due to the random nature of the fiber material that forms the paper used for documents, etc., the use of the fact that the surface state of the paper changes randomly, a predetermined rectangle on the paper forming the access key document The image data detected as the feature quantity having the randomness of the area is stored as the unique information for specifying the paper in association with the document data together with the document identifier, thereby determining the authenticity of the access key document. Only when the document is genuine (true), it is conceivable to print out the document using the stored document data.

  By using such an access key document, for example, it is possible to distribute, for example, one access key document instead of a multi-page document, and print the document at an arbitrary timing based on each access key document. It can be used so that it can be output.

  However, in order to distribute an access key document for printing out instead of a printed document, it is necessary to copy the access key document. At this time, if a document identifier or the like is formed in the access key document by digital watermark, depending on the capability (function) of the copying machine, the digital watermark information cannot be copied or the copy is overlaid. The document identifier formed by the watermark may not be read.

In addition, when an access key document is specified from image data with randomness on paper, there is a problem that it is not possible to execute a printing process for a designated document only by copying the access key document.

It has an excellent effect of obtaining a management document that can accurately extract registration information.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic configuration of a document management system 10 applied to the present embodiment. The document management system 10 includes a document registration device 12 and a document output device 14 and a document storage device 16 serving as a document storage unit. In the following description, the document registration device 12 and the document output device 14 will be described separately. However, each may be formed by a document processing device having both a document registration function and a document output function. Further, the document registration device 12 may have the function of the document storage device 16 together.

  In the document management system 10, the document registration device 12, the document output device 14, and the document storage device 16 are connected to each other via a network, for example. The document registration device 12, the document output device 14, and the document storage device 16 can be connected to any configuration as long as data can be transmitted between them.

  The document registration device 12 and the document output device 14 are configured to include a predetermined information processing function in a multi-function peripheral having an image reading function, a print output function, and a copying function that combines the image output function and the print output function (multifunction Copier).

  The document registration device 12 and the document output device 14 include an image reading unit 18 formed by a scanner unit or the like, a print output unit 20 and an image processing unit 22 formed by a print engine or the like. Placed on the platen glass, copy settings are made by operating the keys on the operation panel, and the start key is operated to read the image recorded on the original, and print output that forms the read image on the recording paper (original copy) To do. Further, when document data such as a document is input from a personal printer (not shown), a print output of the document or the like is executed based on the document data.

  As the document storage device 16, for example, a file server is used, and document data of a document such as a document registered by the document registration device 12 is stored in association with preset registration information.

  Incidentally, a document registration unit 24 is provided in the document registration apparatus 12 of the document management system 10 applied to the present embodiment. The document registration unit 24 receives data based on a document read from the image reading unit 24 or document data such as a document input from a personal computer (hereinafter collectively referred to as document data). Then, a registration process for storing the document data in the document storage device 16 is performed. In addition, the document registration unit 24 reads out the document data registered in the document storage device 16 by the document output device 14 and creates a management document for enabling print output.

  FIG. 2A shows a schematic configuration of the document registration unit 24. In the document registration unit 24, a registration information generation unit 26, a tag image generation unit 28, and a management document generation unit 30 are formed. The registration information generation unit 26 assigns a document ID to be assigned as a document identifier for each document data to be registered, and generates registration information including the document ID.

  Further, the management document generation means 30 specifies document data stored in the document storage device 16 by being mounted on the document output device 14 (see FIG. 1) and scanned (image read), and the document data An image (image data) for printing out a management document (hereinafter referred to as an access key document) that enables printout of a document corresponding to the document registration apparatus 12 is generated.

  FIG. 3 shows an outline of an access key document 32 applied to the present embodiment as an example of a management document. In the access key document 32, a thumbnail 36 of an image of, for example, the first page of document data is formed on a recording paper 34 of a predetermined size (for example, A4 size), and document information 38 based on the document data is formed. An outline of a document that can be printed out using the access key document 32 can be grasped from the page of the access key document 32.

  The access key document 32 is formed with an image tag 40 in which registration information is invisiblely embedded in a predetermined image.

  In the tag image generation unit 28 of the document registration unit 24 shown in FIG. 2A, an image for forming an image tag 40 in which the registration information generated by the registration information generation unit 26 is embedded in a preset image. Generate data.

  When the tag 40 of this image is generated, the registration information is binarized, the predetermined image is used as an original image, the original image is divided vertically and horizontally by a predetermined size, and binarized for each divided block. Two types of patterns that satisfy a predetermined condition are selected according to the bit value of each bit of the registration information. Thereafter, density conversion is performed according to the pattern selected for each block.

  As a result, it is possible to form the image tag 40 in which the registration information is invisible without losing the original image by performing density conversion on the original image based on the registration information.

  The embedding of registration information is not limited to this, and any known method can be used. In addition, a digital watermark technique can be used for embedding registration information. Furthermore, in the present embodiment, the registration information is embedded invisible. However, the present invention is not limited to this, and the registration information is added visually using a coding method such as a barcode or a two-dimensional code without using the original image. It may be a thing.

  On the other hand, the paper such as the recording paper 34 is formed by interleaving the fibrous material. At this time, the entanglement of the fiber material changes at random, and it is difficult to control the entanglement. Further, the surface of the paper also randomly changes due to the entanglement of the fibrous material, and when the recording paper 34 is specified, a random pattern on the surface resulting from the entanglement of the fibrous material can be used.

  As shown in FIG. 2A, the document registration unit 24 is provided with paper information registration means 42. As shown in FIG. 3, a registration area 44 is set on the recording paper 34 in the access key document 32, and when the access key document 32 is printed out, characters and images are not formed in the registration area 44. I am doing so. In the present embodiment, as an example, a rectangular area of a predetermined size adjacent to the image tag 40 is used as the registration area 44. However, the position and size of the registration area 44 may be arbitrarily set as long as they are a predetermined fixed position. Position and size can be applied.

  When the paper information registration unit 42 scans the recording paper 34 (access key document 32) loaded in the image reading unit 18 and reads the pattern on the paper surface of the registration area 44, the paper information registration means 42 stores the pattern data on the recording paper. 34 as unique information.

  The document registration unit 24 is provided with a tag information extraction unit 46. The document registration unit 24 reads the image of the image tag 40 when reading the pattern on the paper surface of the registration area 44 of the recording paper 34 used for the access key document 32, and the tag information extraction unit 46. Then, registration information embedded in the image of the image tag 40 is extracted. This registration information extraction method is performed based on a registration information embedding method.

  In the document registration unit 24, when the registration information includes the unique information of the recording paper 34 on which the access key document 32 is formed, the recording paper ID used as the recording paper identifier is given together with the document ID as the registration information, and the recording paper ID The information indicating that is added is added.

  That is, the registration information generating unit 26 of the document registration unit 24 generates registration information by (document ID of a predetermined number of digits) + (1 bit flag) + (recording paper ID). In this embodiment, as an example, a recording paper ID is generated with two digits, and when no recording paper ID is added, a 1-bit flag is set to “0”. The flag is set to “1”.

  Thereby, in the document management system 10, the document data can be stored in the document storage device 16 in association with the document ID, the recording sheet ID, and the pattern data. Further, the document registration unit 24 can generate a plurality of access key documents 32 for one document data by generating a recording sheet ID for each recording sheet 34.

  In addition, the document registration unit 24 can generate the image data used for forming the image tag 40 by inputting the registration information extracted by the tag information extraction unit 46 to the tag image generation unit 28. Thus, when the access key document 32 is copied, the image tag 40 can be formed on the recording paper 34 based on the image data generated by the tag image generating means 28.

  In the document registration device 12, when the access key document 32 is created, the document data is stored in the document storage device 16 in association with the registration information. At this time, the document storage device 16 stores the document data in association with the document ID.

  As a result, a document data registration table is created as shown in FIG. 4, and each document data is managed based on the registration table. The document storage device 16 performs file conversion when storing document data.

  Further, in the document storage device 16, when pattern data which is unique information of the recording paper 34 is registered, each pattern data is stored in association with the document ID and the recording paper ID.

  As a result, as shown in FIG. 5, a pattern data registration table for the recording paper 34 is created, and the pattern data for each recording paper 34 is managed based on this registration table.

  On the other hand, as shown in FIG. 1, a registration information reading unit 48 is formed in the document output device 14 applied to the document management system 10. As shown in FIG. 2B, the registration information reading unit 48 includes a tag information extracting unit 50 and a document data reading unit 52, and a sheet information extracting unit 54 and a sheet information collating unit 56.

  When the access key document 32 is loaded in the image reading unit 18, the document output device 14 scans the image tag 40 and the registration area 44 from the access key document 32 and reads each image data.

  The tag information extraction unit 50 extracts registration information embedded in the image tag 40 from the image data of the image tag 40 in the same manner as the tag information extraction unit 46 of the document registration unit 24 described above. The document data reading means 52 reads out the document data stored in the document storage device 16 (see FIG. 1) based on the document ID obtained from the registration information extracted by the tag information extraction means 50, and the read document data The printing process based on the above can be executed.

  The registration information reading unit 48 reads pattern data stored in the document storage device 16 based on the document ID and the recording paper ID when the recording information includes the recording paper ID.

  The paper information extraction unit 54 extracts pattern data that is unique information of the recording paper 34 from the image data read from the registration area 44 of the recording paper 34 used as the access key document 32.

  When the pattern data is read from the document storage device 16 based on the document ID and the recording paper ID, the paper information collating unit 56 collates the read pattern data with the pattern data extracted by the paper information extracting unit 54. Then, it is determined whether the recording paper 34 used for the access key document 32 is registered.

  When the pattern data on the recording paper 34 matches the registered pattern data, the registration information reading unit 48 executes document data print processing based on the document ID recorded as registration information in the access key document 32. Like to do.

  In the document management system 10 configured as described above, a document or the like is used as a document, and the document is generated by scanning and reading the document with the image reading unit 18 of the document registration apparatus 12 or a personal computer or the like. By registering the document data input to the document registration device 12 and storing it in the document storage device 16, it can be printed out from any of the document output devices 14 at an arbitrary timing.

  The document registration device 12 prints out the access key document 32 when registering the document data. When printing out the document data specified by the access key document 32, the access key document 32 is stored in the document. It is loaded into the image reading unit 18 of the output device 14 and, for example, a start key is operated so as to scan a document.

  Thereby, the document output device 14 reads out the document data specified from the information formed in the access key document 32 from the document storage device 16 and prints it out.

  By the way, the document registration apparatus 12 can output a plurality of access key documents 32 and create a plurality of access key documents 32 from one access key document 32.

  When a document having a large number of pages must be distributed to a large number of locations, only the necessary number of access key documents 32 are created and distributed.

  Here, a registration process using the document registration apparatus 12 in the document management system 10 and a printing process in the document output apparatus 14 will be described.

  FIG. 6 shows an outline of a document registration process executed by the document registration apparatus 12. In this flowchart, document data to be registered is read by a key operation on an operation panel (not shown), and the number of access key documents 32 to be printed out and whether or not to register the recording paper 34 forming the access key document 32 are determined. It is executed by setting etc.

  Such an operation can be applied with any input method such as displaying a predetermined UI on the display of the operation panel. The document data may be input by reading a document or the like with the image reading unit 18 or input from a personal computer.

  In this flowchart, in the first step 100, it is confirmed whether or not the recording paper 34 for creating the access key document 32 is to be registered. A negative determination is made and the routine proceeds to step 102. In step 102, a document ID for the document data to be registered is set, and registration information in a predetermined format including the document ID is generated.

  When registering the recording paper 34, an affirmative determination is made at step 100 and the routine proceeds to step 104. In this step 104, a document ID is set and a recording sheet ID is set according to the number of access key documents 32 to be created. Registration information for each access key document 32 is set based on the set document ID and recording sheet ID. Is generated.

  When the registration information is generated in this manner, in step 106, image data for forming a tag image in which the registration information is embedded in a preset image is generated based on the registration information. That is, image data in which registration information is embedded is generated. At this time, when registration information is set for each access key document 32, image data is generated for each registration information.

  In step 108, an access key image (image data) is generated for printing the access key document 32. At this time, for example, the access key image is generated so that the thumbnail 36 of the first page of the document data and the document information 38 such as the total number of pages and the paper size are formed.

  In the next step 110, the access key document 32 is printed out based on the generated access key image. At this time, the access key documents 32 corresponding to the set number of output sheets are printed out.

  As a result, the image tag 40 in which the thumbnail 36, the document information 38 and the registration information are embedded is formed, and an access key document provided with the registration area 44 is obtained.

  Thereafter, in step 112, it is confirmed whether or not registration of the recording paper 34 is set. When registering the recording paper 34 used to form the access key document 32, an affirmative determination is made at step 112 and the routine proceeds to step 114.

  When registering the recording paper 34, the printed access key document 32 is loaded into the image reading unit 18 to register the pattern data of the recording paper 34. First, in step 114, the access key document 32 is an image. It is checked whether or not the reading unit 18 is loaded. At this time, the access key document 32 is loaded into the image reading unit 18 and, for example, a start key (not shown) on the operation panel is operated, so that an affirmative determination is made in step 114 and the process proceeds to step 116. Is scanned together with the image tag 40 to read the registration area 44.

  In the next step 118, registration information is extracted from the image data corresponding to the image tag 40. At the same time, in step 120, pattern data of the registration area 44 as a registration pattern is extracted.

  Thereafter, in step 122, the pattern data is associated with the document ID and recording paper ID, which are registration information extracted from the image tag 40. In step 124, it is confirmed whether or not the processing for the set number of sheets has been completed.

  When the processing for the predetermined number of access key documents 32 is completed in this way, in step 126, the document data is associated with the registration information and stored in the document storage device 16. Accordingly, the document storage device 16 updates the document data registration table.

  When the recording paper 34 is registered, the pattern data of the recording paper 34 is associated with each registration information and recorded in the document recording device 16. As a result, in the document storage device 16, the registration table of the recording paper 34 is updated.

  FIG. 7 shows an outline of a document printout process using the access key document 32. When the access key document 32 is used and printing processing is performed based on the document data specified by the access key document 32, the access key document 32 is loaded into the image reading unit 18 of the document output device 14, and the number of output copies is set. For example, by operating a start key.

  In the flowchart shown in FIG. 7, in the first step 130, it is confirmed whether or not the access key document 32 has been loaded and the start switch has been operated, and an affirmative determination is made by operating the start key, and the routine proceeds to step 132. .

  In this step 132, the image tag 40 formed in the access key document 32 is read by scanning the access key document 32. At this time, in order to save the number of scans, reading of the registration area 44 of the access key document 32 (reading of the paper surface) is also performed.

  In the next step 134, registration information embedded in the image tag 40 is extracted from the image data of the image tag 40 read from the access key document 32. In step 136, it is confirmed from the extracted registration information whether the recording paper 34 is registered, that is, whether the registration information includes information indicating that the recording paper 34 is registered. To do.

  Here, when the recording paper 34 is registered for each access key document 32 and information indicating that the recording paper ID is included in the registration information, an affirmative determination is made at step 136 and the routine proceeds to step 138. .

  In this step 138, the image data of the registration area 44 obtained by scanning the registration area 44 of the access key document 32 is acquired as pattern data.

  At the same time, in step 140, the pattern data stored in the document storage device 16 in association with the document ID and the recording paper ID is acquired from the document ID and the recording paper ID included in the registration information. In step 142, the recording is performed. The pattern data read from the paper 34 and the pattern data (registered pattern data) stored in the document storage device 16 are collated.

  If the pattern data do not match, a negative determination is made in step 144 and the process proceeds to step 146 to display that the pattern data does not match on a display (not shown) and print processing using the access key document 32 Cancel.

  On the other hand, when the pattern data matches, an affirmative determination is made in step 144 and the process proceeds to step 148 to read the document data recorded in the document recording device 16 in association with the document ID of the registration information, A printing process based on the read document data is executed (step 150). If the recording paper 34 is not registered, a negative determination is made at step 136 and the process proceeds to step 146 to execute a printing process of document data based on the document ID.

  In this way, by executing the print processing of the document data using the access key document 32, only the access key document 32 is distributed and specified by the access key document 32 at an arbitrary timing at each distribution destination. Print processing can be performed on the document data to be processed.

  Also, by registering the recording paper 34 used to form the access key document 32, when the access key document 32 is a document that has only been copied by a normal copying process, the document data is printed out. It can be surely prevented from being taken out.

  On the other hand, the document management system 10 can reprint the access key document 32 by using the access key document 32 that has already been printed out.

  FIG. 8 shows an outline of the reprint process for the access key document 32. When the access key document 32 is reprinted by the document management system 10, the access key document 32 as the original is loaded in the image reading unit 18 of the document registration device 12, the number of reprints is set, and the start key is operated. It is executed by doing.

  In the flowchart shown in FIG. 8, the access key document 32 is loaded in the first step 160, and it is confirmed whether or not the number of extra prints is set and the start switch is operated. Then, the access key document 32 is scanned. As a result, the registration area 44 on the access key document 32 (recording paper 34) is read together with the image tag 40 formed on the access key document 32.

  Thereafter, in step 164, registration information embedded in the image tag 40 is extracted from the image data of the image tag 40.

  When the registration information is extracted, in step 166, it is confirmed whether or not the recording paper 34 is registered. That is, it is confirmed whether or not the recording paper ID is added to the registration information.

  Here, when the recording paper 34 is registered, an affirmative determination is made at step 166 and the routine proceeds to step 168. In this step 168, the pattern data of the recording paper 34 is acquired from the image data in the registration area 44. In step 170, the pattern data stored in the document storage device 16 is acquired based on the document ID and recording paper ID of the registration information, and in step 172, the pattern data is collated.

  In step 174, it is determined whether or not the pattern data match, that is, whether or not the access key document 32 is registered. If the pattern data does not match, a negative determination is made in step 174. The printing process for the access key document 32 is stopped.

  On the other hand, when the pattern data matches, an affirmative determination is made at step 174 and the routine proceeds to step 176. In step 176, the recording paper ID is additionally set in accordance with the number of copies to be reprinted. This additional setting of the recording paper ID can be performed by checking the recording paper ID for each document data from the pattern data management table of the document storage device 16, and using a recording paper ID for which no pattern data is registered, By adding the paper ID, a necessary number of recording paper IDs are set.

  In step 176, the recording sheet ID is set, and registration information for each set recording sheet ID is generated.

  Thereafter, in step 178, the first page of the document data specified by the document ID used to create the access key document 32, the attribute information of the document, and the like are read. First, in step 180, registration information is registered in a predetermined image. In step 182, an access key image including the thumbnail 36 and document information 38 is generated in the tag image, and the access key document 32 is generated based on the generated image data. Printing is output (step 184).

  At this time, when registering the recording paper 34, the access key document 32 in which the image tag 40 is formed for each recording paper ID is printed out.

  In this way, when the required number (set number) of access key documents 32 are printed out, it is checked in step 186 whether or not registration of the recording paper 34 is set. At this time, if registration of the recording paper 34 is not set, the reprinting process is terminated in step 186. As a result, the access key document 32 that can perform document data print processing using the document ID embedded as registration information in the image tag 40 is obtained.

  If registration of the recording paper 34 is set, an affirmative determination is made at step 186 and the routine proceeds to step 188. In step 188, if the access key document 32 for registering the recording paper 34 is loaded in the image reading unit 18 and the start key is operated, an affirmative determination is made, and the routine proceeds to step 190.

  In step 190, the access key document 32 is scanned to read the image tag 40 and the registration area 44. In step 192, registration information is extracted from the image data of the image tag 40, and a document ID and a recording paper ID are obtained. .

  At the same time, in step 194, when the pattern data of the recording paper 34 is acquired from the image data in the registration area 44, the pattern data is associated with the registration information.

  In this way, when the pattern data of the recording paper 34 is acquired for each of the access key documents 32 to be reprinted and associated with the document ID and the recording paper ID, an affirmative determination is made at step 198 and the processing proceeds to step 200. .

  In this step 200, the pattern data of the recording paper 34 is registered in the document storage device 16 in association with the document ID and the recording paper ID.

  By performing the reprint process of the access key document 32 in this manner, the image tag 40 in which registration information for specifying the document data is embedded can be formed. That is, the image tag 40 can be reproduced by copying. However, if the copied access key document 32 is further copied, it is difficult to accurately extract registration information from the image tag 40.

  On the other hand, the document registration apparatus 12 newly prints out the access key document 32 based on the registration information, so that it is possible to create the access key document 32 that enables accurate extraction of the registration information.

  Also, when the recording paper 34 forming the access key document 32 is registered, it is possible to print out the document data using only the registered access key document 32. Makes it difficult to reprint.

  At this time, since the access key document 32 in which the recording paper 34 is newly registered is created based on the registration information of the access key document 32, the access key document 32 capable of accurately printing out document data can be obtained.

  Since the document registration device 12 and the document output device 14 can be applied with a configuration to which a predetermined function obtained by adding a program to the copying machine is added, the document data can be copied as if the access key document 32 is copied. It is possible to reprint the access key document 32 that enables accurate printout.

  The present embodiment described above shows an example of the present invention and does not limit the configuration of the present invention. For example, the layout of the access key document 32 is not limited to the configuration of the present embodiment, and any configuration in which at least registration information is recorded and the recording paper 34 is registered as necessary can be applied.

  Also, the method of embedding registration information and the method for specifying the recording paper 34 are not limited to the present embodiment, and any registration method and method for specifying can be applied.
