--- Processing flow ---
Hereinafter, the actual procedure of the electronic application / delivery processing method in the present embodiment will be described with reference to the drawings. Of the various operations corresponding to the electronic application / delivery processing method described below, those related to the system 100 are realized by a program 102 that the system 100 reads into the memory 103 and executes. And this program 102 is comprised from the code | cord | chord for performing the various operation | movement demonstrated below.

  FIG. 3 is a flowchart showing an actual procedure example 1 of the electronic application / delivery processing method in the present embodiment. First, the electronic application receiving unit 110 of the system 100 receives application information for document delivery from the applicant terminal 150 via the network 140. In this case, as shown in the flow of the figure, the system 100 side starts accepting applications for document delivery by starting up a WEB server that accepts access from the applicant terminal 120 on the Internet (S111). On the other hand, the applicant terminal 120 accesses the WEB server using an application program such as a WEB browser and connects to the electronic application receiving unit 110 in the system 100 (S101).

  Upon receiving this connection, the system 100 returns, for example, an applicant ID and password input request to the applicant terminal 120 (S112). FIG. 4A shows an example of a screen including this input request as the output interface 505 of the applicant terminal 120. The applicant terminal 120 receives this input request and displays it on a display or the like as the output interface 506, and accepts the input of the applicant ID and password by the applicant. The applicant ID and password information received here is transmitted from the applicant terminal 120 to the system 100 via the network 140 (S102).

  The ID password receiving unit 117 of the system 100 receives the applicant ID and password information from the applicant terminal 120 and temporarily stores them in the working storage device 160. Further, the personal authentication unit 118 of the system 100 performs the personal authentication process by reading the applicant ID and password information from the working storage device 160 and collating them with the authentication database 125 (S113). If there is no problem with the result of the authentication processing here, a request for application information is returned to the applicant terminal 120. On the other hand, if there is a problem with the result of the authentication process here, the acceptance of the application information is rejected and the process is terminated.

  Not only the personal authentication process based on the ID and password as described above, but also a personal authentication process using a public personal authentication service may be applied. In this case, the Juki card reading unit 119 of the system 100 reads the secret key information in the public personal authentication system recorded on the IC chip of the basic resident register card presented by the applicant, and stores it in the working memory. Store in device 160. This reading process is executed by the applicant terminal 120, and it can be assumed that secret key information is acquired from the applicant terminal 120. FIG. 4B shows an example of a screen including a request to read the basic resident register card as an output interface 505 of the applicant terminal 120.

  At this time, the public personal authentication signature authentication unit 120 of the system 100 obtains public key information or public key certificate in the public personal authentication system via the input interface (eg, information published on the Internet). The personal authentication process or the signature verification process is executed using the public key information or public key certificate and the private key information stored in the working storage device 160.

  On the other hand, the applicant terminal 120 that has received the request for application information in step S113 transmits application information (see FIG. 6) such as address, name, and application contents to the system 100 for the document that is desired to be delivered (S103). . The electronic application reception unit 110 of the system 100 receives the application information and returns a notification of acceptance to the applicant terminal 120 (S114). The applicant terminal 120 receives and displays this notification and ends the processing (S104). On the other hand, the electronic application accepting unit 110 of the system 100 stores the application information in the work storage device 160 and uses it for other functional units (S115).

  FIG. 5 is a flowchart showing actual procedure examples 2 and 3 of the electronic application / delivery processing method in the present embodiment. Next, the visible manuscript preparation unit 111 of the system 100 reads application information (eg, information for applying for a copy of a resident's card) stored in the working storage device 160, and from this application information, a delivery document is obtained. Predetermined output contents output to (example: copy of resident's card) are extracted and stored in the work storage device 160 as first information (S201). As an example of this first information, as shown in Fig. 7 (a), document type information (eg: copy of resident's card), local government name, head information, date of issue, applicant's name, applicant Address, symbol information (eg, a predetermined mark printed on a document, etc.) can be assumed. If this first information is printed as it is, as shown in Fig. 7 (b), the document title such as "copy of resident's card" on the white paper medium without background, the date of issue, application The name of the applicant, the applicant's address, the name of the chief, and the design (solar mark in the figure).

  Further, the falsification detection information creation unit 112 of the system 100 creates falsification detection information (see FIG. 8A) including at least one item described in the delivery document from the application information, and stores it in the work storage device 160. Store. In the case of “copy of resident's card”, for example, the system 100 uses the data of “issue date”, “name of applicant” or “applicant's address”, which are important items in the copy of the resident card, as falsification detection information. Can be selected (FIG. 5B: S301). Then, the electronic signature providing unit 113 of the system 100 assigns, for example, a responsibility certificate (eg, an electronic certificate set to the person in charge of the name of the local public entity that issues a copy of the resident's card) to the falsification detection information. The falsification detection information with signature is created and stored in the work storage device 160 (S302).

  In addition, the falsification detection information image creation unit 114 with the electronic signature of the system 100 converts the output form of the falsification detection information with the electronic signature stored in the working storage device 160 on the delivery document, whether it is a point contrast or a point. The second information having the arrangement pattern is created and stored in the working storage device 160 (S303). This second information is, for example, a dot that is generated by applying an appropriate function used for digital watermark generation to the falsification detection information, as shown in the example of FIG. A pattern can be assumed. The example of FIG. 8B shows an example in which the file format of the dot pattern as the second information is a bitmap. Alternatively, as shown in FIG. 9A, the dot pattern may be a pattern in which dot coordinate values are aggregated on a two-dimensional coordinate system assumed on the paper surface of the delivery document. In this case, a CSV-format file storing the matrix of coordinate values can be assumed.

  When the delivery document is printed using the second information thus generated as a background image, an image as shown in FIG. 9B is obtained. In the example shown in FIG. 9B, on a paper medium with a dot pattern (second information) printed on the background, a document title such as “copy of resident's card”, issuance date, applicant name, applicant The address, the name of the chief, and the design (sun-shaped marks in the figure) are printed on top of each other.

  Subsequently, the check pattern creation unit 121 of the system 100 is a dark area that fits in an area of a size (for example, 63.5 micrometers) or more that can be recognized at the maximum image reading resolution of the copying machine on the delivery document. It is stipulated that a plurality of post-copied black spots that become dots and a post-copy white spot that becomes a dark spot that fits in an area of a size smaller than the size that can be recognized at the maximum image reading resolution on the copier on the delivery document Create third information. When this third information is printed on a paper medium, as shown in FIG. 11, at first glance, it appears that a diagonal line is printed on the background, but the characters “COPY” are formed at the black dot after copying. Since the hatched white dots are formed after copying, when this paper medium is copied by a copying machine, only the characters “COPY” are lifted and remain, and the copying is restrained. The check patterns such as the post-copy black spots and the post-copy white spots are stored in, for example, an appropriate storage device (such as the memory 103), and the check pattern creating unit 121 reads out the check patterns from the storage device and delivers the documents. It is assumed that it is used to be arranged in the background in the format (FIG. 10A: S401).

  The copy detection pattern creating unit 122 of the system 100 includes a square area having cyan toner, magenta toner, and yellow toner and having a predetermined size or less on the delivery document (eg, a square area having a side of 300 micrometers or less). CMY black area 3 and black toner area in which black toner is present and a K black area 4 that becomes a square area of a predetermined size or less (eg, a square area of 300 μm or less on a side) on the delivery document. 4th information (refer FIG. 12) which prescribes | regulates arranging multiple on a document is produced (FIG.10 (b): S501). Data of the CMY black area 3 and the K black area 4 as the copy detection pattern is stored in, for example, an appropriate storage device (memory 103 or the like), and read out from the storage device by the copy detection pattern creation unit 122. It shall be used to place it in the background in the format of the delivery document. The validity confirmation of the delivery document using this copy detection pattern will be described later.

  The electronic delivery information creation unit 115 of the system 100 reads the first information and the second information from the work storage device 160, creates electronic delivery information that defines the delivery document based on these, This is stored in the working storage device 160. For example, as shown in the procedure of FIG. 13A, the processing is performed by using the first information generated as a bitmap format file on the back of the layer in the first information generated as a pdf (registered trademark) format file. The two information is pasted (S601). Alternatively, as shown in the procedure of FIG. 13B, the first information that is a pdf (registered trademark) format file is in accordance with the second information (coordinate value data) generated as a CSV format file. The drawing instruction is added (S611).

  In creating the electronic delivery information, the electronic delivery information creation unit 115 may create the electronic delivery information by adding the third information in addition to the first information and the second information. . Alternatively, the electronic delivery information creation unit 115 may create electronic delivery information from the first information, the second information, and the fourth information. Since such check patterns and copy detection patterns are embedded in the delivery document, it is possible to expect effects such as checking the copy process itself of the delivery document itself and preventing misuse by clearly indicating that it is a copy of the delivery document.

  Further, in the system 100, the electronic delivery information creation unit 115 acquires printing device information as information on the delivery document printing device 170 from the input interface, and based on the printing function attribute included in the printing device information, It may be possible to determine whether or not the electronic delivery information can be created or the contents of the creation. For example, it is assumed that the printing apparatus information as shown in FIG. 14 is transmitted from the applicant terminal 120 to the system 100 together with the transmission of the application information. This printing apparatus information includes information of “printer name”, “printing resolution”, and “color printing / monochrome printing function presence / absence”. At this time, it is assumed that the system 100 includes a printing device information list as shown in FIG. 15 in an appropriate storage device (such as the memory 103), and the printing device information is checked against this printing device information list. The delivery document printing apparatus 170 is specified. Based on the information thus identified, the system 100 determines the output form required for each of the first information to the fourth information (e.g., color printing is essential, resolution is 720 dpi or more, etc.). Judge whether it can be realized by. If at least the first information and the second information among the first information to the fourth information cannot be output in this determination, the creation of the electronic delivery information itself is stopped. Alternatively, a change request notification (for example, “Please prepare a printer with a resolution of XX dpi to print the desired delivery document”) of the delivery document printing apparatus 170 is generated, Transmit to the applicant terminal 120.

  When the electronic delivery information is created, the applicant terminal 120 attempts to download it. FIG. 16 is a flowchart showing an actual procedure example 8 of the electronic application / delivery processing method in the present embodiment. At this time, in the system 100, it is assumed that the electronic delivery information is stored in the working storage device 160 constituted by a hard disk drive or the like, and the download is accepted (S701). When the applicant terminal 120 accesses the system 100 (S711), the system 100 returns an input request for the applicant ID and password to the applicant terminal 120 (S702). When the applicant terminal 120 returns the ID and password (S712), the ID password receiving unit 117 of the system 100 receives the ID and password, and the personal authentication 118 executes the authentication process in the same manner as described above (S703). If there is no problem in this authentication process, the applicant terminal 120 is notified of this, and the applicant terminal 120 receives this and returns a download request to the system 100 (S713).

  In response to a download request from the applicant terminal 150, the electronic issue unit 116 of the system 100 reads the electronic issue information from the work storage device 160 and causes the applicant terminal 150 to download it (S704). The applicant terminal 120 downloads the electronic delivery information (S714), and sends a print instruction to the delivery document printing apparatus 170 (S715). The delivery document printing apparatus 170 receives the electronic delivery information included in the print instruction, Print output is performed on an appropriate paper medium such as paper.

  The delivery document printed by the delivery document printing apparatus 170 is used by the applicant. When using it, it is possible to verify the validity at the organization to which the delivery documents are submitted. FIG. 17 is a flowchart showing an actual procedure example 9 of the electronic application / delivery processing method in the present embodiment. The document verification apparatus 130 in the institution uses the scanner 131 to execute an image scan on the delivery document to obtain image data of the delivery document (S801). Then, the second information reading device (eg, digital watermark reading device) is appropriately used to reproduce the falsification detection information with the electronic signature (S802). That is, the second information embedded in the delivery document is read and reproduced.

  Here, if the second information cannot be read and reproduced (S803: no), it is presumed that the delivery document is counterfeit, and the process ends (S808). On the other hand, if the second information can be read and reproduced (S803: yes), the electronic signature of the falsification detection information with an electronic signature is verified (S804), the signature is not falsified and valid, and the signer is valid. It is determined whether there is any (S805). In this determination, it is determined that the signature is falsified, the signature is invalid, or the signer is not valid (S805: no), and it is estimated that the delivery document is counterfeit in the same manner as described above, and the process ends ( S808). On the other hand, if it is determined that the signature is not falsified and is valid and the signer is valid (S805: yes), it is determined whether the falsification detection information matches the item described in the delivery document (S806). ). In this determination, if it is determined that the falsification detection information and the item described in the delivery document do not match (S806: no), it is estimated that the delivery document is counterfeit in the same manner as described above, and the process is terminated (S808). .

  An example of the screen on the document verification apparatus 130 at this time is shown in FIG. In this example, the “applicant name” is “XX Hanako” in the image data of the delivery document, but the “applicant name” is “XX Taro” in the information read as the second information. That is, the document verification apparatus 130 can determine that the applicant name has been falsified.

  On the other hand, if it is determined in step S806 that the falsification detection information matches the item described in the delivery document (S806: yes), it is estimated that the delivery document is authentic, and the process ends. (S807).

  Moreover, the following forms can also be assumed as the process of the validity confirmation in the document verification apparatus 130. FIG. 19 is a flowchart showing an actual procedure example 10 of the electronic application / delivery processing method in the present embodiment. In this case, the infrared camera device 20 provided in the document verification device 130 performs photographing on the delivery document (S901). The infrared camera device 20 reflects light at a plurality of positions on the delivery document when the delivery document is irradiated with light having at least one wavelength of infrared light (for example, a wavelength of 780 nanometers or more and less than 1000 nanometers). It is a device that measures the strength of waves. An image captured by the infrared camera device 20 is displayed on an infrared image display device 21.

  FIG. 20 is a diagram showing an example of copy detection in the present embodiment. For example, if the delivery document is embedded with the fourth information (CMY black area 3 and K black area 4), when the delivery document is copied, the copier copies both the CMY black area 3 and the K black area 4. It is recognized that the area is “black”, and the CMY black area 3 and the K black area 4 in the copy are composed only of black toner. Therefore, when this copy is taken by the infrared camera device 20, the infrared image becomes black.

  On the other hand, if a legitimate delivery document that is not a copy is photographed by the infrared camera device 20, the infrared image is white because the CMY black region 3 is not a “black” region, whereas the K black region. For black 4, the black toner absorbs infrared light, so that it is recognized as a “black” region and becomes black as it is.

  Accordingly, the document verification device 130 determines whether the infrared image captured by the infrared camera device 20 is a predetermined infrared image (S902), and whether the delivery document is an original or a copy. Can be estimated (S903, S904).

  FIG. 21 is a diagram illustrating an example of detection by a check pattern in the present embodiment. In addition, as described above, the check pattern creation unit 121 of the system 100 has an area of a size (for example, 63.5 micrometers) or more that can be recognized on the delivery document at the maximum resolution of image reading by a copying machine. A plurality of black spots after copying, which become dark spots that fall within the area, and white spots after copying, which become dark spots that fall within an area that is smaller than the size that can be recognized at the maximum image reading resolution of the copying machine, on the delivery document Create third information that stipulates that It can be assumed that the electronic delivery information creation unit 115 creates electronic delivery information using the third information, the first information, and the second information information. In this case, as described above, when the delivery document is copied, a check pattern appears, and a warning is given to the person who performs the copy.

  According to the present invention, documents that are required to be valid for document issuers, document contents, and document issue destinations, which were difficult to realize with the prior art, are installed in various stores, homes, countries, and local governments. It is possible to issue using a general-purpose printer and general paper. For example, certificates issued by the national or local government (copy of resident's card, tax payment certificate, etc.) or permission documents (such as licenses for use of land, roads, rivers, etc.), receipts issued by the national, local government, or companies General-purpose printers where documents such as certificates, valuable commercial tickets (such as gift certificates, cash vouchers, coupon tickets) and tickets (watching tickets, tickets, etc.) are installed in convenience stores, homes, national and local governments, etc. And can be issued using ordinary paper.

  This eliminates the need for the party receiving the document to go to the issuer (for example, a national or local government office, a store that handles gift certificates, etc.) and reduces the time required for delivery by mail, etc. Expected to reduce costs, labor, and time. In addition, it is expected that the document issuer can reduce the labor cost of the worker who performs the document issue procedure, the equipment cost for issuing, the postage fee when sending by mail, the cost of the envelope, and the like.

  Further, according to the present invention, it is possible to realize the detection of falsification, forgery, copying, and copying at a higher level than when a document is issued using special paper (exclusive paper) that has been conventionally employed. As a result, the submission destination of the document (issued by the electronic application / delivery process of the present invention) can verify the validity of the document at a higher level than before. The effect of increasing is also expected.

  Accordingly, it is possible to easily and reliably and efficiently issue a document that can be verified with a general-purpose printer and general paper.
