Description

  The present invention relates to an information processing system, an image processing apparatus, and an image processing program.

  Currently, in order to ensure the authenticity of certificates issued by local governments, etc., they are printed on expensive dedicated sheets for preventing falsification, and much effort is required to manage the paper. For example, if the dedicated tamper-proof paper is stolen, its authenticity cannot be guaranteed, so there is no theft by matching the number of sheets set in the printing machine daily with the number printed, including erroneous printing. Checking.

Further, in recent printing technologies, there is a technology for printing a tint block having the same effect on a blank paper without using a dedicated paper for preventing falsification.
With this printing technology, check characters can be printed together with a ground pattern equivalent to that of a dedicated sheet for preventing falsification. Since such a printing technique can be generally used, the same background pattern and check characters as an authentic certificate can be attached.

  As a technology related to this, for example, Patent Document 1 relates to a printed material in which a latent image that cannot be generally identified with the naked eye is applied to an aggregate pattern of curved lines, and a method for producing the printed material, and the printed material includes banknotes, stock certificates, For the purpose of imparting anti-counterfeiting and anti-counterfeiting effects such as bonds and other securities, various certificates and important documents by a copying machine, a single line, latent image where the latent image is not applied to the set of curved lines The part with the asterisk is expressed with two or more lines, and the total line width of the two or more lines with the latent image is equal to the line width of the single line without the latent image. As described above, the boundary line on the image line of the portion where the latent image is not formed and the portion where the latent image is applied is branched from a single line where the latent image is not applied, and the contour line of the basic curve and the latent image constituting the pattern It is disclosed that a straight line that intersects at a substantially right angle with respect to a straight line that touches at the intersection of That.

  In addition, for example, in Patent Document 2, when creating a form with a background pattern that checks illegal copying, it is an object to improve the degree of freedom of design and reduce the cost. A form output device that generates a security copy-forgery that consists of the basic security copy-forgery that disappears and a hidden security copy-forgery that is clearly copied when copied by a copying machine, and prints the security copy-forgery-inhibited pattern and print data by a printing device. As a hidden security pattern, it is disclosed to print a character string indicating different information for each form, such as a serial number attached to each form, a name of a distribution destination of each form, or a printing date and time.

Hereinafter, an example of a preferred embodiment for realizing the present invention will be described with reference to the drawings.
FIG. 1 is a conceptual module configuration diagram of a configuration example in the image processing apparatus according to the present embodiment.
The module generally refers to components such as software (computer program) and hardware that can be logically separated. Therefore, the module in the present embodiment indicates not only a module in a computer program but also a module in a hardware configuration. Therefore, the present embodiment also serves as an explanation of a computer program, a system, and a method. However, for the sake of explanation, the words “store”, “store”, and equivalents thereof are used. However, when the embodiment is a computer program, these words are stored in a storage device or stored in memory. It is the control to be stored in the device. In addition, the modules correspond almost one-to-one with the functions. However, in mounting, one module may be composed of one program, or a plurality of modules may be composed of one program. A plurality of programs may be used. The plurality of modules may be executed by one computer, or one module may be executed by a plurality of computers in a distributed or parallel environment. Note that one module may include other modules. Hereinafter, “connection” is used not only for physical connection but also for logical connection (data exchange, instruction, reference relationship between data, etc.).
In addition, the system or device is configured by connecting a plurality of computers, hardware, devices, and the like by communication means such as a network (including one-to-one correspondence communication connection), etc., and one computer, hardware, device. The case where it implement | achieves by etc. is included. “Apparatus” and “system” are used as synonymous terms. “Predetermined” means that the process is determined before the target process, and not only before the process according to this embodiment starts but also after the process according to this embodiment starts. In addition, if it is before the target processing, it is used in accordance with the situation / state at that time or with the intention to be decided according to the situation / state up to that point.

The image processing apparatus according to the present embodiment is an apparatus that prints a document. As shown in FIG. 1, an instruction receiving module 110, a certificate retrieval module 120, a certificate DB 125, an image generation module 130, a check character string. A generation module 140, a background pattern generation module 145, a certificate identification number generation module 150, a QR code generation module 155, an image composition module 160, a print module 170, a correspondence registration module 180, and a correspondence storage module 185 are provided.
As the documents, for example, a copy of a family register issued at a municipal office, a resident card, and the like are applicable. Hereinafter, a certificate will be mainly exemplified and described as a document to be issued. In addition, the document printed in this apparatus is issued as it is or after being subjected to processing such as stamping.

  Note that according to the present embodiment, a plurality of types of information images are printed on the certificate. An information image refers to an image code created to represent electronic data in a human-readable or machine-readable manner. Specifically, a ground pattern including a character string image, a one-dimensional barcode, a two-dimensional code, and the like. is there. As the first human-readable image code of the present embodiment, a background pattern including a check character string image is illustrated. Recently, a QR code (Quick Response code) has been used as a two-dimensional code, and this QR code is exemplified as the second machine-readable image code of the present embodiment.

The instruction reception module 110 is connected to the certificate extraction module 120. The user's operation, which is an instruction relating to the certificate issuance, is accepted and the instruction is passed to the certificate retrieval module 120. As a specific example, an issuance instruction such as a resident's card is received from a staff of a city hall.
The certificate extraction module 120 is connected to the instruction reception module 110, the certificate DB 125, and the image generation module 130. Upon receiving a certificate issuance instruction from the instruction receiving module 110, the corresponding certificate data is extracted from the certificate DB 125. Then, the extracted certificate data is transferred to the image generation module 130.
The certificate DB 125 is a database that stores certificate data, and is accessed from the certificate extraction module 120.
The image generation module 130 is connected to the certificate extraction module 120 and the image composition module 160. Certificate data is received from the certificate retrieval module 120 and an image of the certificate is generated. The generated image is passed to the image composition module 160.

  The check character string generation module 140 is connected to the background pattern generation module 145 and the correspondence registration module 180. When printing a certificate, a check character string to be printed therein is generated as a background pattern, and the check character string is passed to the background pattern generation module 145 and the correspondence registration module 180. Here, the check character string is one or more characters and is a part of a code for specifying the certificate (a certificate printed only with the code may be specified). It is printed as part. Further, the check character string may be composed of characters within a limited range. As a character in a limited range, for example, it may be a character string composed only of alphabetic characters or numbers. This is because the mobile communication device (mobile communication device 260 shown in the example of FIG. 2) is limited to characters that can be easily input, thereby facilitating the user's operation. The code may be generated using, for example, a random number or a hash value of certificate data may be calculated. The check character string generation by the check character string generation module 140 is generated independently of the certificate identification number by the certificate identification number generation module 150. That is, the check character string to be generated is a character string that is not related to the certificate identification number, and may be anything that cannot be inferred from the certificate identification number.

The background pattern generation module 145 is connected to the check character string generation module 140 and the image composition module 160. Based on the check character string generated by the background pattern generation module 145, a background pattern image is generated, and the background pattern image is passed to the image composition module 160. A check character string image is included in the generated tint block image. The background pattern may be generated using the background art described above. The size of the copy-forgery-inhibited pattern image generally corresponds to the size of the paper on which the certificate is printed, but may be a size of a part thereof.
Further, the check character string image in the copy-forgery-inhibited pattern generated by the copy-forgery-inhibited pattern generation module 145 may include an image of a character in a limited range representing the check character string generated by the check character string generation module 140. The character in the limited range may be a character in a predetermined range, for example, a character composed only of alphabetic characters or numbers. This is because the operation of the user is facilitated by limiting to the characters that can be easily input by the portable communication device. For this purpose, the check character string generation module 140 may generate characters within the limited range.

  The certificate identification number generation module 150 is connected to the QR code generation module 155 and the correspondence registration module 180. When printing a certificate, a certificate identification number to be shown in the QR code is generated, and the certificate identification number is passed to the QR code generation module 155 and the correspondence registration module 180. Here, the certificate identification number is one or more characters and is not limited to a number, and is a part of a code for specifying the certificate (a certificate printed with only the code may be specified). The certificate is printed as a QR code. The code may be generated using, for example, a random number or a hash value of certificate data may be calculated. The certificate identification number generated by the certificate identification number generation module 150 is generated independently of the check character string generated by the check character string generation module 140. Therefore, for example, when a hash value of certificate data is employed, processing such as adding a random number to the certificate data may be performed. That is, the certificate identification number to be generated is a code that is not related to the check character string, and may be anything that cannot be inferred from the check character string.

  The QR code generation module 155 is connected to the certificate identification number generation module 150 and the image composition module 160. Based on the certificate identification number generated by the certificate identification number generation module 150, an image of a QR code having a different form from the background pattern image generated by the background pattern generation module 145 is generated. The different forms mean that the shape, pattern, color, or a combination thereof is different. For example, the background pattern generated by the background pattern generation module 145 includes a human-readable character image. The generation module 155 generates an image of a QR code that is a machine-readable information image. A conventional technique may be used to generate a QR code image. Moreover, the size of the QR code to be generated may be a size that can fit in the blank portion of the certificate (so as not to overlap with characters in the certificate). Therefore, the QR code generation module 155 measures the size of the blank part in the image of the certificate generated by the image generation module 130, and the size of the QR code is within the size of the blank part. May be determined. Further, the image synthesis module 160 may be instructed to synthesize a QR code at the position of the blank portion.

The image composition module 160 is connected to the image generation module 130, the background pattern generation module 145, the QR code generation module 155, and the printing module 170. The certificate image generated by the image generation module 130 is combined with the copy-forgery-inhibited pattern image generated by the copy-forgery-inhibited pattern generation module 145 and the QR code image generated by the QR code generation module 155, and the combined image is printed in the print module 170. To pass. As the synthesis, for example, the image from the image generation module 130 and the image from the copy-forgery-inhibited pattern generation module 145 are ORed, and then the image from the QR code generation module 155 is pasted at the designated position (overwriting). Synthesis) may be performed.
The print module 170 is connected to the image composition module 160. The image synthesized by the image synthesis module 160 is output on paper. For example, printing on paper with a printer.

The correspondence registration module 180 is connected to the check character string generation module 140, the certificate identification number generation module 150, and the correspondence storage module 185. The check character string generated by the check character string generation module 140 is associated with the certificate identification number generated by the certificate identification number generation module 150 and stored in the correspondence storage module 185.
The correspondence storage module 185 is accessed from the correspondence registration module 180 and stores the check character string and the certificate identification number in association with each other.

The printer 230 prints out the certificate 280. In addition to the contents of the certificate, the certificate 280 is printed with a ground pattern including a check character string and a QR code representing the certificate identification number.
For example, the user of the mobile communication device 260 confirms the authenticity of the obtained certificate 280 (the certificate 280 is issued by an organization that should originally be issued and is not forged). The QR code in the certificate 280 is photographed. In addition, the user inputs a check character string printed on the certificate 280 using the key of the mobile communication device 260. Then, the mobile communication device 260 transmits the certificate identification number and the check character string represented by the QR code to the certificate verification server 240 via the communication line 270. The certificate verification server 240 determines whether or not the certificate identification number corresponds to the check character string, and returns the determination result to the mobile communication device 260. The mobile communication device 260 presents the determination result on the display. If it is known that the certificate identification number corresponds to the check character string, it may be determined that the certificate 280 is printed by the printer 230 (has authenticity).
The certificate verification server 240 and the mobile communication device 260 will be described later with reference to FIGS.
