Description

  The present invention relates to a printing system for printing securities such as gift certificates and regional promotion tickets that are strictly prohibited from being counterfeited or altered by copying or the like.

  Gift certificates that are widely used today are securities issued by specific retail stores, retail cooperatives (shopping districts, etc.), gift certificate issuing companies, etc. for the purpose of promoting sales at their own stores or member stores. one of. Regional promotion tickets with premiums that can only be used at local stores by local governments are also securities, and these securities are stipulated in the Act on Fund Settlement (Act No. 59 of 2009). It corresponds to “Prepaid payment method”.

  In this application, “securities” refers to not only securities such as gift certificates, gift cards and book certificates, but also securities such as bills, checks, deposit securities, local bond securities, property rights securities such as pledged securities, stock certificates, etc. Employee securities such as investment securities, beneficiary securities such as investment trusts, income stamps, gold certificates such as postage stamps, securities representing certain rights and values such as admission tickets, and individual and individual authority Including ID cards, access cards, etc. In addition, brand protection certificates, brand protection cards, product warranty cards, dealer certificates, unopened lighting seals, unopened packages, etc. used to prevent counterfeiting and counterfeiting of products are also It shall be included in “Securities”.

  With regard to such securities, an environment in which fraudulent acts such as copying, forgery and alteration are likely to occur with the spread of electronic devices such as high-performance copiers and scanners and printers with high-definition image reading functions in recent years It has become.

  Counterfeiting securities is an act that is severely punished under Article 162 of the Criminal Code, but technology that can be easily detected at retail sites where such forged securities are actually used is required. ing.

  Techniques for dealing with unauthorized duplication and counterfeiting of securities such as gift certificates include holographic foil on securities securities and embossing after printing, etc. It can be prevented from forgery.

  However, unlike securities bonds and the like, securities are short-lived because they are used up once, so there is a drawback that it is too costly to apply such special processing to the bill.

  For this reason, as a technique for identifying the authenticity of securities, there is an example of using hidden printing with fluorescent ink using a special background pattern that reacts with black light (for example, see Patent Document 1).

JP-A-9-175067

  However, in the case of securities that have undergone such special printing, it is necessary and time-consuming to check the authenticity of the securities with a black light, etc., and there is a device such as a black light for checking securities. Has to be equipped in advance in each use site such as a retail store.

  The present invention has been made in view of the above-mentioned problems, and forges even without applying special anti-counterfeiting processing such as holograms and watermarks that require cost increase to the material of securities certificate media. The purpose is a securities printing system for printing securities that are difficult to do.

  In order to solve the above-mentioned problems, a securities printing system of the present invention is a securities printing system for printing a striated pattern on a bill of securities, and each of the securities to be printed has a plurality of different numbers. Or an ID management unit that assigns ID information composed of a plurality of character columns or a combination of a plurality of characters and numbers, and all or a part of the ID information columns (hereinafter, this column) And a basic chromatic pattern graphic memory that stores in advance a basic chromatic pattern graphic corresponding to numbers or characters arranged in the target column), and the ID information given to each of the securities printed by the ID management unit The basic chromatic pattern corresponding to the character or number in the target column is read from the storage means, and the chromatic pattern is created by combining the read basic chromatic patterns. And a printer that prints both the ID and the ID information that is the basis for generating the pattern of the color pattern and the color pattern created by the color pattern creation unit. It is characterized by.

  Here, as the ID information provided by the ID management unit, information printed differently for each securities is used in plain text. For example, serial numbers assigned as serial numbers to a series of securities of the same type are optimal as ID information. In this case, the basic chromatic pattern graphic memory stores in advance basic chromatic pattern figures corresponding to the numbers in all the columns of serial numbers or a plurality of partial columns (hereinafter, this column is referred to as a target column).

  Further, not only plain text but also letters and numbers generated by encrypting it with a certain logic are also “ID information” in the present application.

  The ID information described in the securities may be a letter or a number, but the “ID information” in this application may be a barcode, QR code (registered trademark) or the like that can uniquely identify the ID information. "

  In addition, when both the above-mentioned colored pattern created by the colored pattern creating unit and the ID information that is the basis for creating the colored pattern are printed on the same securities, However, it is also possible to form a monolithic representation by configuring the form of a serial number character or numeric font with the above-mentioned chromatic pattern. Furthermore, the chromatic pattern in the form of a font of letters or numbers may be configured as a combination that can be easily identified by an incidental attribute such as in which column the letters or numbers are located.

  Then, by recognizing the chromatic pattern using the basic chromatic pattern printed on the securities, the basic chromatic pattern is extracted from the chromatic pattern, and the extracted basic chromatic pattern is the By analyzing the character or number of the target column of the ID information, the analyzed character or number of the target column and the character or number of the target column of the ID information written on the securities By discriminating the coincidence, the authenticity of the securities can be identified.

  As another embodiment for discriminating the authenticity of securities, a pattern in the scanning direction of the colored pattern printed on the securities is detected by a sensor, and the detected pattern is detected in advance in the scanning direction of an appropriate colored pattern. The authenticity of the securities can be determined by determining the suitability of the chromatic pattern by comparing the pattern in (1) with the reference pattern.

  Then, another subject performs the authenticity discrimination by sharing the above-mentioned logic for distinguishing the authenticity of the securities in a verification device that is physically different from the device that determines the color and prints on the securities. It is good also as a structure.

  According to the securities printing system according to the present invention, ID information consisting of a string of numbers or a character string or a combination of letters and numbers individually assigned to a series of securities to be printed is given, and a character or By combining basic colored patterns that are set in advance corresponding to numbers, it is possible to create and print unique colored patterns with individual securities. Therefore, even if a series of securities of the same type, the printed color prints are different, so it is possible to effectively detect fraud that duplicates the same color prints and forges a large amount of securities. A securities printing system can be provided.

  By notifying special features according to the specific serial number of the Saimon in advance to the counter of the store handling securities, forgery and alteration can be identified visually without using any special equipment. It is possible to provide securities, or to monitor the possibility of counterfeiting and alteration by paying attention only to the feature that the color pattern is the same even though the serial numbers of multiple securities are different. A security booklet may be provided.

  Further, even if it cannot be determined by image recognition, a configuration may be included in which forgery or alteration can be determined by analyzing the characteristics of the chromatic pattern through detailed visual analysis using a magnifying glass or the like.

1 is an explanatory diagram of an overall configuration of a securities printing system according to the present invention. FIG. The explanatory view which illustrates securities is shown. The specific structure of the printing control part which comprises the securities printing system which concerns on this invention is shown with a block diagram. An example of a colored pattern printed on securities or the like is shown, and a basic colored pattern corresponding to each number from 0 to 9 in the first digit of the serial number written on the securities is shown. An example of a colored pattern printed on securities or the like is shown, and a basic colored pattern corresponding to each number from 0 to 9 in the last two digits of the serial number is shown. An example of a colored pattern printed on securities or the like is shown, and a basic colored pattern corresponding to each number from 0 to 9 in the last three digits of the serial number is shown. An example of a colored pattern printed on securities or the like is shown, and a basic colored pattern corresponding to each number from 0 to 9 in the last 4 digits of the serial number is shown. Fig. 3 is an enlarged view of the scents printed on the securities in Fig. 2. 6 is a flowchart illustrating an operation for controlling printing of securities 9 by a print control unit. The explanatory view of the example which constituted the securities printing system concerning the present invention using the server is shown. The example which combined the coloring and the serial number printed on the ticket surface of securities is shown. A configuration for discriminating the authenticity of securities by detecting the pattern of chromatic patterns is shown in a block diagram. (A) is a schematic explanatory view of the pattern detection of the chromatic pattern, and (b), (c), and (d) are schematic diagrams of the detection signal of the chromatic pattern detected by three kinds of scanning lines. Show.

  FIG. 1 is a diagram showing an example of the configuration of a securities printing system 10 according to an embodiment of the present invention. The securities printing system 10 includes a digital printer 1 for printing securities, a processing device 2, and an image scanner 5.

The digital printer 1 is a print on demand (Print
A printer that realizes On Demand), and known printers using various methods such as inkjet, laser, electrophotography (toner), sublimation transfer, thermal melt transfer, or digital offset are used.

  The processing device 2 is composed of a general-purpose computer including a memory 7 and executes a predetermined program to supply the digital printer 1 with image information for printing on the securities face, and a printing control unit 3. The image scanner 5 implements each function of the analysis unit 4 that determines the authenticity of the securities based on the image information acquired from the securities. The image scanner 5 and the analysis unit 4 may be stored in a different device from the processing device 2. Moreover, in order to acquire image information from securities, an imaging device such as a camera may be used. As another example, the processing device 2 can be divided into a first processing device having the print control unit 3 and a second processing device having the analysis unit 4. In that case, the memory 7 can be referred to from either the first or second processing apparatus.

  FIG. 2 shows an example of securities 9 printed by the digital printer 1, for example, gift certificates. The securities 9 are printed with the Saimon 8 and can be used for “common to XX shopping streets”, have a value of “¥ 1,000”, and have a serial number of “010123”. Securities information such as is printed. The serial number is a serial number assigned to each securities 9 of the same type. Accordingly, in this embodiment, the serial number is ID information for each individual securities 9.

  The chromatic pattern 8 is a fine pattern in which geometric patterns such as wavy lines, arcs, and circles composed of lines or figures are combined. In the present application, the chromatic pattern includes a combination of geometric patterns regardless of a circular shape, an elliptical shape, or a linear shape. The securities 9 on which such a color pattern is printed cannot be easily created, and it is extremely difficult to forge. When the securities 9 are copied even with a high-resolution copying machine, the printed pattern 9 cannot be accurately duplicated due to crushing or wrinkling of the pattern, so that the copied securities 9 can be easily identified. In addition, transparent ink and special color inks with metallic luster such as gold and silver are additionally used for coloring, making it difficult to reproduce images reproduced by copiers and scanner cameras. It is also possible to include an element that can be determined.

  The pattern of the color crest 8 is determined based on the numerical value of the serial number of each securities 9. That is, even for the same type of securities 9 to which a series of serial numbers is assigned, the pattern of the stencil 8 is determined based on the numerical value of each column of the entire serial number or the numerical value of each column in the range of serial numbers. As a result, there is no securities 9 on which the same pattern 8 is printed. Based on the serial number, a mechanism for creating a different original pattern on each bill 9 will be clarified later.

  The format of the face of the securities 9, that is, the location of the Ayamon 8 and securities information on the face of the securities, and the specific characters and numbers indicating these securities information are determined in advance, and their graphics, letters, and locations It is input as a digital document 6 in which command data representing a location or the like is collected and sent to the print control unit 3.

  FIG. 3 is a block diagram showing the functional configuration of the print control unit 3. The print control unit 3 includes a chromatic pattern creation unit 11, an ID management unit 12 that manages the serial number of each securities 9 to be printed, A layer 13, a raster image processor RIP (Raster Image Processor) 14, and an image memory 15 are included.

  As described above, the coloring pattern creating unit 11 creates the pattern of the coloring pattern 8 based on the number of the serial number of each securities 9 to be printed. In this example, among the serial numbers of 6 digits (columns), For example, the lower four digits are set as the target digits, and 10 basic colored patterns from 0 to 9 are preset in each digit.

  4A to 4D exemplify basic chromatic patterns, FIG. 4A shows basic chromatic patterns corresponding to the numbers 0 to 9 in the first digit, and FIG. 4C shows the basic chromatic pattern corresponding to each number from 0 to 9, FIG. 4C shows the basic chromatic pattern corresponding to each number from 0 to 9 in the third digit, and FIG. A basic chromatic pattern corresponding to each number from 0 to 9 in the last 4 digits is shown. In this way, the 40 basic pattern graphics corresponding to the four digits 0 to 9 are stored in the basic pattern graphic memory 16 secured in advance in the memory 7.

  The print controller 3 starts printing of the securities 9 when a print request for starting the printing of securities is input. Then, the ID management unit 12 manages the 6-digit serial number of each securities, which is ID information, by counting and assigning serial numbers one by one each time the securities 9 are printed. The ID management unit 12 does not have a function of counting each time it is printed, but has a function of creating a large amount of serial number data based on a predetermined rule and sequentially sending it to the layer 13 Good.

  The chromatic pattern creating unit 11 extracts the basic chromatic pattern figure corresponding to the last four digits of the serial number counted by the ID management unit 12 from the basic chromatic pattern graphic memory 16 and combines the extracted basic chromatic pattern figures. To create a chromatic pattern 8. For example, in the case of the securities 9 with the serial number “010123”, the four basic colors shown in FIGS. 4A to 4D, each surrounded by a square frame, corresponding to the last four digits of the value “0123”. A crest pattern 8 shown in FIG. 5 is created by selecting a crest pattern and combining them into a single figure.

  In this way, 10,000 basic patterns can be created by setting 10 basic patterns in each of the four digits.

Basically Simon graphics memory 16 are stored a plurality of files 25 ₁ to 25n, Simon creator 11, selects one of the files from the file 25 ₁ to 25n are stored in the basic Simon graphic memory 16 Then, the basic chromatic pattern corresponding to each digit is read from this file. Forty basic pattern patterns corresponding to the four digits 0 to 9 shown in FIGS. 4A to 4D are stored in one file 25k.

  As another example, if the target digit in the serial number is set to 5 digits or more, and the basic chromatic pattern corresponding to the numbers 0 to 9 of each digit is set, even if one file is used, 1 More than 10,000 copies of the same type of securities 9 can be printed.

  The basic chromatic pattern is a complex pattern that itself combines geometrical patterns such as wavy lines, arcs, and circles. Or duplication becomes difficult. Each basic chromatic pattern is not only different in shape, but can also be distinguished by line thickness and color. Although the basic chromatic pattern figures corresponding to the numerical values from 0 to 9 in the second digit shown in FIG. 4C are shown in the same pattern, they can actually be expressed in different colors.

  The layer 13 is a security for printing the serial number managed by the ID management unit 12 every time the securities 9 are printed and the command data representing the chromatic pattern 8 created by the chromatic pattern creating unit 11 based on the serial number. 9 is sent to the raster image processor 14 in superposition with the digital document 6 on which the bill format is shown. A plurality of digital documents 6 are set in advance according to the ticket format, and the layer 13 selects the designated digital document 6 from these and superimposes the command data.

  The raster image processor 14 which is software is a printer that actually combines a combination of characters, figures and the like expressed in the digital document 6 on which the command data is overlaid with a chromatic pattern image corresponding to the serial number. Expands to a two-dimensional bitmap image for output.

  The image memory 15 temporarily stores the developed bitmap image, converts it into image data, and transfers it to the digital printer 1.

  The analysis unit 4 performs pattern recognition processing by pattern matching processing with each basic coloring pattern graphic stored in the basic coloring pattern memory 16 for the image of the coloring pattern 8 of the securities 9 read by the image scanner 5. The authenticity of the securities 9 that read the chromatic pattern 8 and the accuracy of the printed image are determined. As described above, the analysis unit 4 is not necessarily incorporated into the processing device 2, but is incorporated into another verification device and shares logic related to the composition of the color pattern, so that another subject performs the authenticity discrimination. You may comprise.

  In the securities printing system 10 having the above-described configuration, an operation for controlling printing of the securities 9 by the print control unit 3 will be described with reference to a flowchart of FIG.

The print control unit 3 receives a print request, Simon creation unit 11 selects one file from among the files 25 ₁ to file 25n basic Simon graphics stored in the basic Simon graphic memory 16 (Step S1). Here, it is assumed that the file 25k storing the basic chromatic patterns shown in FIGS. 4A to 4D is selected by the print control unit 3.

  Then, after selecting the basic chromatic pattern graphic file, the chromatic pattern creating unit 11 determines from the count value of the ID management unit 12 whether the number of securities 9 to be printed is less than 10,000 (step S2). That is, it is determined whether or not the last four digits of the count value are less than “9999”. If “YES” is less than 10,000, the ID management unit 12 adds “1” and counts the serial number (step S4). However, it is assumed that the initial value “010000” is set in the ID management unit 12 in the process of step S4 when the first securities 9 are printed.

  When the serial number is counted by the ID management unit 12, the chromatic pattern creating unit 11 determines the pattern of the chromatic pattern 8 based on the counted serial number. In this case, in the case of the first securities 9, the last 4 digits of the serial number are “0000”. Therefore, the basic color of each digit “0” from the basic pattern image file 25 k selected in step S 1. A crest pattern is extracted, and a pattern of the crest 8 is created by combining these four basic chromatic patterns (step S5).

  When the chromatic pattern creation unit 11 creates the chromatic pattern, the print control unit 3 counts the chrominance pattern and the ID management unit 12 on the digital document 6 representing the input bill format by the layer 13. The command data representing the serial number “010000” is overlapped and sent to the raster image processor 14 (step S6).

  The raster image processor 14 develops the digital document into a bitmap image (step S7). The image memory 15 temporarily stores the bitmap image, converts it into image data, and transfers it to the printer 5 (step S8). As a result, the printer 5 prints the image data.

  When the printing control unit 3 finishes printing one securities 9 in this way, it determines from the count value of the ID management unit 12 whether the number of printed securities 9 has reached the specified number (step S9). If not, the process returns to step S2. On the other hand, when the number of printed securities 9 has reached the designated number, the printing control unit 3 ends the printing of the securities 9.

  Returning to the process of step S2, if it is determined from the count value of the ID management unit 12 that the number of gift certificates printed is less than 10,000, 1 is added to the ID management unit 12 and the serial number “010001” is added. Count (step S4). At this time, since the last four digits of the serial number is “0001”, the coloring pattern creating unit 11 corresponds to “0” from the fourth digit to the second digit, and “1” to the first digit. A basic chromatic pattern is extracted from the basic chromatic pattern graphic file 25k, and a pattern of the chromatic pattern 8 is created by combining these four basic chromatic patterns (step S5). Then, the layer 13 is developed into a bitmap image by superimposing the chromatic pattern and the serial number “010001” by the ID management unit 12 on the digital document (step S6) and outputting it to the raster image processor 3. (Step S7), the image data is converted into image data in the image memory 15 (Step S8), and the securities 9 are printed.

  In this way, the print control unit 3 repeats the processing from step S2 to step S9 while the specified number of prints of the securities 9 from the client has not been reached, and the serial number counted by the ID management unit 12 is repeated. Creates a chromatic pattern by combining the basic chromatic patterns corresponding to the last four digits, outputs the serial number and the digital document with the chromatic pattern overlaid to the raster image processor 14 and develops it into a bitmap image. Further, the securities 9 are printed by being converted into image data by the image memory 15. During this time, the pattern 9 shown in FIG. 5 is printed on the securities 9 whose 123rd serial number is “010123”.

  When the designated number of prints of the securities 9 is 10,000 or more, the processing from step S2 to step S9 is repeated, and in step S4, the ID management unit 12 increments the serial number from “010000” by one. Add. When 10,000 securities 9 are printed, the serial number is “019999”, the print control unit 3 is changed from the process of step S2 to the process of step S3. A file different from the file 25k is selected from the pattern graphic memory 16.

  Then, after the file is selected, when the ID management unit 12 adds 1 in step S4, the count value of the serial number becomes “020000”. Therefore, the chromatic pattern creating unit 11 reads out the basic chromatic pattern figure corresponding to each number of the last four digits “0000” of the serial number from the newly selected file and creates a chromatic pattern. The layer 13 superimposes this chromatic pattern on the digital document and the serial number “010000” by the ID management unit 12, outputs it to the raster image processor 3, develops it into a bitmap image, and further converts it into image data by the image memory 15. Thus, the securities 9 are printed.

  Thereafter, similarly, while the specified number of prints of the securities 9 from the client has not been reached, while the ID management unit 12 counts the serial numbers from “020000” to “029999”, this newly selected The basic chromatic pattern corresponding to the last four digits of the serial number is read from the file. Then, a pattern of the chromatic pattern 8 is created by combining these figures.

  During this time, when the number of printed sheets reaches the designated number, printing of the securities 9 is completed. If the designated number of sheets has not been reached, the storage unit 25 similarly stores the next in the basic pattern graphic memory 16. While the ID management unit 12 counts the serial numbers from “030000” to “0399998”, a pattern of the last four digits of the stencil 8 is created. Are printed on the securities 9 together with the serial number.

  As described above, the mechanism for creating a color pattern according to the serial number can be created according to the number of sheets that need to be printed, or a color pattern corresponding to the required number of sheets to be printed in advance. It is also possible to adopt a method in which a crest is created and temporarily stored in a memory, and this is corresponded to the digital document 6 and sequentially sent to a layer.

  In this way, the pattern of the scent pattern 8 printed on each securities 9 is determined in relation to the serial number that is the ID information described in each. Therefore, if the reverse process of creating the printed pattern of the printed securities 9 is performed, the analyzed four-digit number is the last four digits of the serial number described in the securities 9. It will be equal to the number. Using this, the authenticity of the securities 9 can be identified.

  In order to discriminate the authenticity of the securities 9, an image of the chroma pattern of the securities 9 to be identified is read by an image scanner 5 or an imaging device such as a camera. Then, by sending the read image to the analysis unit 4, the analysis unit 4 performs a pattern recognition process with each basic color pattern graphic stored in the basic color pattern graphic memory 16. In this way, the pattern of the chromatic pattern is broken down into basic chromatic patterns. And when it cannot be decomposed | disassembled into a basic chromatic pattern figure, it can discriminate | determine that the securities to be identified are 贋 at that time.

  On the other hand, if it can be decomposed into basic chromatic patterns, the analysis unit 4 detects which number of the last four digits corresponds to each basic chromatic pattern extracted by the decomposition. Determine a 4-digit number. And when this numerical value does not correspond with the last 4 digits of the serial number described in the relevant securities to be identified, it is determined that the number is 贋.

  In this determination, the analysis unit 4 may determine the authenticity by matching the serial number described in the securities to be identified by the person by displaying the number calculated by the print control unit 3 on the display device 23, Alternatively, the identification result may be notified by recognizing the numerical value of the serial number from the image of the securities to be identified sent by the printing control unit 3 and collating it with the numerical value analyzed by the analysis unit 4. . The analysis unit 4 may read from the basic chromatic pattern graphic memory 16 every time it analyzes the basic chromatic pattern graphic, or may read it from the basic chromatic pattern graphic memory 16 in advance and store it in the internal memory. You may refer to the basic chromatic pattern.

  The authentication unit 4 for authenticity determination is stored in a device different from the processing device 2, determines authenticity from image data sent to the analysis unit via the Internet from a smartphone, a tablet terminal, etc. Alternatively, it may be returned to a tablet terminal or the like. For example, as shown in FIG. 1, at an application provider (ASP) center operated by a business operator that determines the authenticity of securities, image data of securities to be identified is transmitted from the smartphone, tablet terminal, etc. via the Internet. In response to this, a system for analysis at the ASP center is also possible.

  With regard to the ID information in the present invention, in the above embodiment, the serial number assigned to each securities 9 to be printed is ID information. However, the serial number is not limited to a numeric string of serial numbers, but is a letter such as alphabet or kana characters. Or a string of letters and numbers. For example, “Kiha 01234”. When serial numbers including such characters are used as ID information, as in the case of a numeric string, all columns or a plurality of partial columns are set as target columns, and characters or numbers written in these columns are respectively The corresponding basic chromatic pattern graphic is stored in the basic chromatic pattern graphic memory 16 in advance.

  Then, the chromatic pattern creating unit 11 extracts basic chromatic pattern figures corresponding to characters or numbers in the target column of the ID information allocated to the securities 9 printed by the ID management unit 12, and combines them to add chromatic colors. A crest 8 is created. In this case as well, by performing pattern recognition processing with each basic color pattern graphic stored in the basic color pattern graphic memory 16, the character or number of the target digit is recognized, and the ID written in the securities 9 is recognized. The authenticity can be identified by comparing the information.

  Further, the ID information corresponding to each chromatic pattern may be encrypted information. For example, if the serial number “010123” is encrypted using a predetermined encryption key, the encrypted characters or numbers or the characters and numbers also become the ID information. By doing so, it becomes more difficult to analyze the relationship between the serial number and the coloring pattern, and the certainty of forgery prevention is increased. Furthermore, not only the serial number but also the text and number information printed on the surface of the securities, the text that combines “XX shopping street common” and “¥ 1,000” in FIG. ID data may be obtained by encrypting compressed data with an encryption key.

  FIG. 7 shows a specific configuration example of the securities printing system 10 according to the embodiment of the present invention, and the processing device 2 is configured by servers 20 connected to each other via a communication line 24 such as the Internet. . The server 20 is managed by a printing company that operates the securities printing system 10. Upon receiving a print request from the client device 21, the server 20 controls the digital printer 1 and executes a printing process to perform on-demand. Printing is realized. The server 20 may be managed by a service provider having a different entity from the printer, and may control the digital printer 1 according to a request from a printer that operates the securities printing system 10.

  The server 20 stores the digital document 6 for each security requested for printing in the database 22, and reads the digital document corresponding to the designated security 9 in response to a print request from the client device 21. Then, the server 20 superimposes a different color pattern and serial number on the read digital document and develops it into a bitmap image, further converts the bitmap image into image data, and the digital printer. 1 is printed out. These series of processes are the same processes as described above.

  In addition, the server 20 reads the image of the pattern 8 of the securities 9 to be discriminated read by the image scanner 5 and stores the basic pattern and pattern stored in the basic pattern graphic memory 16 secured in the database 22. By performing the recognition process, the process for determining the authenticity of the securities as described above is also performed. In addition, the practitioner who performs the authenticity determination may be a printer that operates the securities printing system, or may be a service provider having a different entity.

  In addition, the server 20 determines the authenticity of the securities 9 from the image of the securities 9 sent from the client device 21 or the mobile terminal 23 such as a smartphone. In this case, the server 20 recognizes the numerical value of the serial number by performing pattern recognition processing on the chromatic pattern of the image of the securities 9 with the basic chromatic pattern, and the numerical value of the serial number recognized from this image matches. Whether the securities 9 are authentic or not is determined, and the determination result is returned to the client device 21 or the portable terminal 23 that has transmitted the image. Therefore, at the site where the issued securities 9 are used or used, the authenticity of the securities 9 can be detected promptly.

  And in the said embodiment, the analysis of the authenticity of the securities on which the swordprint was printed is performed by decomposing the swatches into basic stencil patterns and reversing them into serial numbers. In addition to this, it can also be performed by detecting a pattern of a scent / print pattern for authenticity determination. FIG. 9 is a block diagram showing a configuration for discriminating the authenticity of securities by detecting a pattern of chromatic patterns. In the figure, a sensor 30 detects an optical pattern from a reflected pattern or transmitted light from a chromatic pattern and outputs a detection signal. The sensor 30 includes a photoelectric conversion element such as an LED, a phototransistor, or a photodiode. It is comprised by the detection element by.

  When discriminating the authenticity of the securities 40 on which the pattern 8A having the pattern as shown in FIG. 10A is printed, the sensor 30 detects at predetermined three locations along the sub-scanning direction of the pattern 8A. The elements 30a, 30b, and 30c are arranged. Accordingly, when the securities 40 and the sensor 30 are relatively moved in the main scanning direction, the detection elements 30a, 30b, and 30c are respectively moved along the scanning lines SL1, SL2, and SL3 of the chromatic pattern 8A (b of FIG. ), (C), and (d) are output. These detection signals indicate the output pattern according to the thickness of the striated pattern on the scanning lines SL1, SL2, and SL3, the line-to-line spacing and pitch, and the line color. In this example, three detection signals are provided. Are set as a detection pattern of the chromatic pattern 8A output from the sensor 30.

  In the reference pattern storage unit 31, detection patterns by the sensors 30 of the respective colored patterns (that is, appropriate colored patterns) printed on the respective bills when securities are issued are stored in advance as reference pattern data. When the detection pattern of the chromatic pattern 8A printed on the securities 40 for which the sensor 30 determines the authenticity is output, the determination unit 32 outputs the reference pattern data stored in the reference pattern storage unit 31 and the reference pattern data. In comparison, if a match with any one of the reference pattern data is obtained, a discrimination signal indicating that the securities 40 are appropriate is output.

  The securities printing system 10 according to the present invention prints a colored pattern according to the serial number of each securities to be printed on the bill face of the securities. Therefore, because the printed pattern with different patterns is printed in accordance with the serial number which is the ID information of the securities, even if the same colored pattern can be forged, a large number of false prints with different serial numbers in the colored pattern. The securities cannot be counterfeited and can be greatly effective for counterfeiting of securities. Depending on the numerical value of the serial number, a combination of a plurality of basic stencil patterns results in a sculpture with a fine pattern. Become.

  The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above-described embodiments, and can be implemented with various modifications or changes within the technical scope thereof. . For example, the embodiment describes an example in which the serial number and the color pattern are separately printed on the bill of securities. However, as shown in FIG. May be configured and printed with the scent pattern created by the scent pattern creation unit.
