Description

The present invention relates to a colored pattern display object displaying colored patterns.

In this specification, "things with colored patterns" generally refer to securities such as gift certificates, gift cards, and book coupons, bills, checks, deposit receipts, credit certificates such as municipal bond certificates, and pawn certificates. etc., stock certificates, employee certificates such as investment securities, beneficiary certificates such as investment trusts, revenue stamps, cash vouchers such as postage stamps, securities representing certain rights and values such as admission tickets, and individuals and It refers to various media on which colorful patterns are printed, such as ID cards and access cards that identify personal authority. It also includes the transport terminal.

Saimon is a geometric pattern consisting of a combination of circles, ovals, polygons, straight lines, wavy lines, arcs, etc. Since it is created by combining the two, it could only be drawn by experienced specialists. Therefore, since it is quite difficult to reproduce the color pattern, it has been used as one of the counterfeiting prevention measures for security printed matter such as securities.

However, with the recent development of digital technology, it has become relatively easy to copy a colored pattern and reproduce a similar colored pattern while applying corrections. As a countermeasure against such counterfeiting and alteration, since the colored lines are drawn in a complicated and repeated manner, there is a known technique for embedding information in this regular arrangement. Based on the information, it is possible to take actions such as stopping the operation of digital equipment such as copiers used for counterfeiting (see, for example, Patent Document 1).

Japanese Patent No. 5652787

On the other hand, saimon is an artistic geometric pattern that gives a sense of intricacy and profoundness, so it has a good affinity when printed on a medium that has social value in itself. It is widely used for the base pattern.

In that case, an identifier such as an identification number for each medium, for example, a serial number assigned to the securities in the case of securities, or a colored pattern corresponding to the owner's ID number in the case of an ID card, is printed on the surface of the medium. , the identifier of the medium on which the colored pattern is printed can be mechanically read through the pattern of the colored pattern.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a colored pattern display material in which the printed colored pattern represents a unique identifier of the printed matter (medium).

FIG. 1 is a diagram showing an embodiment of the configuration of a colored pattern printing system 10 for printing colored patterns on a medium to provide a colored pattern display material according to the present invention. to print. The colored pattern 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
This is a printer that realizes On Demand), and well-known printers using various methods such as ink jet, laser, electrophotography (toner), sublimation transfer, thermal fusion transfer, and digital offset are used.

The processing device 2 is composed of a general-purpose computer having a memory 7, and executes a predetermined program to supply the digital printer 1 with image information for printing on the face of securities; It realizes each function of the analysis unit 4 that determines the authenticity of the security based on the image information acquired from the security by the image scanner 5 . The image scanner 5 and analysis unit 4 may be stored in another device different from the processing device 2 . In addition, an imaging device such as a camera may be used to acquire image information from securities. As another embodiment, the processing device 2 can be divided into a first processing device having the print control section 3 and a second processing device having the analysis section 4 . In that case, the memory 7 will be configured so that it can be referred to by both the first and second processing units.

FIG. 2 shows an example of a security 9, such as a gift certificate, printed by the digital printer 1. As shown in FIG. This securities 9 has a colored pattern 8 printed on it, can be used for "common use in XX shopping districts", has a value of "¥1,000", and has 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. Therefore, in this embodiment, the serial number is the identifier for each individual security 9 . The pattern of the colored pattern 8 is determined based on the numerical value of the serial number of each securities 9 . Therefore, even securities 9 of the same type to which a series of serial numbers are assigned have different patterns according to the serial numbers, and there is no securities 9 printed with the same colored pattern 8 .

The face format of the securities 9, that is, the locations on the face of the securities where the colored patterns 8 and the securities information are arranged, and the specific characters and numbers indicating these securities information are determined in advance, and the figures, characters, and arrangements thereof are determined in advance. A digital document 6 in which command data representing locations and the like are collected is input and sent to the print control unit 3 . However, on the face of each security 9, a different and unique color pattern 8 is printed on the face of each security 9, and the identifier, which is the serial number of the color pattern 8, can be read. does not need to be specified. A mechanism for creating a different and unique color pattern on the face of each security 9 based on the serial number will be clarified later.

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

As described above, the color pattern creating unit 11 creates the pattern of the color pattern 8 based on the numerical value of the serial number of each securities 9 to be printed. The lower four digits of are designated as target digits, and 10 geometric patterns from 0 to 9 are set in advance for each of these digits.

Figures 4A to 4D illustrate this geometric pattern, Figure 4A shows the geometric pattern corresponding to each number from 0 to 9 in the last digit, and Figure 4B shows the geometric pattern in the second last digit. Fig. 4C shows geometric patterns corresponding to each numerical value from 0 to 9, Fig. 4C shows geometric patterns corresponding to each numerical value from 0 to 9 in the last three digits, and Fig. 4D shows the geometric patterns corresponding to the last four digits. Geometric patterns corresponding to each number from 0 to 9 in the eye are shown. Thus, 40 geometric patterns corresponding to 4-digit numerical values from 0 to 9 are stored in the colored pattern memory 16 which is reserved in the memory 7 in advance.

Each geometric pattern will be explained. The geometric pattern shown in FIG. 4A draws a star-shaped regular decagon whose corners are drawn with arcs, but with different trajectories, although there are some overlapping parts. As a result, the same figure is drawn in a plurality of patterns regularly and substantially concentrically. As a result, a plurality of drawn lines are drawn that are regularly arranged from the reference point at the center of the figure. Each of the 10 geometric patterns in FIG. 4A has a characteristic element and is assigned a numerical identifier from 0 to 9, respectively.

Specifically, in FIG. 4A , the geometric pattern corresponding to the identifier “0” (×××0) is a star-shaped regular decagon figure drawn in seven patterns. are regularly arranged. In this case, none of the patterns are drawn with thick lines. Each of the geometric patterns corresponding to the identifiers "1" (xxx1) to "4" (xxx4) is similarly drawn in seven different star-shaped regular decagon figures. However, the 1st, 3rd, 5th, and 7th drawn lines from the reference point at the center of the figure are drawn in bold. In addition, the geometric pattern corresponding to the identifier "5" (xxx5) is a star-shaped regular decagon figure drawn in six patterns, and none of the patterns are drawn in bold lines. . Each of the geometric patterns corresponding to the identifiers "6" (xxx6) to "9" (xxx9) is similarly drawn in six different star-shaped regular decagon figures. However, the 2nd, 3rd, 4th, and 5th drawn lines from the reference point at the center of the figure are drawn in bold. In this way, each geometric pattern in FIG. 4A is assigned 10 different identifiers according to the number of patterns and which pattern's figure is to be drawn with a thick line. Therefore, each geometric pattern shown in FIG. 4A is assigned an identifier based on the number of drawn lines and the arrangement order of thick drawn lines as characteristic elements.

The geometric pattern shown in FIG. 4B is also drawn in a plurality of concentric patterns of regular decagon star shapes, each corner of which is drawn with an arc line. A decagonal figure is also drawn without overlapping, and a plurality of drawn lines are regularly arranged from the reference point at the center of the figure. In the geometric pattern corresponding to the identifier "0" (xx0x), a star-shaped regular decagon figure is drawn in seven patterns, and none of the patterns are drawn in bold lines. Each of the geometric patterns corresponding to the identifiers "1" (xx1x) to "4" (xx4x) is similarly drawn with 7 different star-shaped regular decagon figures. However, the 1st, 3rd, 5th, and 7th drawn lines from the reference point at the center of the figure are drawn in bold. In the geometric pattern corresponding to the identifier "5" (xx5x), a star-shaped regular decagon figure is drawn in eight patterns, and none of the patterns are drawn in bold lines. Each of the geometric patterns corresponding to the identifiers "6" (xx6x) to "9" (xx9x) is similarly drawn with 8 different star-shaped regular decagon figures. However, the 2nd, 4th, 6th, and 7th drawn lines from the reference point at the center of the figure are drawn in bold. Therefore, each geometric pattern in FIG. 4B is also assigned an identifier based on the number of drawn lines and the arrangement order of thick drawn lines as characteristic elements.

The geometric pattern shown in FIG. 4C is obtained by drawing star-shaped regular decagon figures, in which adjacent corners are connected in loops, with different trajectories even though there are overlapping parts. Figures are regularly drawn in a plurality of concentric patterns. In this case, each geometric pattern corresponding to the identifiers "0" (x0xx) to "4" (x4xx) has curved corners of the star-shaped regular decagon, whereas the identifier Each geometric pattern corresponding to "5" (x5xx) to "9" (x9xx) is changed into a shape in which the tip of the corner of the curved line becomes an acute angle. Furthermore, each geometric pattern whose corners of the star-shaped regular decagon correspond to curved identifiers “0” (×0××) to “4” (×4××) are arranged approximately concentrically. A star-shaped regular decagon figure is drawn in a street pattern. As described with reference to FIGS. 4A and 4B, differentiation is achieved by changing the arrangement order of the thick lines drawn from the reference point at the center of the figure. Therefore, each of the geometric patterns in FIG. 4C is assigned with 10 different identifiers by giving some of the shapes of the same type a characteristic element and by drawing any of the patterns with thick lines. ing. Therefore, each geometric pattern in FIG. 4B is assigned an identifier based on the number of drawn lines and the shape drawn by the drawn lines as characteristic elements.

The color pattern in FIG. 4D is also basically a star-shaped regular decagon figure, and like the color pattern in FIG. 4C, the tip has an acute angle. It is a figure connected in a loop. And by drawing this figure with different trajectories, even though there are some overlapping parts, the same figure is drawn regularly in multiple patterns in a substantially concentric circle, and a thick line is drawn from the reference point at the center of the figure. It is differentiated by changing the placement order of the drawn lines. Therefore, an identifier is assigned to each of the bold lines using the arrangement order of the drawn lines as a characteristic element.

In this way, characteristic elements for assigning an identifier to each geometric pattern include, for example, color and line type, in addition to the thickness and number of lines to be drawn and the shape to be drawn.

Returning to the description of FIG. 3, the print control unit 3 starts printing the securities 9 upon input of a print request to start printing the securities. The identifier management unit 12 manages the six-digit serial number of each security, which is an identifier, by counting and assigning the serial number by one each time the security 9 is printed. The identifier management unit 12 does not have the function of counting each time it is printed, but rather has the 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 colored pattern creating unit 11 extracts from the colored pattern memory 16 a geometric pattern corresponding to each numerical value of the last four digits of the serial number counted by the identifier managing unit 12, and combines the extracted geometric patterns to create a colored pattern 8. to create For example, in the case of a security 9 with a serial number of "010123", (XXX3) in FIG. 4A and (XXX2X) in FIG. , (×1××) in FIG. 4C and (0×××) in FIG. 4D are selected and combined into one to create the colored pattern 8 of the pattern shown in FIG. be.

_A plurality of files 25-1 to 25n are stored in the color pattern memory 16, and the color pattern creation section 11 selects _one file from the files 25-1 to 25n stored in the color pattern memory 16, and creates this file. Read out the color pattern corresponding to each digit number from the file. 40 patterns corresponding to four digits 0 to 9 shown in FIGS. 4A to 4D are stored in one of these files 25k.

The layer 13 stores the serial number managed by the identifier management unit 12 for each printing of the security 9 and the command data representing the colored pattern 8 created by the colored pattern creating unit 11 based on the serial number. 9 is sent to the raster image processor 14 overlaid with the digital document 6 showing the face format of No. 9. A plurality of digital documents 6 are set in advance according to the face format, and the layer 13 selects a designated digital document 6 from among these and overlays the command data.

The raster image processor 14, which is software, actually prints a combination of the characters, graphics, etc. expressed in the digital document 6 on which the command data are superimposed, and the pattern image configured corresponding to the serial number. Develop into a two-dimensional bitmap image for output.

The image memory 15 temporarily stores the expanded bitmap image, converts it into image data, and transfers it to the digital printer 1 . As a result, the digital printer 1 prints the colorful pattern on the securities 9, which are printed objects. On the other hand, if the colored pattern display object is a portable terminal, this image data is output to the portable terminal and stored.

The analysis unit 4 performs pattern recognition processing by pattern matching processing with each colored pattern stored in the colored pattern memory 16 for the image of the colored pattern 8 of the security 9 read by the image scanner 5, thereby obtaining the colored pattern 8. The authenticity of the read securities 9 and the accuracy of the printed image are discriminated. As described above, the analysis unit 4 is not necessarily incorporated in the processing device 2, but is incorporated in another verification device, and by sharing the logic related to the configuration of the colored pattern, the authentication is performed by another subject. may be configured to

In the colored pattern printing system 10 configured as described above, the operation of controlling the printing of the securities 9 by the print control unit 3 will be described with reference to the flow chart of FIG.

When the print control unit 3 receives the print request, the colored pattern creating unit 11 selects _one file from the colored pattern files 251 to 25n stored in the colored pattern memory 16 (step S1). . Here, it is assumed that the print control unit 3 has selected the file 25k storing the colored patterns shown in FIGS. 4A to 4D.

After selecting the file of the colored pattern, the colored pattern creating section 11 determines whether or not the number of securities 9 to be printed is less than 10,000 based on the count value of the identifier managing section 12 (step S2). That is, it is determined whether or not the lower four digits of the count value are less than "9999". If "YES" and the number is less than 10,000, the identifier management unit 12 adds "1" to count the serial number (step S4). However, it is assumed that the initial value "010000" is set in the identifier management unit 12 in the process of step S4 when the first sheet of securities 9 is printed.

When the identifier management unit 12 counts the serial number, the colored pattern creating unit 11 determines the pattern of the colored pattern 8 based on the counted serial number. In this case, since the last four digits of the serial number are "0000" for the first sheet of securities 9, the geometric pattern of each digit "0" is selected from the pattern file 25k selected in step S1. By extracting and combining these four geometric patterns, a pattern of colored pattern 8 is created (step S5).

When the colored pattern is created by the colored pattern creation part 11, the printing control part 3 adds this colored pattern and the record counted by the identifier management part 12 to the digital document 6 representing the input face format by the layer 13. The command data representing the 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 print control unit 3 finishes printing one sheet of securities 9, it determines from the count value of the identifier management unit 12 whether or not the number of printed securities 9 has reached the designated 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 print control unit 3 finishes printing the securities 9 . Incidentally, when the colored pattern display object is a portable terminal, the process here outputs the image data of the colored pattern to the portable terminal.

Returning to the process of step S2, when it is determined from the count value of the identifier management unit 12 that the number of printed gift certificates is less than 10,000, the identifier management unit 12 is incremented by 1 to set the serial number "010001". Count (step S4). At this time, since the lower four digits of the serial number are "0001", the colored pattern creating unit 11 assigns "0" to the fourth to second digits and "1" to the first digit. The geometric patterns are extracted from the colored pattern file 25k, and the pattern of the colored pattern 8 is created by combining these four geometric patterns (step S5). Then, the layer 13 superimposes the colored pattern 8 and the serial number "010001" by the identifier management unit 12 on the digital document (step S6), and outputs the digital document to the raster image processor 3 to develop it into a bitmap image. (Step S7), it 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 until the specified number of prints of the security 9 is reached, and the lower four digits of the serial number counted by the identifier management unit 12 A colored pattern 8 is created by combining geometric patterns corresponding to each numerical value. The securities 9 are printed by converting them into image data. During this time, the colored pattern 8 having the pattern shown in FIG. When the colored pattern display object is a portable terminal, the image data of each colored pattern is stored in a number of portable terminals corresponding to the number of prints. Alternatively, the image data is stored in one portable terminal, or the color pattern is divided into a plurality of parts and stored in the same number of portable terminals.
Alternatively, when the output of the image data of the color pattern to one portable memory is completed,
When the specified number of sheets of securities 9 to be printed is 10,000 or more, the process from step S2 to step S9 is repeated, and in step S4, the identifier management unit 12 increments the serial number from "010000" by one. keep adding up. When 10,000 sheets of securities 9 are printed, the serial number becomes "019999", the print control section 3 shifts from the process of step S2 to the process of step S3, and the colored pattern creating section 11 starts the colored pattern A file other than the file 25k is selected from the memory 16. - 特許庁

After the file is selected, the identifier management unit 12 adds 1 in step S4, and the count value of the serial number becomes "020000". Therefore, the colored pattern creating unit 11 creates the colored pattern 8 by reading out the geometric patterns corresponding to the numerical values of the last four digits "0000" of the serial number from the newly selected file. The layer 13 superimposes this color pattern on the digital document and the serial number "010000" by the identifier 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. , the securities 9 are printed.

Thereafter, similarly, while the specified number of prints of securities 9 has not been reached, and while the identifier management unit 12 is counting serial numbers from "020000" to "029999", serial numbers are printed from this newly selected file. Read out the geometric pattern corresponding to each numerical value of the last four digits of . Then, these geometric patterns are combined to create the pattern of the colored pattern 8 .

During this time, when the number of printed sheets reaches the designated number, the printing of securities 9 is completed. Another file is randomly selected, and while the identifier management unit 12 counts the serial number from "030000" to "039998", a pattern 8 of the last four digits of the serial number is created and recorded. It is printed on the securities 9 together with the number.

As for the mechanism for creating a color pattern according to the serial number, as described above, it is possible to create a color pattern according to the number of prints required. It is also possible to adopt a method of creating a crest, temporarily storing it in a memory, making it correspond to the digital document 6, and sending it to successive layers.

In this way, the pattern of the colorful pattern 8 printed on each security 9 is determined in relation to the serial number, which is the identifier described on each security. Therefore, if the reverse process of creating the pattern 8 of the printed securities 9 is executed, the analyzed 4-digit numerical value will be the lower 4 of the serial number described on the securities 9. It will be equal to the numerical value of the digit. Using this, the authenticity of the securities 9 can be discriminated.

In order to read the four-digit identifier of the serial number from the colored pattern 8 printed on the security 9, the image of the colored pattern 8 of the security 9 to be discriminated 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 pattern recognition processing with each color pattern stored in the color pattern memory 16 for the sent image of the color pattern 8, It is determined whether the colorful pattern 8 is composed of any of the four geometric patterns shown in FIGS. 4A to 4D. In this case, if there is an unrecognized geometric pattern, it is determined that the security is forged or altered.

Then, the analysis unit 4 assigns the numerical values assigned to the four geometric patterns recognized by the pattern recognition process to the corresponding digits, thereby detecting a four-digit identifier. Therefore, it is possible to detect the identifier of the security 9 from the colorful pattern 8 and to determine its authenticity.

In the authenticity determination, the analysis unit 4 displays the number calculated by the print control unit 3 on the display device 23, and compares it with the serial number described in the securities to be discriminated by a person to determine the authenticity. Alternatively, the printing control unit 3 may recognize the numerical value of the serial number from the sent image of the securities to be discriminated, and collate it with the numerical value analyzed by the analysis unit 4, thereby notifying the discrimination result. . When referring to the color pattern, the analysis unit 4 may read from the color pattern memory 16 each time analysis is performed, or may refer to the color pattern read from the color pattern memory 16 in advance and stored in the internal memory. you can

The analysis unit 4 may be stored in a device different from the processing device 2 and may detect an identifier from image data sent to the analysis unit via the Internet from a smartphone, a tablet terminal, or the like, and perform authenticity determination. The results are returned to smartphones, tablet terminals, etc.

Regarding identifiers in the present invention, in the above embodiment, serial numbers are assigned to individual securities 9 to be printed. and a sequence of numbers. For example, it is a case like "kiha01234". When a serial number containing such characters is used as an identifier, all or part of multiple columns are set as target columns in the same way as for numeric strings, and the letters or numbers written in these columns correspond respectively. The painted pattern is stored in advance in a colored pattern memory 16.例文帳に追加

Then, the colored pattern creating unit 11 extracts colored patterns corresponding to the characters or numbers in the target string of the identifier assigned to each securities 9 to be printed by the identifier managing unit 12, and combines them to create colored patterns 8. create. In this case also, by performing pattern recognition processing with each color pattern stored in the color pattern memory 16, the character or number of the target digit is recognized and compared with the identifier written on the securities 9. By doing so, the authenticity can be discriminated.

Encrypted information may be used as an identifier corresponding to each colored pattern. 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 identifier. By doing so, it becomes more difficult to analyze the relationship between the serial number and the colored pattern, and the certainty of counterfeit prevention increases. Furthermore, not only the serial number but also the information on the letters and numbers printed on the surface of the securities, and in Fig. 2, the text combining "Common in ○○ shopping district" and "¥ 1,000" are data compressed, The identifier may be obtained by encrypting the compressed data with an encryption key.

Securities 9 according to the present invention have the features of colored patterns 8 corresponding to the serial numbers of specific securities 9 in advance, because the pattern of printed colored patterns 8 represents an identifier. By notifying the window of a store or the like, forgery or alteration can be visually identified without using any special device. In this case, by providing a cautionary note of the colored pattern 8 printed on the counterfeited or altered securities 9, the counterfeit securities 9 can be quickly eliminated. In addition, even if it cannot be determined by image recognition, it is possible to analyze the features of the colored pattern through detailed visual analysis using a magnifying glass.

In the above-described embodiment, the colored pattern 8 is formed by combining four types of geometric patterns, and an identifier is assigned to the securities 9 by integrating the characteristic elements of the respective geometric patterns. That is, the four geometric patterns are hierarchized to correspond to each digit of the four-digit serial number, and the identifier of each geometric pattern is arranged along the hierarchy (here, the digit) to form the four-digit serial number. Configure. However, even if the geometric pattern is not hierarchically formed to form a colored pattern, the number of drawn lines and the thickness of the lines that are drawn regularly from the reference point in one geometric pattern Identifier by differentiating at least one characteristic element among the arrangement order of the drawn lines characterized by the color of the lines, the arrangement order of the drawn lines characterized by the color of the lines, and the shape drawn by the lines according to the colored pattern display object may be assigned.

Further, in the above embodiment, the case where the colored pattern display is the security 9 has been described, but when the colored pattern display is an ID card or the like, it is difficult to visually indicate an identifier such as an ID number for security purposes. It is preferable to avoid it. Therefore, by reading the ID number from the colored pattern 8 printed on the ID card or the like, the individual is authenticated.
