Description

  The present invention relates to security of a printed material, relates to the provision of identification information for identifying that the printed material is genuinely printed, and relates to the determination of the authenticity of the printed material using the assigned identification information.

  As a personal authentication technique, a technique using biometrics such as a fingerprint of each individual, a glow pattern, a vein pattern such as a palm or a finger, or a face pattern is known. Further, as technology for authenticating an object, there are known magnetic stripes and IC chips used for cards and the like, artifact metrics used for paper containing soft magnetic fibers, and digital watermarks applied to printed materials. .

In the technology for authenticating an object, conventionally proposed ones are a problem that requires expensive materials to add identification information to the object, and complicated to authenticate using image information read by a copying machine or an image scanner. It has been pointed out that a large amount of storage capacity is required to store image information. In order to solve this problem, security information management has been proposed in which non-magnetic toner and magnetic toner are overlapped to form an image, thereby easily forming an image that is difficult to duplicate (see Patent Document 1). ).
JP 2006-178182 A

  In the above-mentioned prior art documents, a non-magnetic toner and a magnetic toner are used, and a part of characters and barcode is printed with the non-magnetic toner and the other part is printed with the magnetic toner to form a security image. ing. Whether the printed matter is authentic or not is determined by reading the magnetic material information of the security image and collating the read data with previously stored security image data.

  When applying the security image technology described above to ensure that the printed material is authentic, the magnetic material information of the security image is obtained from the printed material on which the security image incorporating the identification information is printed in order to verify the image data. Need to read.

  As an aspect in which the printed material is distributed, for example, there is an aspect in which image data for printing the printed material is transmitted via a network or a recording medium in addition to an aspect in which the printed material itself is distributed.

  In the mode in which the printed matter itself circulates, it is necessary to read the magnetic material information of the security image printed on each printed matter for both the genuine printed matter and the printed matter to be judged on the determination side for determining the printed matter. In such an aspect, since each printed matter has identification information set individually, in addition to reading the magnetic material information of the security image of the judgment subject printed matter for all the printed matter, It is also necessary to read the magnetic material information of the security image. Therefore, when security management is performed for a large number of printed materials, it is necessary to read the magnetic material information for both the printed material to be determined and the genuine printed material, so that it takes a long time to read the magnetic material information. is there.

  In the aspect of transmitting the image data, the received image data is printed on the receiver side of the image data to form a printed matter. Since this printed matter is not a genuine printed matter printed on the sender side, there is a problem that the magnetic material information of the security image cannot be read from the genuine printed matter, and the authenticity determination cannot be performed by the collation process.

  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described conventional problems and shorten the processing time for security management of printed matter. More specifically, an object of the present invention is to make it unnecessary to read the identification information of a genuine printed matter.

  It is another object of the present invention to check the identification information of a printed material to be determined and the identification information of the genuine printed material without requiring a genuine printed material in determining the authenticity of the printed material to be determined.

  In the method category, the present invention includes a form of a method for assigning identification information to a printed matter and a form of a security management method for the printed matter. The product category includes a form of a printed matter provided with identification information, a form of a print data forming apparatus, a form of a printed matter determination apparatus, and a form of a security management system for a printed matter.

  In any form, identification information for identifying the printed matter is incorporated into the printed portion of the printed matter, and this identification information is included in one of the identification dot patterns consisting of dot patterns complementary to each other. The dot pattern is printed with magnetic ink, and the other dot pattern is printed with nonmagnetic ink.

  The authenticity determination of the printed matter using the identification information is performed by comparing waveform signals obtained by scanning the identification dot pattern. The waveform signal obtained from the genuine identification information is obtained by calculation from the identification dot pattern, and the waveform signal is obtained by scanning the printed identification information with a sensor for the printed matter to be determined.

  Since the identification information of the present invention is formed based on the identification dot pattern, a waveform signal that is a reference waveform used for comparison and collation can be obtained by calculation using the identification dot pattern, and the identification information is printed on a printed matter. Is not required. As a result, it is possible to obtain a reference waveform signal for comparison and collation without preparing a genuine printed material and scanning the identification information given to the printed material with a sensor.

  In the aspect of the method for providing identification information according to the present invention, an identification dot pattern having dot patterns complementary to each other is prepared as the identification information, and one dot pattern of the identification dot pattern is printed with magnetic ink. An ink dot pattern is used, and the other dot pattern is a non-magnetic ink dot pattern for printing with non-magnetic ink. In order to give the identification information to the printed matter, at least one identification information provision region is set in the print portion of the printed matter, and the identification dot pattern is printed on the identification information provision region using magnetic ink and nonmagnetic ink.

  Here, in the magnetic ink dot pattern, the number of dots is determined by multiplying the total number of dots included in the identification dot pattern by the dot density, and the arrangement position of each dot is determined based on random information set uniquely for the printed matter.

  The inventor of the present application relates to a false match rate (FMR: False Match Rate) for erroneously judging whether or not non-correct is true, and is related to the dot density and the threshold value (set value St). It has been found that by setting the dot density to a certain value or more in the correlation coefficient, the false acceptance rate (FMR) is sufficiently small to be regarded as “0”.

  Therefore, in the present invention, based on the relationship between the false acceptance rate (FMR) and the dot density, a dot density that is sufficiently low that the false acceptance rate (FMR) can be regarded as “0” is set. The number of dots included in the magnetic ink dot pattern of the identification dot pattern is determined based on the density. Next, the arrangement position of the determined number of dots on the magnetic ink dot pattern is determined based on the random information.

  As a result, the magnetic ink dot pattern has identification information unique to the printed matter, and can be made sufficiently small so that the false acceptance rate (FMR) can be regarded as “0”.

  The area to which the identification information is added in the printing unit can be a printing unit that prints with the same single color, or a printing unit that prints with multiple colors.

  When giving identification information to a print portion printed with a single color, an identification dot pattern is defined for that color, and when giving identification information to a print portion printed with multiple colors, An identification dot pattern can be defined for at least one color. In the case of multicolor printing, in addition to defining an identification dot pattern for one color selected from among multiple colors, an identification dot pattern may be defined for a plurality of colors selected from among the multiple colors. In this case, it is necessary to prepare magnetic ink and nonmagnetic ink for each color forming the identification dot pattern.

  In the aspect of the printed matter to which the identification information of the present invention is applied, the printed matter is a dot pattern complementary to each other, and one dot pattern is a magnetic ink dot pattern printed with magnetic ink, and the other dot pattern is non-printed. An identification dot pattern having a non-magnetic ink dot pattern printed with magnetic ink. The printed material is provided with identification information for identifying the printed material by printing the identification dot pattern with magnetic ink and non-magnetic ink in at least one identification information application region set in the printing unit.

  The number of dots included in the magnetic ink dot pattern is the number obtained by multiplying the total number of dots included in the identification information provision area set in the printing unit by the dot density. In addition, the arrangement position of dots dispersed in the magnetic ink dot pattern in the identification information addition region can be determined based on random information set uniquely for the printed matter.

  The identification information application area is a print section that prints in a single color, and the identification dot pattern is determined for that color. In addition, the identification information application area is a print section that prints in multiple colors, and at least one of these multicolors is identified. The dot pattern can be defined. In a multicolor printing unit, an identification dot pattern may be formed by a combination of a plurality of colors.

  In the process of forming a printed matter with identification information, one dot pattern is a magnetic ink dot pattern printed with magnetic ink, and the other dot pattern is a nonmagnetic ink dot pattern printed with nonmagnetic ink. An identification dot pattern having a related dot pattern is printed on at least one identification information application region set in a print part of the printed material to form a printed material with identification information.

  In the step of forming creation data, a verification calculation waveform signal obtained by calculation based on the magnetic characteristics of the magnetic ink dot pattern when the identification dot pattern is scanned in a predetermined direction and the identification dot pattern are printed as the creation data. And identification information adding area data for determining a position on the printed material.

  In the step of reading the detection waveform signal for determination, the detection position on the printed material is specified based on the identification information application region data included in the creation data, and the detection waveform signal for determination is read by performing magnetic detection at the detection position.

  In the waveform comparison step, the determination detection waveform signal read from the printed material is compared with the verification calculation waveform signal included in the created data. The waveform comparison can be performed by calculating a correlation coefficient based on the amplitude value of the waveform signal at each sample point.

  In the step of determining the authenticity of the identification information, the authenticity of the identification information is determined on the basis of the comparison result in the waveform comparison step, and in the step of determining the authenticity of the printed material in the step of determining the authenticity of the printed information. Determine.

  The step of determining the authenticity of the identification information can be performed by comparing the correlation coefficient S calculated in the waveform comparison step with a set value St set as a threshold value. The set value St used in the waveform comparison is a threshold value for determining the authenticity of the identification information using the correlation coefficient S as an index. Here, the inventor of the present application uses a false acceptance rate (FMR: False Match Rate) to erroneously determine non-correctness and a false rejection rate (FNMR: False Non-Match) to erroneously determine authenticity as non-correct. The relationship with (Rate) shows a reverse change in which one increases as the set value St changes, and the other decreases, and it has been found that there is a so-called trade-off relationship.

  Therefore, in the present invention, in the step of determining the authenticity of the identification information, a set value St in which both the false acceptance rate (FMR) and the false reject rate (FNMR) are reduced is determined, and the correlation coefficient S is larger than the set value St. If it is determined to be authentic. Note that the false rejection rate (FNMR) at this time depends on the positional deviation between the identification information printed on the printed matter to be determined and the sensor that reads the identification information.

  According to the aspect of the assigning method of the present invention and the aspect of the printed matter to which the identification information is assigned, the identification information can be magnetically given in the print portion of the printed matter. In providing the identification information, by setting the position to which the identification information is added as an identification information addition area and managing the data in the identification information addition area separately from the printed matter, security can be improved with respect to acquisition of the identification information. For example, in a printed part of printed matter, by printing using magnetic ink and non-magnetic ink on portions other than the identification information adding region for adding identification information, for those who do not have the identification information adding region data, Reading information can be made difficult.

Or reading the identification information by scanning the sensor from the printed matter to which the genuine identification information is assigned can be made unnecessary.

  Further, in the authenticity determination of the identification information, the correlation coefficient S between the verification calculation waveform signal and the detection waveform signal for determination is used as an index, and a threshold value (set value St) used for comparison with the correlation coefficient S is set as follows: By setting both the false acceptance rate (FMR) and the false rejection rate (FNMR) to be small, the rate of false judgments such as misjudgment of authenticity as incorrect or true as incorrect is reduced. Can be made.

  In addition, since the false acceptance rate (FMR) and false rejection rate (FNMR) depend on the misalignment between the identification information printed on the printed matter to be judged and the sensor that reads this identification information, The accuracy of the sensor that reads the identification information can be determined according to the rate, and it is possible to avoid using an expensive reading device with higher accuracy than necessary, and to suppress the cost required for security management.

  As described above, according to the present invention, it is possible to shorten the processing time for security management of printed matter. Further, it is possible to make it unnecessary to read the identification information of the genuine printed matter.

  Further, according to the present invention, it is possible to collate the identification information of the determination target printed matter with the identification information of the genuine printed matter without requiring a genuine printed matter in determining the authenticity of the determination target printed matter.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  Hereinafter, a method for giving identification information to a printed material according to the present invention, a printed material to which identification information is added, and a security management system for the printed material will be described.

  1 and 2 are diagrams for explaining the outline of security management based on identification information according to the present invention. In FIG. 1, in order to guarantee the authenticity of the printed matter 20, unique identification information is given to the printed matter 20. The identification information is given by defining an identification information provision area 23 in the printing unit 21 of the printed matter 20 and printing the identification dot pattern 14 in the identification information provision area 23. The identification dot pattern 14 is uniquely set for the printed material 20 and can be used as identification information for specifying the printed material 20.

  The identification dot pattern 14 includes a magnetic ink dot pattern 14a printed with magnetic ink and a non-magnetic ink dot pattern 14b printed with non-magnetic ink. The two dot patterns have a complementary relationship with each other. Yes. Therefore, when the magnetic ink that prints the magnetic ink dot pattern 14a and the nonmagnetic ink that prints the nonmagnetic ink dot pattern 14b have the same color, the identification dot pattern 14 is printed in the same color. The pattern of the identification dot pattern 14 cannot be recognized. The color for printing the identification dot pattern 14 is not limited to a single color, and may be multiple colors. In the case of multicolor printing, based on the combination of the color data and the identification dot pattern 14, the print color for printing each dot of the magnetic ink dot pattern 14a and the nonmagnetic ink dot pattern 14b is set.

  The identification dot pattern 14 is printed on the identification information adding region 23 set in the printing unit 21 in the printed matter 20. FIG. 1 shows a state in which the identification dot pattern 14 is printed at the location of the identification information adding region 23 and the identification information printing unit 24 is formed. The identification information printing unit 24 is a part of the printing unit 21, and is printed with magnetic ink and nonmagnetic ink based on the identification dot pattern 14 with magnetic ink dot pattern 14a and nonmagnetic ink dot pattern 14b. Specifically, it is observed in the same manner as the printing unit 21.

  Since the magnetic ink dot pattern 14a is printed with magnetic ink, the identification information printing unit 24 can obtain a waveform signal from this portion by magnetic scanning. This signal waveform depends on the magnetic ink dot pattern 14a of the identification dot pattern 14, and since the magnetic ink pattern 14a represents identification information, the identification information can be recognized from the waveform signal.

  In the present invention, the authenticity of the printed matter is determined using a waveform signal obtained by printing each dot pattern of the identification dot pattern 14 with magnetic ink and non-magnetic ink. In order to determine the authenticity of a printed material according to the present invention, an identification information providing region 23 is defined in the printing unit 21 of the printed material 20, and an identification dot is formed using magnetic ink and nonmagnetic ink at the location of the determined identification information providing region 23. The pattern 14 is printed to form the identification information printing unit 24.

  In order to determine the authenticity of the printed matter 20, the identification information application region 23 is scanned with a magnetic sensor to detect a detection detection signal 25 for determination.

  On the other hand, a waveform signal obtained by magnetic scanning is calculated as a verification calculation waveform signal 15 by calculation from the magnetic ink dot pattern 14 a of the identification dot pattern 14. An authentic user compares the verification calculation waveform signal 15 with the determination detection waveform signal 25 obtained by detecting the printed matter 20 with a magnetic sensor by using, for example, a correlation coefficient, thereby determining the authenticity of the identification information. judge.

  Therefore, in the authenticity determination of the printed material using the identification information of the present invention, the verification waveform obtained in advance by calculation from the detection waveform signal for determination obtained by detecting the printed material to be determined by the magnetic sensor and the identification dot pattern. This is done by comparing the calculated waveform signal. Since the verification calculation waveform signal is obtained by calculation, there is no need to prepare a print pattern obtained by printing the identification dot pattern with magnetic ink and non-magnetic ink, and the print pattern is scanned with a magnetic sensor. There is no need to detect the waveform signal.

  In FIG. 2, (a) on the left side of the alternate long and short dash line is the sender side of identification information, (b) to (d) are the sender side of printed matter or printed matter information, and (e) to (G) is the recipient of identification information. The receiver side (e) to (g) determines the authenticity of the printed matter based on the identification information sent from the sender side (a).

  On the sender side (a), the creation data 11 is created based on the image data 10 for printing on the printed matter 20. The created data 11 includes printed material information 12 for forming the printed material 20, determination criteria for authenticity determination of the printed material, and a verification calculation waveform signal 15. The printed material information 12 includes image data 10, identification information adding region data 13 that can determine where the identification information is printed in the printed material, and identification dot pattern data 14 as identification information.

  The creation data 11 created on the sender side (a) is sent to the receiver side, and the identification information printed on the printed matter 20 using the identification information addition area data 13 and the verification calculation waveform signal 15 in the creation data 11. Are determined to determine whether or not the identification information is authentic, and the authenticity of the printed matter 20 is determined based on the determination result.

  Therefore, in order to determine the authenticity of the identification information and the printed matter, the receiver side acquires at least the identification information addition region data 13 and the verification calculation waveform signal 15 among the data included in the creation data 11.

  On the recipient side (e) to (g), in addition to the mode of receiving the printed matter itself depending on the distribution form of the printed matter, the printed matter information 12 data for printing the printed matter is received, and the printed matter is formed by printing on the recipient side. The printed matter can be acquired depending on the mode to be performed.

  In the present invention, on the receiver side (e) to (g), the printed data is acquired in any distribution mode, and the generated data, particularly the identification information addition region data 13 in the generated data and the verification calculation waveform signal. 15 is used to determine the authenticity of the identification information and the authenticity of the printed matter.

  The sender side (b) acquires the creation data from the sender side (a) and prints the authentic printed matter 20A. The printed printed matter 20A is printed based on the image data 10 in the printed matter information 12, and the identification information is provided by the identification dot pattern data 14 in the region defined in the printing unit 21 by the identification information addition region data 13. The printing unit 24 is printed. Therefore, genuine identification information is given to the printed matter 20A.

  The receiver side (e) acquires the printed material 20A from the sender side (b), while acquiring the creation data 11 from the sender side (a). On the receiver side (e), the scanning position of the magnetic sensor 30 is controlled based on the identification information adding region data 13 in the acquired creation data 11, and the identification information printing unit 24 in the printed matter 20A is scanned to make a determination. A detection waveform signal 25 is detected.

  The determination of the identification information is performed by reading the verification calculation waveform signal 15 from the created data 11 and comparing it with the detected detection waveform signal 25 for determination. Here, by confirming the coincidence between the verification calculation waveform signal 15 and the determination detection waveform signal 25, it is determined that the identification information is authentic, and it is determined that the printed material 20A is authentic.

  The sender side (c) sends the creation data 11 to the recipient side (f) without printing the printed matter. The receiver side (f) acquires the creation data 11 from the sender side (c). On the receiver side (f), the printed matter 20B is printed based on the printed matter information 12 in the acquired creation data 11. An identification information printing unit 24 is printed on the printed matter 20B in the identification information adding region 23 together with the printing unit 21.

  The receiver side (f) controls the scanning position of the magnetic sensor 30 based on the identification information addition area data 13 in the acquired creation data 11, and scans the identification information printing unit 24 in the printed matter 20B, The detection waveform signal for determination 25 is detected.

  The determination of the identification information is performed by reading the verification calculation waveform signal 15 from the created data 11 and comparing it with the detection waveform signal 25 for determination detected by scanning the printed material 20B. Here, by confirming the coincidence between the verification calculation waveform signal 15 and the determination detection waveform signal 25, it is determined that the identification information is authentic, and it is determined that the printed material 20A is authentic.

  The sender side (d) has shown the example which printed the printed matter illegally. In this case, the sender side (d) creates the printed matter 20C illegally. Here, the sender side (d) creates the printed material 20C illegally by printing using the illegally acquired image data or copying the printed material. Further, the identification information given to the unauthorized printed material 20C may take various forms, for example, a form in which no identification information is given, a form in which incorrect identification information is given, a form in which the identification information is correct but the grant area is not correct, etc. Can be considered.

  The receiver side (g) acquires the illegal printed material 20C from the sender side (d). On the receiver side (g), the scanning position of the magnetic sensor 30 is controlled based on the identification information addition area data 13 in the acquired creation data 11, and the area specified by the identification information addition area data 13 in the printed material 20C is determined. Scanning is performed to detect the detection waveform signal 25 for determination.

  At this time, in the form in which the identification information is not given, since the detection waveform signal for determination is not detected, the coincidence between the calculation waveform signal for verification 15 and the detection waveform signal for determination 25 cannot be confirmed, and the printed material 20c is illegal. It is determined that there is.

  Further, even in a form in which the identification information is correct but the application region is not correct, the determination detection waveform signal is not detected, and therefore, it is not possible to confirm the coincidence between the verification calculation waveform signal 15 and the determination detection waveform signal 25. The printed material 20c is determined to be illegal.

  Next, creation of creation data will be described with reference to FIGS. FIG. 3 is a flowchart for explaining creation of creation data, FIG. 4 is a diagram for explaining creation of creation data, and FIG. 5 is a diagram for explaining creation of a magnetic dot pattern. FIG. 6 is a diagram for explaining setting of dot density.

  First, image data 10 to be printed is acquired (S1), and the image data is expanded to acquire two-dimensional bitmap data 16 and color data 17. The color data 17 can be, for example, four colors, and bitmap data is formed for each color. For example, coordinates for printing cyan (xC1, yC1), ..., coordinates for printing magenta (xM1, yM1), ..., coordinates for printing yellow (xY1, yY1), ..., coordinates for printing black (xB1, yB1 ), ... etc. are created. The printer forms a printed material by driving the head based on this data to perform printing (S2).

  Based on the bitmap data 16 and the color data 17 formed in the step S2, candidate areas 22 into which the identification information is incorporated in the printing unit 21 are extracted. For example, the candidate area 22 can be extracted by designating a set color from the bitmap data 16. FIG. 4 shows an example in which the characters “C”, “M”, “Y”, and “B” are printed in cyan, magenta, yellow, and black, respectively, and black is selected from these colors. The printing area in the character “B” printed with black as the designated color is divided into a plurality of areas having a size for forming the identification dot pattern, and the area obtained by this division is a candidate area 22. Set as.

  In this example, the candidate area 22 is extracted using the print color as a condition. However, the present invention is not limited to this, and various conditions such as the position and the print density of the print unit may be set in the printed material. Good (S3).

  Next, the identification information provision area 23 to which identification information is imparted is selected from the plurality of extracted candidate areas 22. The identification information provision area 23 can be selected from among a plurality of candidate areas 22 based on, for example, a random number generated arbitrarily. By setting the selection of the identification information provision area 23 based on random information, the security of identification information can be improved. The position information of the selected identification information adding area 23 is set as the giving area data 13 (S4).

  The identification dot pattern data 14 of the present invention is composed of a magnetic ink dot pattern 14a for printing with magnetic ink and a non-magnetic ink dot pattern 14b for printing with non-magnetic ink, which are complementary to each other. Based on the identification dot pattern data 14, the magnetic ink dot pattern 14a is printed with magnetic ink, and the non-magnetic ink dot pattern 14b is printed with non-magnetic ink. Will be granted. This identification information is acquired by a waveform signal detected by scanning the magnetic characteristics of the printed identification information printing unit 24 with a magnetic sensor, and a waveform signal is acquired by calculation based on the identification dot pattern data 14. be able to. The waveform signal obtained from the identification dot pattern data 14 is obtained, for example, by calculating the magnetic distribution of the magnetic ink based on the identification dot pattern and calculating the waveform signal obtained when this magnetic distribution is scanned. Can do.

  In the present invention, the waveform signal obtained by this calculation is used as the verification calculation waveform signal 15 used for determining the authenticity of the identification information (S5).

  The creation data 11 is formed by the printed product information 12 including the image data 10, the identification information adding region data 13, the identification dot pattern data 14, and the verification calculation waveform signal 15 (S6).

  The creation data can be created by a computing device including a CPU that performs arithmetic processing, a creation program, a memory that stores calculation data and calculation results, and the like.

  The creation data 11 can be transmitted via a communication means in addition to being stored in a memory provided in the arithmetic device or a portable storage means.

  The magnetic ink dot pattern 14 a that forms the identification dot pattern can be formed based on the random information 40 and the dot density 41. FIG. 5 is a diagram for explaining the formation of the identification dot pattern.

  The magnetic ink dot pattern 14a is, for example, a pattern that determines which dot in a dot array arranged in a lattice pattern is a dot to be printed with magnetic ink, and can be determined by the number of dots and the arrangement position. .

  The dot density is a parameter that determines the number of dots to be printed with magnetic ink out of the total number of dots included in the magnetic ink dot pattern 14a. The inventor of the present application relates to a false acceptance rate (FMR: False Match Rate) that erroneously determines non-correct as true, and is related to the dot density and the set value. It has been found that by setting the density to a certain value or more, the false acceptance rate (FMR) becomes sufficiently small to be regarded as “0”.

  FIG. 6 schematically shows the relationship between the dot density [%] and the false acceptance rate (FMR: False Match Rate) [%]. FIG. 6 also shows a change due to the set value St between the waveform signals to be compared.

  In the relationship between the dot density [%] and the false acceptance rate (FMR: False Match Rate) [%], in the range where the dot density is low, the false acceptance rate (FMR) tends to decrease as the dot density increases. This tendency is stronger as the set value St is larger. Although not shown, when the dot density increases, the change in magnetic distribution due to the magnetic ink dot pattern decreases, and it is expected that it is difficult to identify the waveform signal obtained by scanning the magnetic sensor.

  Therefore, in the present invention, based on the relationship between the false acceptance rate (FMR) and the dot density, a dot density that is sufficiently small so that the false acceptance rate (FMR) can be regarded as “0” is set. Based on the above, the number of dots provided in the magnetic ink dot pattern of the identification dot pattern is determined. For example, the number of dots provided in the magnetic ink dot pattern can be obtained by multiplying the total dot number of the identification dot pattern by the set dot density.

  Next, the arrangement positions of the predetermined number of dots on the magnetic ink dot pattern are dispersed based on random information.

  Next, the printing of the identification information by the identification dot pattern will be described with reference to FIGS. FIG. 7 is a flowchart for explaining the printing of the identification information by the identification dot pattern, and FIG. 8 is an explanatory diagram for explaining the printing of the identification information by the identification dot pattern.

  First, the creation data 11 is acquired (S11), and the image data 10, the identification information addition area data 13, and the identification dot pattern data are acquired from the acquired creation data 11 (S12).

  The image data 10 is expanded to obtain two-dimensional bitmap data 16 and color data 17 and stored in the storage means (S13).

  Next, using the bitmap data 16 and the color data 17, for the non-magnetic ink dot pattern, the printing unit 21 is printed by repeating steps S14 to S18, while for the magnetic ink dot pattern, S15 and S19. , S20 is repeated to give identification information to the printing unit 21.

  The print positions are determined in order (S14), and it is determined whether the print position is within the identification information application area (S15).

  When the printing position is outside the identification information adding area (S15), the bitmap data 16 and the color data 17 at the printing position are read from the storage means (S16), and when the bitmap data 16 exists (S17). Then, the head specified by the color data 17 is driven for the bit and printing is performed (S18).

  On the other hand, if the printing position is within the identification information addition area (S15), the bitmap data 16 and the color data 17 of the printing position are read from the storage means, and if the bitmap data 16 exists, the color corresponding to that bit is read. When the data 17 is a set color (S19), printing is performed with magnetic ink when the dot is a magnetic ink dot pattern, and printing is performed with nonmagnetic ink when the dot is a nonmagnetic ink dot pattern (S20).

  As a result, the printed matter 20 in which the identification information printing unit 24 is formed in the identification information adding region 23 is formed.

  Next, determination of identification information will be described with reference to FIGS.

  FIG. 9 is a flowchart for explaining identification information determination, FIG. 10 is an explanatory diagram for explaining identification information determination, and FIG. 11 is for explaining threshold value setting used for identification information determination. FIG. 12 to 17 are diagrams for explaining each determination example.

  9 and 10, first, based on the identification information application region data 13, the identification dot pattern 14 is scanned by the magnetic sensor, and the detection waveform signal 25 for determination is detected. The scanning of the identification dot pattern by the magnetic sensor is performed by controlling the position of the magnetic sensor based on the identification information application region data 13. By controlling the position of the magnetic sensor based on the identification information adding area data 13, it is possible to detect whether the identification information is printed at any position on the printing unit 21 (S31).

  Further, the verification calculation waveform signal 15 is read from the created data 11, and the waveform is compared with the detection waveform signal 25 for determination and collated (S32).

  The waveform comparison between the verification calculation waveform signal 15 and the determination detection waveform signal 25 can be obtained by calculating the correlation coefficient St of both waveform signals.

  The correlation coefficient St can be expressed by the following formula (1).

  Note that pi and qi are waveform amplitudes at a sampling point i, and p * and q * are average values of all elements of p and q, respectively. The correlation coefficient S changes not with amplitude but with phase change (S33).

  The correlation coefficient S obtained by calculation is compared with a preset set value St to determine whether the identification information is true or not (S34).

  Here, the set value St described above will be described. The set value St used in the waveform comparison is a threshold value for determining the authenticity of the identification information using the correlation coefficient S as an index. The inventor of the present application has a false acceptance rate (FMR: False Match Rate) that erroneously determines non-correctness and a false rejection rate (FNMR: False Non-Match Rate) that erroneously determines authenticity as incorrect. This relationship indicates a reverse change in which one increases when the set value St changes, and the other decreases, and it has been found that there is a so-called trade-off relationship. FIG. 11A is a diagram showing the relationship between the false acceptance rate (FMR) and the false rejection rate (FNMR) with respect to the change in the set value St. In addition, this figure shows the outline for demonstrating a tendency, Comprising: A magnitude relationship is not shown correctly.

  The false acceptance rate (FMR) decreases as the set value St increases, and the false rejection rate (FNMR) decreases as the set value St decreases. Accordingly, in FIG. 11 (a), the setting value St for reducing both the false acceptance rate (FMR) and the false rejection rate (FNMR) intersects the false acceptance rate (FMR) curve and the false rejection rate (FNMR) curve. Near the point to be. In the present invention, in the determination of the authenticity of the identification information performed using the correlation coefficient S, a setting value at which both the false acceptance rate (FMR) and the false rejection rate (FNMR) become small is determined as St, and the correlation coefficient S is the set value. If greater than St, it is determined to be authentic.

  The false rejection rate (FNMR) at this time depends on the positional deviation between the identification information printed on the printed matter to be determined and the sensor that reads the identification information. FIG. 11B shows a state in which the false rejection rate (FNMR) with respect to the set value St changes due to the displacement of the magnetic sensor. The false rejection rate (FNMR) increases as the positional deviation of the magnetic sensor increases. FIG. 11C shows the false rejection rate (FNMR) with respect to the set value St.

  11 (b) and FIG. 11 (c), the sensor position from FIG. 11 (b) with respect to the set value St at which the false rejection rate (FNMR) shown in FIG. An erroneous rejection rate (FNMR) using deviation as a parameter can be determined.

  From this relationship, in order to determine a certain false rejection rate (FNMR) with respect to a set value St at which the false rejection rate (FNMR) can be regarded as sufficiently small, an erroneous rejection rate that intersects with the alternate long and short dash line in FIG. It is necessary to suppress the positional deviation of the magnetic sensor so that the value of (FNMR) becomes the set value.

  In addition, when there is a limit to the accuracy with which the magnetic sensor position shift is suppressed, the error rejection rate (FNMR) curve determined by the position shift of the magnetic sensor determines the phase at that time. A value of the false acceptance rate (FMR) determined by the relation number St is determined, and it is determined whether the false acceptance rate (FMR) is within an allowable range.

  Hereinafter, each determination example will be described with reference to FIGS.

  FIG. 12 shows the relationship between data creation and determination. On the data creation side, creation data 11 is created based on the image data, random information, and dot density data. As described above, the creation data 11 includes image data, identification information application region data, printed matter information including identification dot pattern data, and a verification calculation waveform signal obtained by calculation from the identification dot pattern data.

  On the determination side, at least the identification information application region data and the verification calculation waveform signal 15 of the generation data 11 generated on the data generation side are acquired, and the detection information waveform for determination is obtained by scanning the identification information from the printed matter 20 to be determined by a magnetic sensor. The signal 25 is detected, and the verification is performed by comparing the verification calculation waveform signal 15 with the detection waveform signal 25 for determination.

  A first determination example will be described with reference to FIG. The first determination example is an example of determining an unauthorized printed matter obtained by copying.

  When an unauthorized printed material 20a is formed by copying the printed material 20, the identification information printing unit 24 is not formed on the unauthorized printed material 20a.

  On the determination side, based on the identification information addition area data, the identification information addition area of the unauthorized printed material 20a is scanned with a magnetic sensor. Since the identification information printing unit 24 is not formed in the identification information addition region, the printed product 20a obtained illegally by copying cannot obtain the detection waveform signal for determination from the magnetic sensor.

  When the verification calculation waveform signal and the determination detection waveform signal are collated, since the detection waveform signal for determination is not detected from the magnetic sensor, the result is a mismatch and it is determined to be illegal.

  A second determination example will be described with reference to FIG. The second determination example is an example of determining a printed matter formed by illegally obtaining image data and a verification calculation waveform signal.

  When the image data is illegally obtained, the printed matter 20b can be printed based on the illegally obtained image data. In this case, the identification information printing unit 24 is not formed on the unauthorized printed material 20b.

  On the determination side, based on the identification information addition area data, the identification information addition area of the unauthorized printed material 20b is scanned with a magnetic sensor. Since the identification information printing unit 24 is not formed in the identification information adding region, the printed product 20b obtained illegally by copying cannot acquire the detection waveform signal for determination from the magnetic sensor.

  When the verification calculation waveform signal and the determination detection waveform signal are collated, since the detection waveform signal for determination is not detected from the magnetic sensor, the result is a mismatch and it is determined to be illegal.

  Further, when the verification calculation waveform signal or the identification dot pattern is illegally obtained together with the image data, an unauthorized printed matter 20b is formed by the image data, and the identification information printing unit 24 is formed on the unauthorized printed matter 20b. There is a risk of being. If the identification dot pattern is obtained illegally, there is a risk that identification information will be given in the print section. However, in this case, since there is no identification information addition area data relating to the position to which the identification information is added, it can be added to any position in the printing unit, but is determined by the identification information addition area data. It is difficult to apply the correct position. In FIG. 14, although the identification information printing part 24 is formed in the printing part of the printed matter 20b, the application position is not correct.

  On the determination side, based on the identification information addition area data, the identification information addition area of the unauthorized printed material 20b is scanned with a magnetic sensor. Since the identification information printing unit 24 is not formed in the identification information provision area, the printed material 20b obtained by illegally obtaining the image data cannot obtain the detection waveform signal for determination from the magnetic sensor.

  When the verification calculation waveform signal and the determination detection waveform signal are collated, since the detection waveform signal for determination is not detected from the magnetic sensor, the result is a mismatch and it is determined to be illegal.

  A third determination example will be described with reference to FIG. The third determination example is an example of determining a printed matter formed by illegally obtaining image data and identification information adding area data.

  When the image data is obtained illegally, the printed matter 20c can be printed based on the illegally obtained image data. In this case, although the position where the identification information is given can be known from the identification information addition area data, the identification dot pattern data is unknown, so the identification information printing unit 24 is not formed on the unauthorized printed matter 20c, or Thus, the identification dot pattern data created irrespective of the genuine identification dot pattern data is given.

  In FIG. 15, although the identification information printing part 24 is formed at the correct application position in the printing part of the printed matter 20c, the identification dot pattern is not correct.

  On the determination side, based on the identification information provision area data, the identification information provision area of the unauthorized printed matter 20c is scanned by the magnetic sensor. Since the identification information of the identification information printing unit 24 formed in the identification information adding region is not correct in the printed material 20c in which the image data is obtained illegally, the determination detection waveform signal cannot be acquired from the magnetic sensor.

  When the verification calculation waveform signal and the determination detection waveform signal are collated, the determination detection waveform signal detected from the magnetic sensor does not match the verification calculation waveform signal, and is determined to be illegal.

  A fourth determination example will be described with reference to FIG. The fourth determination example is an example in which image data, identification information addition region data, and a verification calculation waveform signal are obtained illegally, and a printed matter formed based on this is determined.

  When the image data is obtained illegally, the printed matter 20d can be printed based on the illegally obtained image data. In this case, although the position to which the identification information is given can be known from the identification information addition area data, the identification dot pattern data is unknown depending on the verification calculation waveform signal. No. 24 is formed, or identification dot pattern data created irrespective of genuine identification dot pattern data is given.

  On the determination side, based on the identification information provision area data, the identification information provision area of the unauthorized printed matter 20d is scanned by the magnetic sensor. The printed material 20d obtained illegally by copying does not have the identification information printing part 24 formed in the identification information adding region or is given identification information by an irrelevant identification dot pattern. Therefore, the detection waveform signal for determination cannot be acquired from the magnetic sensor.

  When the verification calculation waveform signal and the determination detection waveform signal are collated, the determination detection waveform signal detected from the magnetic sensor does not match the verification calculation waveform signal, and is determined to be illegal.

  A fifth determination example will be described with reference to FIG. The fifth determination example is an example in which even a genuine user is detected illegally if the identification information is not held.

  When the image data is included, the printed matter 20e can be printed based on the image data. Here, when the identification information is not held, the identification information printing unit 24 is not formed on the printed material 20e.

  On the determination side, based on the identification information addition area data, the identification information addition area of the unauthorized printed material 20e is scanned with a magnetic sensor. In the printed material 20e, since the identification information printing unit 24 is not formed in the identification information application region, the determination detection waveform signal cannot be acquired from the magnetic sensor.

  When the verification calculation waveform signal and the determination detection waveform signal are collated, since the detection waveform signal for determination is not detected from the magnetic sensor, the result is a mismatch and it is determined to be illegal.

  In each of the above-described examples, an example in which the printing unit to which the identification dot pattern is applied is printed with a single color, but printing may be performed with multiple colors. FIG. 18 shows an example in which the identification dot pattern is printed in multiple colors. Here, an example is shown in which the identification dot pattern is printed in each color of yellow, magenta, cyan, and black.

  FIG. 18A shows an example in which the identification dot pattern is formed with stripes of yellow, magenta, cyan, and black from the left. These color stripes are divided into a magnetic ink dot pattern and a non-magnetic ink dot pattern. The magnetic ink dot pattern is printed with magnetic ink, and the non-magnetic ink dot pattern is printed with non-magnetic ink.

  FIG. 18B shows a magnetic ink dot pattern for printing with yellow magnetic ink, and FIG. 18C shows a non-magnetic ink dot pattern for printing with yellow non-magnetic ink. Similarly, FIG. 18D is a magnetic ink dot pattern for printing with magenta magnetic ink, and FIG. 18E is a non-magnetic ink dot pattern for printing with magenta non-magnetic ink. f) is a magnetic ink dot pattern printed with cyan magnetic ink, FIG. 18G is a non-magnetic ink dot pattern printed with cyan non-magnetic ink, and FIG. 18H is a black magnetic ink pattern. FIG. 18 (i) is a non-magnetic ink dot pattern for printing with black non-magnetic ink.

  Here, the print portions of each color are formed in stripes, but the present invention is not limited to this, and the present invention can also be applied to a case where the print portions of each color are randomly distributed.

  The present invention is not limited to printed matter printed on printing paper such as paper, but can be applied to printed matter formed by printing image data on the surface of various materials such as resin and metal.
