Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a verification system that performs matching by recognizing a predetermined identification management code to be formed.
[0002]
[Prior art]
Conventionally, for example, in the production of a form, a form having different print information for each customer has been performed in a series of printing processes. At that time, in order to match the target customer and the print information, an identification management code such as a barcode or a management number is printed at a predetermined position on the form, and the printed identification management code and information are read. In general, a target is read out from a database (DB) in which names and print information are associated with each other and compared. Also, when collating by binding multiple forms for each customer or collating them together, an identification management code must be printed on each form in advance in order to match matching targets. Has also been done.
[0003]
On the other hand, the identification management code is essentially unnecessary for the customer, and is necessary only when creating a form or collating. Therefore, a technique for printing such an identification management code with so-called stealth ink that is invisible and is visible when irradiated with excitation light having a predetermined wavelength is known in the following patent documents and the like.
[0004]

Japanese Patent Laid-Open No. 2001-18870
[Problems to be solved by the invention]
However, the printing means using the stealth ink is expensive, and the stealth ink is a consumable product and the ink itself is expensive, leading to an increase in running cost and eventually the product has to be expensive. There is a problem.
[0006]
Therefore, the present invention has been made in view of the above problems, and provides a verification system that forms an identification management code without impairing the design of the object to be verified and enables matching with the identification management code at a low cost. Objective.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the inventor of the present application has disclosed a laser half-cut technique for cutting (Japanese Patent Laid-Open No. 2002-104437, etc.) and a visible watermark by laser half-cut for preventing counterfeiting. By using a forming technique (Japanese Patent Laid-Open No. 10-236000, etc.), it is found that an identification management code can be formed with difficulty in visual observation, and the formed identification management code can be imaged as image information to enable verification. Was devised.
[0008]
That is, according to the first aspect of the present invention, the storage means storing the different print information for each individual and the related identification management code data for each individual object, and the individual print information based on the data of the storage means Is printed, and the corresponding identification management code is formed in a portion where the identification management code is formed at least on the printed body on which the corresponding identification management code is difficult to see by half-cutting with laser light. The printing information and the identification management code are recognized from the imaging unit that irradiates the imaging light of the normal wavelength that enables imaging, and the imaging data captured by the imaging unit, and based on the identification management code It is configured to include collation processing means for reading out corresponding print information data from the storage means and comparing and comparing with the recognized print information.
[0009]
In the invention of claim 2, the identification management code corresponding to each individual is formed in a portion where the identification management code of the plurality of pieces to be collated is formed with a laser beam being half-cut and difficult to visually recognize. , Each of the identification units based on the imaging data captured by the imaging unit with respect to each of the objects to be collated; And a collation processing means for recognizing the management code and comparing and collating whether or not it is a collation target.
[0010]
According to a third aspect of the present invention, at least the identification management code is picked up by the image pickup means based on a transmission amount of the irradiated image pickup light or a shadow generated by the image pickup light.
[0011]
Thus, it was obtained by forming an identification management code corresponding to the object to be verified of the printing medium in a difficult-to-view manner by half-cutting with laser light, and irradiating the identification management code with imaging light of a normal wavelength. The identification management code is recognized from the image data, and the corresponding print information is read from the storage means and compared with the print information recognized from the image data. That is, since the identification management code is formed by half-cutting with a laser beam, the identification management code that is difficult to see without using expensive stealth ink that is consumed at any time as before does not impair the design of the object to be verified. Therefore, it is possible to perform matching between printed print information and original data at a low cost.
[0012]
In addition, identification management codes corresponding to a plurality of objects to be collated are formed in a difficult-to-view manner by half-cutting with laser light, and each identification management code is obtained by irradiating with imaging light of a normal wavelength. The identification management code is recognized from the captured image data, and corresponding collated objects are compared and collated. That is, since the identification management code is formed by half-cutting with a laser beam, the identification management code that is difficult to see without using expensive stealth ink that is consumed at any time as before does not impair the design of the object to be verified. Therefore, it is possible to match the corresponding objects to be collated at low cost.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a configuration diagram of a verification system according to the present invention. FIG. 1A is a configuration diagram of a collation system, and FIG. 1B is an explanatory diagram of identification management code formation. In the present embodiment, the collation target is described as a form. However, the present invention can be applied to a label or the like, and the collation target may be a continuous state or a single piece state.
[0014]
In FIG. 1 (A), the collation system 11 is provided with an imaging means including an imaging camera 13 and an illumination unit 14A (14B) for imaging a form 12 on which an identification management code described later is formed. The collation processing unit 15 performs collation, and the collation processing unit 15 can freely access a customer database (DB) 16.
[0015]
In the form 12, as shown in FIG. 1B, individual print information of a customer name 32 and correspondence information 33 corresponding to the customer is printed at a predetermined position on a paper 31 as a base, and identification management is performed. A code ID 34 (for example, “1234567” as a management number) is difficult to see with a half-cut 35 by a laser beam. In other words, the half cut 35 is difficult to view because the surface and the inside of the form 12 have the same color. The customer name 32, the correspondence information 33, and the ID 34 are printed and formed in accordance with individual (customer) information stored in a customer DB 16 described later.
[0016]
As the imaging camera 13, for example, a commonly used CCD camera can be used. Moreover, although the illumination part 14A is arrange | positioned with respect to the form 12 in the surface facing the imaging camera 13, you may arrange | position the illumination part 14B on the same surface as the said imaging camera 13 as shown with the broken line on drawing. That is, when the illumination unit 14A is arranged on the opposite surface of the form 12, the imaging camera 13 can capture images with a large amount of imaging light transmitted from the illumination unit 14A, and the illumination unit 14B is on the same plane. In the case of being arranged, it is possible to take an image by a shadow generated by the imaging light. The illumination unit 14A (14B) irradiates imaging light having a normal wavelength, and the normal wavelength means that generally used visible light is sufficient and does not require a specific wavelength. .
[0017]
The collation processing means 15 recognizes the print information (customer name 32, correspondence information 33) and ID 34 from the image data captured by the imaging camera 13, and responds from the customer DB 16 which is a storage means described later based on the ID 34. The print information data is read out and compared with the recognized print information, and is appropriately provided with a collation control means 21, a bus 22, an interface (IF) 23, an imaging data acquisition means 24, a collation means 25, and a display means 26.
[0018]
The collation control means 21 controls the system and stores a control program. The IF 23 inputs at least imaging data from the imaging camera 13. The imaging data acquisition unit 24 temporarily stores imaging data from the imaging camera 13 and serves as a work area for verification processing by the verification unit 25. Although the details will be described with reference to FIG. 2, the collation unit 25 recognizes the print information (customer name 32, correspondence information 33) and ID 34 from the image data captured by the imaging camera 13, and the customer DB 16 based on the ID 34. The corresponding print information data is read out and compared with the recognized print information. The display means 26 is provided as appropriate, and displays the collation result by the collation means 25.
[0019]
The customer DB 16 stores different print information (customer name 32, correspondence information 33) for each individual and related ID 34 data for each individual object, and the form 12 is printed according to the print information. Accordingly, it is difficult to see by half-cutting with a laser beam, and an example thereof is shown in FIG.
[0020]
Here, FIG. 2 shows an explanatory diagram of the collation means and the customer DB in the collation processing means of FIG. FIG. 2A is a block configuration diagram of an example of the collating unit 25, and FIG. 2B is an explanatory diagram of an example of information stored in the customer DB 16. In FIG. 2A, the collation means 25 includes an image information recognition means 41, a data reading means 42, and a comparison collation means 43 as appropriate.
[0021]
The image information recognizing means 41 performs, for example, area division on the work area of the imaging data acquisition means 24 to identify the positions of the customer name 32, the correspondence information 33, and the ID 34, The customer name 32 is recognized, the correspondence information 33 is recognized, and the ID 34 is recognized. The data reading means 42 reads a corresponding customer name and correspondence information from the customer DB 16 based on the recognized ID 34 and temporarily stores it in the work area of the imaging data acquisition means 24. The comparison / collation means 43 compares the recognized customer name 32 and correspondence information 33 with the customer name 32 and correspondence information 33 read from the customer DB 16 and displays the result on the display means. Further, the collation unit 25 appropriately creates a log file of the collation result and stores it in the customer DB 16 (may be another storage unit).
[0022]
In FIG. 2B, the customer DB 16 stores, for example, IDs, customer names, and print data files (file names) assigned to the customers with respect to all customers, as well as the print data file. Print data (corresponding information 33, for example, first print data for the front surface, second print data for the back surface, etc.) is stored separately or hierarchically, for example.
[0023]
Therefore, FIG. 3 shows a flowchart of collation of the collation system according to the present invention. In FIG. 3, first, the image data acquisition means 24 acquires imaging data from the imaging camera 13 (step (S) 1). Therefore, the image information recognition unit 41 of the collation unit 25 performs, for example, area division based on the acquired imaging data to identify the positions of the customer name 32, the correspondence information 33, and the ID 34, and recognizes the customer name 32. The correspondence information 33 is recognized, and the ID 34 is recognized and specified (S2).
[0024]
Subsequently, the data reading means 42 of the matching means 25 reads the corresponding customer name and corresponding information from the customer DB 16 based on the identified ID 34 (S3). Therefore, the comparison and collation means 43 of the collation means 25 compares and collates the identified customer name 32 and correspondence information 33 with the customer name 32 and correspondence information 33 read from the customer DB 16 (S4). Then, the collation result is displayed on the display means 26, and a log file of the collation result is appropriately created and stored in the customer DB 16 or the like (S5).
[0025]
In this way, the ID 34 is formed on the form 12 by half-cutting with the laser beam, so that the form of the ID 34 that is difficult to see without using expensive stealth ink that is consumed at any time as before can be created. It can be formed without damage, and can be imaged by the imaging camera 13 with imaging light of a normal wavelength by the illumination unit 14A (14B) at the time of collation, thereby matching the printed information and the original data printed at low cost. It will be able to be done.

The IF 55 sends drive control signals to the first and second printing means, the laser irradiation means, and the imaging means, inputs imaging data from the imaging means, and data related to predetermined printing read from the customer DB 16 Enter. The print file creation means 56 reads out data of information to be printed on the verification target form (described in FIG. 5) from the customer DB 16 and creates a print file for printing.
[0028]
The first print control means 57 drives and controls the first print means, and sends print data by a corresponding method based on the print file created by the print file creation means 56. The laser processing data creating means 58 creates processing data for forming the ID 34 corresponding to the form to be printed with the half-cut 35 so that it is difficult to see. The laser irradiation control means 59 drives and controls the laser irradiation means based on the created processing data. The second print control means drives and controls the first print means, and sends out print data by a corresponding method based on the print file created by the print file creation means 56.
[0029]
Here, FIG. 5 shows an explanatory diagram of printing and collation in the printing system of FIG. In FIG. 5A, the first printing means 61A and the laser irradiation means 62 are arranged on the first printing means 61A side, and the print information is printed on one side (the front side) of the continuous form 63, ID 34 is formed. The laser irradiating means 62 includes only a machining head in the drawing, but includes a laser light generating means and a scanning means for controlling the irradiation position of the laser light.
[0030]
In the continuous form 63, marginal portions 71A and 71B corresponding to the conveying means are provided so as to be separable by a perforation line or the like, and a cutting line 72 for cutting each corresponding customer is formed. Print information corresponding to each customer (customer name 32 and correspondence information 33 as shown in FIG. 1) is printed by the first printing means 61A in the area divided by the cutting line 72 to correspond to the customer. The ID 34 thus attached is formed by the laser irradiation means 62. Then, after a predetermined processing step, the form 12 as shown in FIG. 1B is obtained by cutting along the cutting lines 72.
[0031]
FIG. 5B shows a customer printed on one side (front side) with respect to the other side (back side) in the continuous form 63 in which the print information is printed and the ID 34 is formed in FIG. 5A. The second printing means 61B for printing on the back surface is arranged. Note that the second printing unit 61B (second printing control unit 60 in FIG. 4) is not required when the back side is not printed.
[0032]
The imaging camera 13 is disposed above the front surface of the second printing unit 61B, and the illumination unit 14A is disposed below the continuous form 63. When the illumination unit 14B is disposed on the same side as the imaging camera 13, the second printing unit 61B may be disposed below the continuous form 63.
[0033]
FIG. 6 shows a flowchart of printing and collation in the printing system of FIG. 6A is a flowchart of the printing process corresponding to FIG. 5A, and FIG. 6B is a flowchart of the matching process and the printing process corresponding to FIG. 5B. 6A, first, the print file creation unit 56 of the print processing unit 52 acquires first print data to be printed on one side (front side) of the continuous form 63 from the customer DB 16 (S11).
[0034]
The print file creation unit 56 creates a first print file based on the acquired first print data and sends it to the first printing unit 61A. The customer name 32 and the correspondence are created on one side of the continuous form 63. The print information of the information 33 is sequentially printed (S12). Further, in the laser processing data creating means 58, the ID 34 of the corresponding customer is extracted from the first print data acquired from the customer DB 16 to create laser processing data (S13), and the laser irradiation means 62 is based on the laser processing data. The laser irradiation means 62 is controlled and driven (S14). By performing half-cut processing at the corresponding position on one side of the continuous form 63 with this laser processing data (ID data), an ID 34 that is difficult to see as shown in FIG. 1B is formed.
[0035]
On the other hand, in FIG. 6B, the continuous form 63 having the print information (customer name 32 and correspondence information 33) formed on one side in FIG. The imaging data from is acquired (S21). Therefore, in the collation system 15, based on the acquired imaging data, for example, region division is performed to identify the positions of the customer name 32, the correspondence information 33, and the ID 34, the customer name 32 is recognized, and the correspondence information 33 is recognized. ID 34 is recognized and specified (S22).
[0036]
Subsequently, the corresponding customer name and correspondence information are read from the customer DB 16 based on the identified ID 34 (S23). Therefore, the identified customer name 32 and correspondence information 33 are compared with the customer name and correspondence information read from the customer DB 16 (S24). As a result of the comparison and collation (S24), if they match, the second print data for the other side (back side) is obtained from the customer DB 16 based on the ID 34 specified by the print file creation means 56, a print file is created and the second print data is created. The print information corresponding to the back surface of the continuous form 63 is printed by sending it to the second printing means 61B. Then, if the result of comparison and collation (S25) does not match, the fact is appropriately displayed on the display means (26), and a log file of the collation result is created and stored in the customer DB 16 or the like (S27). .
[0037]
In this way, the ID 34 of the corresponding customer is formed on the continuous form 63 (form 12) by half-cutting with the laser beam, so that it is difficult to view without using expensive stealth ink that is consumed as needed. The ID 34 can be formed without damaging the design of the form, and can be imaged by the imaging camera 13 with imaging light of a normal wavelength by the illumination unit 14A (14B) at the time of collation. Matching with data can be performed at low cost, and even when the corresponding print information is printed on the other side (back side) after matching, matching with the print information on one side (front side) is also possible. It is intended.
