DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the present invention based on the embodiment shown in FIG.
The invention and the third invention will be described. The embodiment of FIG. 1 shows a case where a pachinko prepay card 1 is applied as a security, and having securities individual information 2 such as a serial number and a manufacturing date is the same as a known prepaid card. However, in the embodiment of the present invention, the securities individual information 1 is printed and recorded on the securities (prepay card 1) by applying a two-dimensional code. That is, a magnetically readable two-dimensional code print record (for example, an alphanumeric character, a symbol, a code, etc. is printed by magnetic ink by two-dimensional code conversion), an optically readable two-dimensional code print record (for example, an alphanumeric character , Symbols, codes, etc. are printed and recorded with printing ink by two-dimensional code conversion). In this case, the securities individual information 2 is used as the printing with invisible ink instead of the general printing ink (for example, black printing with a dot printer, red ribbon printing, ink printing with any color of an ink jet printer). The existence and content of can be unclear. In addition, a printing area 3 of the securities individual information 2 is set, the printing area 2 is printed with an ink that absorbs a specific color wavelength, and the securities individual information 2 emits light at a specific color wavelength (for example, black infrared emission). ink)
Print individual securities information 2 by printing with area 2
It is possible to record in a masked state.

The securities individual information 2 is preferably displayed in a continuous string of alphanumeric characters and the like, and the alphanumeric characters and the like are preferably selected randomly. . For example, A12000B *
11, A12000B * 12 ... A12000B
* 20 The serial number etc. are not displayed continuously, but A183M7412 * 06, 19587G00
B1 * 1 ...? It is desirable to use a randomly selected sequence such as 20 * A120X542.

Next, according to the present invention, securities individual information 2
Is characterized by the application of a two-dimensional code and the inclusion of accidental change data formed by a printed record containing random elements, which will be described.

Unlike a conventional one-dimensional code such as a bar code, the two-dimensional code has HL binary marks arranged in a matrix and corresponds to a field character code, a multi-stage arranged bar code and the like. As the two-dimensional code A shown in FIG. 3, Japanese Patent Publication No. 8-21054, Japanese Patent Publication No. 8-16915, and Japanese Patent Publication No. 8-16916 “identification code” according to the invention of the present applicant are applied.

In the two-dimensional code A, an auxiliary area 12 is formed around a data area 11 in which HL binary marks K are arranged in a matrix, and the data area 11 and the auxiliary area 1 are formed.
2 is surrounded by an X-axis base line 14, a Y-axis base line 13 and a corner mark 15 to form unit data. Unit division 16 for recording the binary mark K for the data area 11
By increasing the number of, the amount of information in the data area 11 can be increased in series. Since there is a large amount of information, all cards can be specified with a single or a small number of unit data as the information amount equal to or greater than the number of issued cards. Also, the auxiliary area 1
It is easy to use the auxiliary area such as recording the encrypted data for selecting the arrangement of the unit areas of the data area in 2.

When a plurality of unit data of the two-dimensional code A is used or when additional printing is performed every time the prepaid card 1 is used, as shown in FIG. 4, the auxiliary area 12 of the unit data of the two-dimensional code A is used. Further, the base line 13 of the unit data of the adjacent (additional) two-dimensional code A is overprinted to form the overlapping range Q, which makes it difficult to recycle the used card (auxiliary area for initial printing). It is difficult to completely erase the additional print, leaving 12.

Next, the recording of the securities individual information 2 containing the accidental change data formed by the print recording including the contingent element will be described. The above two-dimensional code A is
Unlike conventional one-dimensional codes such as barcodes, the HL binary marks are arranged in a matrix, so that the information printed and recorded on the securities (prepaid card) 1 has a two-dimensional code. By randomly changing the print position, the print angle, the density distribution of each data between the two-dimensional codes, the data position, the shape, etc., the random element is inherent.

As a means for accidentally changing the printing position of the two-dimensional code, the printing angle, the density distribution of each data between the two-dimensional codes, the data position, the shape, etc., the above-mentioned two-dimensional code A is used as a security ( When printing on the prepaid card 1 by the printer, the securities and the print head of the printer are vibrated and shaken relative to each other. At this time, the vibration period, the vibration width, the relative position, etc. are changed randomly (irregularly) by mechanically vibrating and oscillating, and the accidental change data is inherent. When printing on a printer, the securities (prepait card) 1 is vibrated up and down, left and right, and back and forth, so that they vibrate relatively.
Although it can be shaken, the object of the present invention can also be achieved by vibrating and shaking the printer head when printing with a computer dot printer or ink jet printer.

The accidental change data based on the accidental change of the printing position, the printing angle of the two-dimensional code, the density distribution of each data between the two-dimensional codes, the position and shape of the data, etc. Although it is included in the pet card 1), when reading the two-dimensional code A in FIG. 3, the printing position, the printing angle of the two-dimensional code, the density distribution of each data between the two-dimensional codes, the data position, the shape, etc. In case of accidental change, the position and density of the unit area of the data area 11 is corrected to detect the unit data, and the correction parameter is recorded in the auxiliary area 12. The corrected unit data or the correction parameter recorded in the auxiliary area 12 can be applied as the accidental change data.

The first invention of the present application discovers counterfeit securities by detecting the above-mentioned accidental change data for each securities (prepaid card) 1.
Accidental change data (corrected unit data, or correction parameters recorded in the auxiliary area 12) for securities individual information 2 (for example, securities serial number) for each securities (prepay card) 1, By recording the information in the management center's computer, it is possible to match the securities individual information about each securities with the accidental change data about each securities by the management center's computer when judging the authenticity of securities. it can. When accidental change data is not recorded in the computer of the management center, the individual securities information (eg, security serial number) 2 and the incidental change data that are inherent in the identification of securities are sold at a store or a fixed area. The existence of a securities (preparate card) 1 in which the securities individual information (for example, securities serial number) 2 and the incidental change data that are inherent are the same by inputting into a computer that manages a certain chain range ( Copy securities) will be detected.

Next, the second and fourth inventions of the present application will be described with reference to FIG. The accidental change data 4 inherent in the securities individual information 2 is recorded and displayed on the securities paper on the securities (prepaid card) 1 in FIG. 1 (for example,
A two-dimensional code A ') containing the accidental change data shown in FIG. As the accidental change data 4, in the two-dimensional code A ′ of FIG. 4, the corrected unit data or the correction parameter recorded in the auxiliary area 12 is included.
It can be a modified two-dimensional code. When recording the accidental change data 4, the accidental change data is printed and recorded in the same manner as the inherent securities individual information 2. That is, a magnetically readable two-dimensional code print record and an optically readable two-dimensional code print record are made. In this case, the presence and content of the accidental change data (printing by the corrected two-dimensional code) 4 can be made unclear as printing by the invisible ink instead of the normal general printing ink. Further, like the print area 3 of the securities individual information 2, the print area 5 of the accidental change data 4 is set, and the print area 5 is printed with an ink that absorbs a specific color wavelength, or with a ground color print with a black ink. However, by printing the securities individual information 2 with an ink that emits light with a specific color wavelength (for example, black infrared light emitting ink), the accidental change data 4 can be recorded in a mask state by the printing area 5.

In carrying out the second invention of the present application, the securities (prepaid card) 1 on which the accidental change data 4 is recorded and displayed is used. Internal accidental change data and accidental change data recorded and displayed on securities 4
Then, the counterfeit securities are discovered by comparing the two with the accidental change data of both parties.

[0018]

According to the first and third inventions of the present application, individual securities individual information in which accidental change data is inherent by printing and recording a two-dimensional code on a security and including a random element. By characterizing securities individually by forming a copy, it is possible to quickly discover the existence of copy securities and minimize the damage caused by counterfeit securities, and by incorporating accidental change data. , Making counterfeit securities unmanufacturable in terms of cost (offset printing requires the production of a large number of sheets in terms of cost). The second invention and the fourth invention of the present application collate the accidental change data information on the securities with the accidental change data inherent in the securities individual information, and find the counterfeit securities by the disagreement between the two. Counterfeit securities can be detected without the need for a computer such as a management center.
