Description

Akira Itoda Securities detection method and securities with counterfeit prevention function

The present invention relates to countermeasures against counterfeiting of securities such as gift certificates, tickets, and bridge cards for providing goods and services. Background art

For such securities, counterfeit copies are increasing due to the sophistication of copy technology. As countermeasures against counterfeiting of securities, individual information (serial number, production unit number, encryption code, etc.) is recorded on each security.

When detecting a counterfeit copy of a security, the individual security individual information is compared with the record of the computer that records the individual security individual information, thereby detecting the same security individual information and reproducing the counterfeit. However, there is a problem that cannot be practically applied to gift certificates, pre-paid cards, etc., which are low in comparison with the cost of records and the prices of securities. is there.

An object of the present invention is to make it difficult to duplicate securities by increasing the cost of duplicating individual securities, and to facilitate detection of counterfeit duplication by recording individual securities individual information. Disclosure of

In the first invention of the present application, upon issuance of securities, individual security information in which accidental change data is embedded is formed by converting a two-dimensional code and printing a record including contingent elements on the securities. In order to determine the authenticity of a security, the individual security information of each security and the accidental change date of each security Collate with. Discover forged securities by discriminating fraudulent data from accidental change.

In the second invention of the present application, in addition to the first invention, the underlying accidental change data and the security are recorded and displayed on the securities paper to determine the authenticity of the security. It is compared with the accidental change data recorded and displayed on the paper. Discovers counterfeit securities by judging fraudulent data of accidental change.

The third invention of the present application is characterized in that a two-dimensional code is applied to a security, and the security has individual security information formed by a printing record including a contingent element and containing accidental change data. .

3 BEST MODE FOR CARRYING OUT THE INVENTION

The first invention and the third invention of the present application will be described based on the embodiment shown in FIG.

In the embodiment shown in Fig. 1, the case where a pachinko pre-card 1 is applied as a security is shown. The same as the private card, but in the embodiment of the present invention, the security individual information 1 is printed on the security (the private card 1) by applying a two-dimensional code. I do. That is, magnetically readable two-dimensional code printing record (for example, printing of alphanumeric characters, symbols, codes, etc. by magnetic ink by two-dimensional code conversion), optically readable secondary recording Original code printing record (for example, printing of alphanumeric characters, symbols, codes, etc. by printing ink by two-dimensional code conversion). In this case, the general printing ink (for example, black and red ribbon printing on a dot printer, ink printing of any color on an ink jet printer) can be used. Alternatively, the existence and content of the individual securities information 2 can be obscured by printing with an invisible ink. In addition, the printing area 3 of the securities individual information 2 is set, the printing area 2 is printed with an ink absorbing a specific color wavelength, and the securities individual information 2 is emitted with the specific color wavelength. By printing with an ink (for example, a black infrared ray emitting ink), the individual securities information 2 can be recorded in a mask state by the print area 2.

It is desirable that the individual security information 2 be displayed in a continuous column of alphanumeric symbols and the like, and that the alphanumeric symbols and the like be randomly selected and arranged. ,, For example, A 1200 B water 11, A 12 000 B * 12----Α 12000 Β * 20 1 83 Μ 74 1 2 * 06, 1 9 5 8

It is desirable to use a randomly selected sequence such as 7 G 0 0 B 1 * 1? 20 * Α 120 542 542. Next, according to the present invention, the individual security information 2 is characterized by the fact that the two-dimensional code is applied and the accidental change data is formed by the printing record including the contingent element, This is explained.

The two-dimensional code is different from the conventional one-dimensional code such as a bar code in that the binary mark of the HL is matrix-arranged. One example of a bar code is shown in Fig. 3. One-dimensional code A is the Japanese Patent Publication No. 8-210504, Japanese Patent Publication No. 8-16991 , Tokuho 8—1619 16 “Identification code” is applied.

In the two-dimensional code A, an auxiliary area 12 is formed around the data area 11 where the binary mark K of HL is matrix-arranged, and the data area 11 and the auxiliary area are formed. The rear 12 is surrounded by an X-axis baseline 14, a Y-axis baseline 13, and a corner mark 15 to form unit data. By increasing the number of unit divisions 16 for recording the binary mark K for the data area 11, the information amount of the data area 11 can be increased exponentially. Since the amount of information is large, single or decimal unit data can be specified as the amount of information equal to or more than the number of issued cards of all cards.

Further, it is easy to convert the encrypted data using the auxiliary area, such as recording the encrypted data on the arrangement selection of the unit area of the data area in the auxiliary area 12.

In the case where a plurality of unit data of the two-dimensional code A is used or when additional printing is performed each time the pre-card 1 is used, as shown in FIG. 4, the unit data of the two-dimensional code A is used. Adjacent to (addition to) the auxiliary area 12 of the data, the baseline 13 of the unit data of the two-dimensional code A is overprinted to form the overlap area Q and reuse the used card. (It is difficult to completely erase the additional printing, leaving the auxiliary area 12 for the initial printing.) Next, a description will be given of the recording of the security individual information 2 in which the accidental change data formed by the printing record including the contingent element is included.

The two-dimensional code A is different from the conventional one-dimensional code such as a bar code in that the HL binary mark is arranged in a matrix. The information printed on the card 1 includes information such as the printing position of the two-dimensional code, the printing angle, the density distribution of each data between the two-dimensional codes, the position of the data, and the profile. By changing, the incidental element is inherent, ,,

As a means for accidentally changing the printing position, printing angle of the two-dimensional code, the density distribution of each data between the two-dimensional codes, the data position, the shape, and the like, the above two-dimensional code is used. In printing a printer A on a securities card (printed card) 1, the securities and the print head of the printer are vibrated relative to the lower right, left, right and left. upset causes _π when this becomes mechanically vibrate, vibration period between this upsetting, the oscillation width, the relative positions and the like and endogenous child an accidental change data changes randomly (irregularly) and. In printing on a printer, the securities (prepared card) 1 can be vibrated and shaken up, down, left and right, and back and forth, so that both can be relatively shaken and shaken. When printing the printer using the dot printer and the ink jet printer, the printer head vibrates, The object of the present invention can also be achieved by agitation.

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 of the data, the shape, etc. When reading the two-dimensional code の in Fig. 3, the density distribution of each data between the two-dimensional code, the printing position, the printing angle, and the two-dimensional code are read. Of the unit area of the data area 11 and the darkness The unit data is detected by correcting the unit data and the function of recording the corrected parameters in the auxiliary area 12 is used. The correction parameters recorded in the data can be applied as accidental change data.

The first invention of the present application is to discover counterfeit securities by detecting the above-mentioned accidental change data of individual securities (prepared card) 1. (Prepare code) Securities individual information 2 (for example, security serial number) for 1

By recording accidental change data (corrected unit data or one of the correction parameters recorded in the auxiliary area 12) with respect to the information of the securities, In the discrimination, the individual security information of each security and the accidental change data of each security can be compared with the computer of the management center.

If the accidental change data is not recorded on the computer of the management center, the security individual information (for example, security serial number) 2 and the incidental change data inherent in determining the authenticity of the securities are used. By entering the data into a retailer or by entering into a fixed area, a computer that manages a certain chain range, the individual security information (for example, security serial number) 2 and the incidental The existence of a security (prepared card) 1 with the same change data (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 individual securities information 2 is recorded and displayed on the securities paper in the securities (prepaid card) 1 in Fig. 1 (for example, the accidental change data shown in Fig. 4). Incorporate 2D code A ')

As the accidental change data 4, in the two-dimensional code A ′ in FIG. 4, the corrected unit data or the corrected two-dimensional data having the corrected parameters recorded in the auxiliary area 12 are used. It can be a code.

In recording the accidental change data 4, the accidental change data is printed and recorded in the same manner as the underlying securities individual information 2. That is, magnetically readable two-dimensional code printing record, optically readable 2D code printing record In this case, the accidental change data (printing with the corrected 2D code) 4 is used instead of the normal general printing ink as printing with the invisible ink. The content can be unclear. In addition, similarly to the printing area 3 of the individual securities information 2, the printing area 5 of the accidental change data 4 is set, and the printing area 5 is printed with an ink absorbing a specific color wavelength. Or by printing the ground color with a black ink, and printing the individual security information 2 with an ink that emits light at a specific color wavelength (for example, a black infrared light emitting ink), so that the accidental change data 4 is printed. It can be recorded in a masked state according to YA5.

In carrying out the second invention of the present application, the securities (prepared card) 1 on which the accidental change data 4 is recorded and displayed are used, and the securities (prepared card) 1 are used to determine the authenticity of the securities. By comparing the underlying accidental change data with the accidental change data 4 recorded and displayed on the securities, the counterfeit discrimination of the accidental change data of both is used to find counterfeit securities.

The first and third inventions of the present application convert individual two-dimensional codes into securities and form individual security information in which accidental change data is embedded by printing and recording contingent elements. And individually characterize securities to quickly detect the presence of copied securities and minimize the damage caused by counterfeit securities Also, by making accidental change data inherent, making counterfeit securities impossible to produce in a cost-effective manner (offset printing requires a large number of sheets in a cost-effective manner) ( .

The second invention and the fourth invention of the present application are directed to collating accidental change data information on securities with accidental change data inherent in individual securities information, and finding a counterfeit security by a mismatch between the two. It is possible to detect counterfeit securities without the need for a management center or other such computer. Industrial applicability

As described above, the present invention is used as a measure to prevent the unauthorized use of depreciated securities that have been used by multiple uses, such as gift certificates, tickets, and pre-paid cards for providing goods and services. It has particular utility when applied.
