Description

  The present invention relates to an authenticity determination body for determining authenticity of an article, an authenticity determination article, and an authenticity determination method thereof.

  Conventionally, as a measure for preventing counterfeit goods, pirated goods, etc., hologram labels that are difficult to counterfeit have been attached to articles.

However, the hologram label has been recognized to have a high effect so far, but the hologram itself may be forged by the recent forgery technology.
In addition, there is a risk that the hologram label may be peeled off from the used article and used illegally. It was.

  On the other hand, a system such as traceability management using a bar code label to clarify processes such as manufacturing and distribution has been proposed (for example, Patent Document 1), and application to the forgery prevention field has also been proposed.

  However, since such a system requires the scanned barcode data to be checked against the host server data, an online environment is required. If it is not in place (for example, there are a large number of offline environments in the distribution of branded products), setting up a new online environment has been a heavy burden on the introduction.

Moreover, since it is possible to read a simple barcode with a scanner and punch it out with a printer, it is possible to immediately create a fake, and there is an unsafe aspect regarding security.

  The invention of claim 8 is the authenticity determination method of the authenticity determination article for determining the authenticity determination article according to claim 7, wherein the first code (11) is read and the second code (13) is read. The authenticity determination method of the authenticity determination article is characterized in that authentication is performed by reading and comparing and comparing the two.

  According to the present invention, since each code is machine-readable, even if it is a counterfeit product that is very similar to a genuine product, its authenticity can be accurately and easily determined.

  In addition, since the first code and the second code are associated with each other and the second code is formed using the security member, forgery is difficult and high security can be ensured.

  Furthermore, by using a one-dimensional code for the first code, the current infrastructure can be utilized, and the load on introduction can be reduced.

  Furthermore, by using a two-dimensional code for the second code, the information amount is equal to or greater than that of the one-dimensional code, but the size can be made smaller, and the amount of security member used can be minimized. Increase in cost can be suppressed.

  On the other hand, since the authenticity determination is performed by reading the first code, reading the second code, and comparing and collating them, the authenticity determination can be performed on the spot even in an offline environment.

  The present invention makes it possible to accurately and easily determine the authenticity of a counterfeit product that is very similar to a genuine product while utilizing the current infrastructure, and has a high security against counterfeiting and alteration. The object of providing an authenticity determination article and its authenticity determination method is realized by providing an article with a one-dimensional code and a two-dimensional code that is associated with the one-dimensional code and is formed using a security member. To do.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a diagram showing an embodiment of an authenticity determination article according to the present invention.
The authenticity determination article 10 of the present embodiment is an article, casing, package, or the like placed in the distribution process, and includes a one-dimensional code (one-dimensional barcode) 11 and an authenticity determination body 12.

  The one-dimensional code 11 indicates the type information of an article and is a first code that can be read by a machine 20 by a reading device 20 such as a bar code reader. Has been.

  In general, since many articles are often provided with a one-dimensional code in order to use a POS system or the like, the one-dimensional code 11 may use an existing barcode. Further, it may be a unique serial number (individual information) that is expected to increase in use in the future.

  The authenticity determination body 12 is for determining the authenticity of the authenticity determination article 10 and includes a two-dimensional code (two-dimensional barcode) 13.

The two-dimensional code 13 is a second code that is associated with the one-dimensional code 11, is formed using a security member, and is machine-readable.
For example, (1) the data of the one-dimensional code 11 is included in the two-dimensional code 13 as it is. (2) information that is uniquely determined from the data of the one-dimensional code 11 by a predetermined operation or encryption. Is included in the data of the two-dimensional code 13.

  Here, the security member is a member that has security properties and is difficult to counterfeit. The security member includes a light diffraction layer (light diffraction structure) that causes light interference and optical anisotropy. A liquid crystal layer, a color change layer whose color changes under a predetermined condition, or the like can be used.

  In the case of the optical diffraction layer, a hologram on which a hologram image is recorded, a diffraction grating that causes light interference, or the like can be used. For example, in the case of a hologram, (1) a barcode is printed on the hologram seal; (2) Patterning the metal reflection layer of the hologram into a barcode shape, or recording the barcode reproducibly with a predetermined light if it is a diffraction grating.

  In the case of a liquid crystal layer, for example, (1) a cholesteric liquid crystal having a color variable effect and polarization is applied in a barcode, (2) a cholesteric liquid crystal is uniformly applied or a cholesteric liquid crystal film is applied, and a laser is applied. Partially denatured to change the alignment state and pattern it into a bar code shape. (3) A cholesteric liquid crystal is uniformly applied or a cholesteric liquid crystal film is pasted on it, and a bar that changes the polarization state of light Examples of the method include laminating a code-like retardation layer.

  In the case of the color change layer, for example, a method of applying a special ink such as an ultraviolet fluorescent ink, an infrared fluorescent ink, an infrared absorbing ink, or an infrared light emitting ink in a barcode shape.

The reading device 20 is for reading the one-dimensional code 11 and the two-dimensional code 13, and includes a display unit 21 for displaying the read barcode data.
The reading device 20 may be either a common reading device or a dedicated reading device. In particular, the reading of the two-dimensional code 13 is, for example, a hologram, by reversing the reflection mode of the reading device 20. For example, it is preferable that the characteristics of the security member are utilized.

Next, the authenticity determination method of the authenticity determination article 10 according to the present embodiment will be described with reference to FIGS. 1 and 2.
FIG. 2 is a flowchart showing the authenticity determination method of the authenticity determination article 10.
First, the one-dimensional code 11 is read by the reading device 20, and the data of the one-dimensional code 11 is displayed on the display unit 21 of the reading device 20 (S101).

  Next, similarly to the one-dimensional code 11, the two-dimensional code 13 is read and the data of the two-dimensional code 13 is displayed (S102).

Then, the worker compares and verifies the data of both displayed barcodes (S103), and determines whether the data match (S104).
If the data match, it is determined to be a genuine product (S105), and if the data does not match, it is determined to be a counterfeit product (S106).

Thus, according to the present embodiment, the following effects are obtained.
(1) Since the one-dimensional code 11 and the two-dimensional code 13 are compared and collated on the spot, it is possible to determine the authenticity without performing data collation with respect to the host server. Cost can be reduced.

(2) Since the two-dimensional code 13 is associated with the one-dimensional code 11 and is formed by using a security member, it is difficult to forge, and since it is mechanically processed by the reader 20, the real thing Compared with the conventional method for visually determining the authenticity, the authenticity can be determined easily and reliably.

(3) Since the small-sized two-dimensional code 13 is used while the amount of information is equal to or greater than that of the one-dimensional code, the amount of use of security members can be minimized, and an increase in cost can be suppressed.

(4) By using the one-dimensional code used in the distribution process as it is, the current infrastructure can be utilized, and no change in equipment is required.

(5) When using ink for a liquid crystal layer or a color change layer, it is only necessary to print a barcode on a general-purpose member (paper, film, etc.) and affix it to an article. it can.

(6) Since it is possible to prevent the distribution of counterfeit and pirated goods such as branded products, genuine products, and industrial products, and falsification of information during the distribution process, the authenticity determination product 10 can be used for agricultural products, livestock products, It can be suitably used for traceability management of industrial products, postage systems, product replenishment ordering systems, warehousing and unloading management systems, manufacturing process management systems, and the like, and the reliability of articles is also improved.

(Modification)
The present invention is not limited to the embodiments described above, and various modifications and changes are possible, and these are also within the equivalent scope of the present invention.
(1) The example in which the barcode data is displayed on the display unit 21 for comparison and verification has been described, but in the case of the reading device 20 that does not include the display unit 21, the reading device 20 is connected to a terminal such as a personal computer. Data may be displayed by connection, or the connected terminal may be subjected to data comparison and collation. In this way, human error can be eliminated and the accuracy of authenticity determination is further increased.
(2) Although the example of the offline environment has been described, when the online environment is prepared, the security level may be gradually increased by using a matching process for the host server.

(3) Security may be improved by stacking or combining three security members (light diffraction layer, liquid crystal layer, color change layer).
(4) Since the two-dimensional code 13 only needs to contain at least information that can be compared with the one-dimensional code 11, other information may be added.
(5) The first code may be a two-dimensional code, and the second code may be a one-dimensional code.

It is a figure which shows the Example of the authentication article | item by this invention. 5 is a flowchart showing a method for determining the authenticity of the authenticity determination article 10
