Description

  The present invention relates to a product authenticity determination method and system capable of determining whether or not a product is a regular product by using a barcode attached to the product.

  For various products, for example, bottled beverages, prizes may be provided to buyers by lottery for the purpose of sales promotion. In this case, an access code is attached to the bottle surface in the form of a two-dimensional barcode such as a QR code covered with a crimping seal, and the purchaser is peeled off to access the Internet site using the access code. And registering them to provide premiums.

  Here, there is a risk of illegal activities such as purchasing a legitimate product with a barcode attached, illegally copying the barcode attached to it, attaching it to a counterfeit product, and distributing it to the market. is there. Such counterfeits cannot be found at a point before being sold in a retail store or the like. A buyer who has purchased counterfeit goods can understand it only after opening the barcode and accessing the Internet site. In other words, fraud cannot be found without opening the barcode.

  In view of these points, an object of the present invention is to make it possible to confirm whether or not a product is genuine without opening the barcode attached to the product, and to illegally copy the barcode. The object is to propose a method and system for determining the authenticity of a product that can prevent the harmful effects of the product.

In order to solve the above problem, a method for determining the authenticity of a product using the barcode pair of the present invention is as follows:
Bar code information encoded in a bar code pair consisting of a visible unopened confirmation bar code and an open registration bar code that is sealed in an openable state is provided with the bar code pair Create a database registered in the form associated with
When the reading information of the barcode attached to the product is provided, it is determined whether the reading information is the opening registration barcode or the unopened confirmation barcode.
In the case of the opening registration barcode, the attribute of the opening registration barcode information registered in the database is updated from unopened to opened,
In the case of the unopened confirmation barcode, check the attribute of the unregistered barcode information paired with the unopened confirmation barcode information registered in the database,
If the attribute is unopened, the product with the unopened confirmation barcode is determined to be a regular product,
When the attribute is already opened, the product is determined to be a counterfeit product.

  In the present invention, a pair of barcodes is attached to the product, one is in a visible state (open state), and the other is in a sealed state (secret state). In a retail store or the like, by reading a visible unopened confirmation barcode and comparing the information with the registered contents of the database, it is possible to confirm whether or not the product attached with the barcode has already been opened. In other words, it can be confirmed whether or not the product has already been sold and the registration barcode in the sealed state (secret state) has been opened and the registration procedure has been performed. If the product has already been opened, it can be determined that the product is a counterfeit product and the attached barcode has been illegally copied, and can be excluded before being purchased by a general consumer.

  Here, as the opening registration barcode and the unopened confirmation barcode, a two-dimensional barcode such as a QR code having a large information storage capacity can be used.

  In addition, when centrally managing the product at one place or multiple places, the barcode reading information given to the product should be provided from a retail store or the like via a communication network such as the Internet. do it.

  In this case, the determination result as to whether or not the product is a regular product may be notified to a retail store or the like that provides the barcode reading information via a communication network such as the Internet. Good.

  Furthermore, in order to facilitate registration that the unsealing registration barcode attached to the product has been opened, a free gift or the like is provided to the registration procedure, or if the registration procedure is performed, a lottery or A service such as providing a present by performing a lottery may be performed.

  Next, the present invention is a product authenticity determination program using a bar code pair, characterized by causing a computer to execute the above method.

On the other hand, a product authenticity determination system using the barcode pair of the present invention is:
A barcode pair consisting of an open registration barcode that is sealed in an openable state and a visible unopened confirmation barcode for attachment to a product,
The barcode information encoded in the barcode pair, and a database registered in a form in which the product to which the barcode pair is assigned is associated;
Based on the registration contents of the database, a true / false determination server for determining the authenticity of the product,
A communication terminal capable of transmitting and receiving information to and from the authenticity determination server via a communication network such as the Internet;
A barcode reader built in or connected to the communication terminal;
The authenticity determination server is:
When receiving the barcode reading information attached to the product, a barcode determination unit for determining whether the reading information is the opening registration barcode or the unopened confirmation barcode;
When the read information is the opening registration barcode, an update unit that updates the opening registration barcode attribute registered in the database from unopened to opened,
When the read information is the unopened confirmation barcode, the attribute of the unregistered barcode that is paired with the unopened confirmation barcode registered in the database is checked, and the attribute is If unopened, the product with the unopened confirmation barcode is determined to be a regular product, and if the attribute has been opened, the product is determined to be a counterfeit. And a product discrimination unit.

  Here, as the registration barcode and the opening confirmation barcode, a two-dimensional barcode such as a QR code can be used.

  In addition, the registration barcode can be attached to the product in a state of being sealed by a peelable seal that cannot be reattached.

Furthermore, the bar code pair can be attached to the product in any of the following forms (1) to (3).
(1) A form in which the barcode pair is directly attached to the product
(2) A form in which the barcode pair is attached to a packaging such as a product packaging box
(3) A form in which one barcode is directly attached to the product and the other barcode is attached to the product packaging

  In addition, upon receipt of the reading information of the opening registration barcode, the authenticity determination server transmits to the communication terminal that a predetermined prize is provided or is determined in advance. It can be set as the structure provided with the notification part which transmits the process result obtained by performing processes, such as the lottery which has been carried out.

  Next, the present invention relates to a barcode pair attached to a product used in the above-described method for determining the authenticity of the product, and the unopened confirmation barcode that is visible and the unsealed seal that is openable A bar code for registration, and the unread confirmation barcode is encoded with a character string for ID, information indicating confirmation communication, and information indicating a communication destination. The bar code is encoded with an ID character string, information indicating registration communication, and information indicating a communication destination.

  Further, the present invention is a product attached with a barcode pair used in the method for determining authenticity of the product, wherein the barcode pair is in a visible unopened confirmation barcode and in an openable state. A bar code for opening registration that is sealed, and the bar code for unopening confirmation is encoded with an ID character string, information indicating that the communication is for confirmation, and information indicating a communication destination The opening registration bar code is encoded with an ID character string, information indicating registration communication, and information indicating a communication destination.

  Even in this case, the barcode pair may be attached to the product in any one of the above-described forms (1) to (3).

  In the authenticity determination method and system for a product using the barcode pair of the present invention, an unopened confirmation barcode is attached to the product in a visible state, and an opening registration barcode is attached in a sealed state. The correspondence between the code pair and the product is registered in the database in advance, and when the reading information of the bar code for opening registration is received, the attribute information of the product to which it is attached is changed from unopened to opened and registered in the database When the reading information of the unopened confirmation barcode is received, it is determined that the product is a legitimate product if the attribute of the product to which it is attached is unopened, and if the product has been opened The product is determined to be a counterfeit.

  Therefore, according to the present invention, it is possible to confirm whether or not the illegally copied barcode pair is a product (imitation product) without opening the opening registration barcode. Therefore, it is possible to prevent the counterfeit product from being sold in the hands of consumers in advance.

  In the following, an embodiment of a product authenticity determination method using a barcode pair to which the present invention is applied will be described with reference to the drawings.

[Principle of product authenticity]
First, with reference to FIG. 1, the principle of the authenticity determination method for goods according to the present invention will be described. The system according to the present invention can be constructed using the Internet and communication technology, two-dimensional or one-dimensional barcode technology, and server technology. A pair of two-dimensional or one-dimensional barcode 2 consisting of a visible unopened confirmation barcode 2a and a shielded opened registration barcode 2b is attached to the product 1 to be sold. Generally, a barcode label 3 on which barcodes 2a and 2b are printed is affixed to the product 1, and a portion of the barcode label 3 on which the registration barcode 2b is printed is peelable, and A cover seal that cannot be reattached, for example, a pressure-bonding seal 4 is attached, and the registration barcode 2b is sealed.

  Each unopened confirmation barcode 2a and unregistered barcode 2b are encoded with a unique ID character string, and the barcode information including the combination of the character strings is stored in the authenticity determination server 5 when the character string is issued. Are registered in the database 6. In addition, a label indicating unopened is attached to the combination of the character strings.

  The product 1 to which the barcode pair 2 is attached is shipped from the product manufacturer 7 to the store 8. In the store 8, the visible unopened confirmation barcode 2 a is read by a barcode reader attached to the POS system or the like, and the read information is sent to the authenticity determination server 5 via a communication network such as the Internet. Send. The authenticity determination server 5 searches the database 6 for a character string pair that includes the character string represented by the received unopened confirmation barcode 2a, and the index assigned to the character string pair is “unread” Check if it is "opened" or "opened". In the initial state, it is unopened. After confirming this, the authenticity determination server 5 determines that the product is a legitimate product, and transmits that fact to the store 8.

  The purchaser 9 who has purchased the product 1 at the store 8 peels off the pressure-sensitive seal 4 and opens the opening registration barcode 2b, and reads the contents of the opening registration barcode 2b into a mobile phone reading system or a barcode attached to the personal computer. The data is read by a reader and transmitted to the authenticity determination server 5 via a communication network such as the Internet. When the authenticity determination server 5 receives the information of the opening registration barcode 2b, the index assigned to the character string pair including the character string attached thereto is updated from “unopened” to “opened”. To do. Thereby, the unsealing registration procedure for the product is completed.

  As described above, the retail store / general consumer / manufacturer / distributor sends the unopened confirmation barcode 2a to the server 5 and searches the database 6 to determine whether the product is “opened” or “unopened”. Can be confirmed. The confirmation result of the unopened confirmation barcode 2a after the opening registration is “opened”, so that the unopened confirmation code 2a is the same and the unopened barcode 2b is received. In this case, it can be determined that the product is a counterfeit product.

  For example, as shown in FIG. 1, a pair of character strings encoded in a barcode pair 3 attached to a regular product 1 (1), 1 (2), 1 (3)... (A100 / a100), (A101 / a101), (A102 / a102)... And the fake manufacturer 10 purchases one genuine product 1 (1) and copies an unauthorized copy of the barcode pair 3 attached thereto. Assume that a large number of counterfeit products 1A are manufactured and distributed in the market. In this case, the first one of the products with the same barcode pair 3 attached can be opened and registered, but after that, the products with the same barcode pair 3 attached are fake Can be excluded.

  Thus, in the present invention, the relationship between the public key and the secret key is formed by sealing and shielding one of the barcode pairs for authenticity determination based on the networking technology and the automatic barcode recognition technology. . This prevents unauthorized opening registration due to mischief that occurs when a single barcode is used for opening confirmation and opening registration, and without opening the sealed registration barcode (secret key). The authenticity of the product can be judged. Furthermore, it is a simple and reliable fully automatic function that can determine authenticity from anywhere as long as it can use a communication network such as the Internet without being restricted by a specific network, a device environment such as an IP address and a terminal device ID. A counterfeit product discrimination system can be constructed.

[Product authenticity determination system]
Next, with reference to FIGS. 2 to 4, an embodiment of a product authenticity determination system to which the present invention is applied will be described. FIG. 2 is a schematic configuration diagram showing the overall configuration of the product authenticity determination system, and FIGS. 3 and 4 are schematic flowcharts showing the operation of the authenticity determination system.

(overall structure)
First, referring to FIG. 2, the product authenticity determination system 11 includes a management device 12 including a authenticity determination server 12a and a database 12b, and a QR code (barcode) reader installed in each store. It has a POS terminal 14 to which the device 13 is attached and a communication terminal 16 such as a mobile phone 15 with a built-in QR code reader owned by the product purchaser, and the Internet between the communication terminal 16 and the management device 12 17, communication is possible via a communication network including a mobile phone network 18 and the like. Further, a bar code pair 20 attached to a product 19 such as liquor is provided. The bar code pair 20 includes an unopened QR code 20a and an open registration QR code 20b printed on the surface of the bar code label 21, and the open registration QR code 20b is peelable and cannot be attached again. Sealed by a seal 22.

  Here, the procedure for opening and registering the barcode attached to the product 19 is performed as follows. The pressure seal 22 hiding the QR code 20b for opening registration is peeled off from the bar code label 21 attached to the product 19, and the information carried on the QR code 20b for opening registration is read by the communication terminal 16, and the Internet 17 to the management apparatus 12 via a communication network such as 17. The management apparatus 12 searches the database 12b with the received information, and records a label indicating that the package is opened in the corresponding record of the database 12b and the date and time.

  The procedure for confirming the opening of the bar code attached to the product 19 is performed as follows. The visible opening registration QR code 20a printed on the barcode label 21 attached to the product 19 is read by the communication terminal 16, and the information carried in the read unopened confirmation QR code 20a is stored on the Internet. 17 to the management apparatus 12 via 17 or the like. The management apparatus 12 searches the database 12b with the received information, and displays the opening date and time when the corresponding record in the database 12b is opened or unopened and the opening date and time when the record is opened on the screen of the communication terminal 16 via the Internet 17. , Display with unopened or unopened explanatory characters.

  Next, the QR codes 20a and 20b are matrix-type two-dimensional barcodes, and the barcode label 21 attached to the product 19 has two QR codes 20a for unopening confirmation and QR codes 20b for opening registration. It is printed. A management device connected to each of these QR codes 20a and 20b via a unique ID character string generated by random numbers, a type of confirmation communication or registration communication, and the Internet 17 Twelve communication destination information, for example, URL information, is carried in a format that can be transmitted from the communication terminal 16 to the management device 12.

  The QR code reader that is connected to or built in the communication terminal 16 can use a QR code reader that is currently popular. For example, the QR code reader device 13 includes an optical reading unit 13a and a reading switch 13b, and the reading unit 13a outputs a display by a laser beam indicating a readable position. By aligning the display with the QR code 20a, 20b and pressing the read switch 13b, the QR code 20a or 20b is automatically read, and the content carried in the QR code 20a or 20b is decoded into a character string. Thus, the input is transferred as an input equivalent to the keyboard input of the POS terminal 14 connected by the USB terminal.

  The POS terminal 14 recognizes the data input from the QR code reader device 13 as input from the keyboard, and immediately uses the communication destination information obtained from the QR code 20a or 20b to check the unique ID character string. With the identification information of the communication for communication or the communication for registration, it connects to the management apparatus 12 via the Internet 17 or the like, and transmits the character string and the identification information for the confirmation communication or registration communication.

  On the management device 12 side, a determination result is generated for unopened confirmation, and a registration success / failure is generated for open registration, for example, HTML format data is transmitted to the POS terminal 14, and the POS terminal 14 displays It is displayed via a web browser installed in the device 14a.

  As the communication terminal 16, a mobile phone 15 with a built-in QR code reader that is currently in widespread use can be used. For example, the mobile phone 15 includes a camera 15a and an operation unit 15b that are also used as an optical reading unit. The content captured by the camera is monitored on the screen 15c of the operation unit 15b, and the QR code 20a, 20b is automatically read by pressing the operation unit reading switch with the monitor display aligned with the QR code 20a or 20b. Then, the content carried by them is decoded into a character string. Then, using the communication destination information obtained from the QR codes 20a and 20b, the Internet 17 is transmitted from the mobile phone wireless communication network 18 with the unique ID character string and the identification information for confirmation or registration. It connects to the management device 12 via, and transmits a character string and identification information for confirmation communication or registration communication.

  On the management device 12 side, a determination result is generated for confirmation, a registration success / failure is generated for registration, and data in the HTML format or a similar format is transmitted to the mobile phone 15. The information is displayed on the display device 15c via a built-in browser.

  In the database 12b of the management apparatus 12, when a large number of QR codes 20a and 20b are issued, a pair of unique ID character strings carried on the QR codes 20a and 20b printed on the respective barcode labels 21 is provided. Is registered. In addition, as attribute information, an index indicating whether it is already opened or not opened, and information about the date and time when it is already opened are given.

(Description of operation)
Next, with reference to FIG. 3 and 4, operation | movement of the authenticity determination system 11 of the goods of this example is demonstrated. First, the processing on the communication terminal 16 side that is the QR code reading side is as follows.

The check program is as follows, as shown in the flowchart of FIG. First, a check program is activated in SubST1. Next, the unique ID character string carried in the unopened confirmation QR code 20a in SubST2 is queried from the database 12b. Thereafter, in SubST3, it is determined whether or not “opened” is registered in the row data corresponding to the unique ID character string. Next, when there is no registration of “opened” in SubST4, it is determined that the product is genuine. In addition, when there is a registration of “opened” in SubST5, it is determined that the product has been opened, and if the product is not peeled off from the crimp seal 22 of the QR code 20b, the product has already been opened even though it is an unopened product. So add to the conclusion that it is fake.
ST11:

As shown in FIG. 4, this present program operates in SubST 6, a predetermined program such as a lottery is executed, and the result is added to transmission data to the POS terminal 14 or the mobile phone 15.
ST17:
The result evaluation program formats the status of the registration result (the execution result of ST15) and the display of the lottery result (the execution result of ST16), and transmits the result to the POS terminal 14 or the mobile phone 15 from the result transmission program (ST12).
ST13:
When the predetermined communication is completed, the communication is disconnected.

(Operational effects of the embodiment)
Thus, in the authenticity identification system 11 of the product of this example, the communication terminal 16 transmits the read information to the authenticity determination server 12a according to the communication destination information carried in the QR code 20a or 20b, and When the authenticity determination server 12a receives the information carried in the QR code 20a or 20b (ST8), one of the opening confirmation program or the opening registration program is activated using the identification information for confirmation or registration. (ST9, 14).

  The opening confirmation program is searched by the check program (ST10) for searching the database 12b, executes the corresponding result evaluation program (ST11), starts the result transmission program (ST12), and transmits it to the communication terminal 16.

  The opening registration program searches the database 12b and confirms whether or not the row data including the unique ID character string has been registered by the registration program (ST15). , Update the row data. The present program (ST16) is a present program for carrying out a lottery or lottery for motivating the user to perform the registration work. The result evaluation program (ST17) displays the status of the registration result (execution result of ST15) and the lottery result. After shaping (execution result of ST16), the result transmission program (ST12) transmits it to the communication terminal 16.

  Therefore, if the system 11 of this example is used, a QR code for unopened confirmation that functions as a public key attached to the product using a POS terminal installed in the store where the product is sold, etc. 20a is read and transmitted to the authenticity determination server 12a to confirm whether the product is unopened or opened. When the unsealed result is received and the unsealing QR code 20b of the product is in an unopened state, it can be determined that the product is fake. That is, it can be seen that the copy is a counterfeit product with an illegally copied QR code pair attached. Therefore, it is possible to prevent such counterfeit products from flowing into the market or being sold to customers.

Therefore, using the system 11 of this example has the following advantages.
(1) By using the QR code, it is possible to confirm whether or not the product is an illegally copied product by a simple operation by the customer himself / herself.
(2) By attaching two single types of product management IDs in the form of QR codes to each product, authenticity can be determined for each product.
(3) Since the presence of a fake can be specified by a simple method, it is possible to suppress or prevent the fake from being distributed to the market.
(4) Since the QR code for opening registration is sealed with a seal such as a crimping method that cannot be re-adhered, tampering with unauthorized opening can be eliminated.
(5) Since the QR code, which is the product management ID, can be centrally managed by the web server (authentication determination server), the authenticity of the product can be checked not only from within Japan but also from overseas.
(6) Since customers are motivated by applying for gifts, lotteries, and lotteries, customers register for opening without realizing it. For this reason, a high opening registration rate can be expected without trouble.

[Other embodiments]
In the above embodiment, a QR code is used as the bar code. Two-dimensional barcodes other than QR codes can also be used. It is also possible to use a one-dimensional barcode.

  In the above embodiment, the QR code is directly attached to the product, but it may be attached to a product packaging box or the like. Of course, one barcode may be directly attached to the product, and the other barcode may be attached to a packaging box or the like.

  Furthermore, in the above embodiment, a pair of barcodes are printed side by side on the surface of the barcode label. However, an unregistered barcode is printed on the surface of the barcode label. It can also be set as the structure covered with the crimping seal etc. which are printed on the surface.

  Further, in order to enhance the security of the system using the unopened confirmation barcode and the unregistered bird code, for example, the validity of these barcodes is authenticated by a public key and a private key using RSA technology. What should I do? In this case, in generating the ID encoded in the barcode, first, the original ID character string is created, and based on this, the encrypted character string is created using the two keys by RSA, These character strings are used as IDs for encoding into barcodes. Here, the ID character string before encryption and the ID character string after encryption are disclosed without disclosing the key. When determining the barcode, in order to determine whether or not the ID encoded in the barcode is legitimate, after reading a series of ID strings from the barcode, the ID string is transferred to the authentication server. From the ID character string, the ID character string used as the source for generating the ID is extracted, and the result obtained by encrypting it with the key is the encrypted ID character string in the ID character string read from the barcode. To determine whether or not. If they do not match, it is determined that the ID is invalid.
