Description

System and method for commodity anti-counterfeiting identification

technical field

The invention relates to the communication field, in particular to a product anti-counterfeiting identification system and method.

Background technique

For a long time, counterfeit and shoddy goods have not only seriously affected the economic development of the country, but also endangered the vital interests of enterprises and consumers. In order to protect the interests of enterprises and consumers and ensure the healthy development of the socialist market economy, the country and enterprises spend a lot of manpower and financial resources on anti-counterfeiting and anti-counterfeiting every year.

The digital anti-counterfeiting technology already available, such as RFID label anti-counterfeiting technology, pastes RFID labels with different serial numbers on the commodity packaging, and stores the serial numbers in the merchant's computer in the form of a database. When the RFID card reading device at the shopping point is connected for identification, the RFID card reading device will return the read tag serial number to the merchant database through the network, and the merchant's computer will return the identification information and identification results to the user's hands, so as to obtain the authenticity of the product. Pseudo and additional information on merchandise. But this anti-counterfeiting method has the following problems: 1. The insecurity of commodity information, as long as anyone has a card reading device, he can read commodity information at will, add or rewrite commodity information. 2. Device loopholes, false display devices For fake products, due to the openness of product information, it is very easy to read the serial number of the real product with a reader, and then store the obtained serial number in the card reader (a handheld The reader can store 1 million serial numbers), when reading fake goods, the real serial number stored in the card reader is randomly displayed, so that only the real serial number can be found on the background server through the network or telephone Fake product information. 3. Network loopholes, fake system for fake products, forge a set of code anti-counterfeiting call-in system, network virtual call-in service number, only need thousands of yuan, read out the serial number of fake products, through the virtual number, transfer to fake In the service background of the system, when the product query password and product information are input, what is obtained is false information about the product. 4. It does not meet the consumer's requirement to be able to immediately identify the authenticity of the product. From the actual use of the anti-counterfeiting system of the scratch code card, few people use the telephone to enter the number or use the Internet to check the authenticity of the product.

The commodity anti-counterfeiting identification method of the commodity anti-counterfeiting identification system of the present invention:

It includes a commodity identifier and an RFID tag placed in the commodity. The commodity identifier is provided with a product information database. The commodity identifier reads the commodity ID number of the RFID tag in the commodity and inquires whether the commodity ID exists in the product information database. If the product information record corresponding to the product number does not exist, it means that the product ID number of the product does not belong to the identification network, and the product identifier stops the identification; if it exists, the product identifier generates the first verification code through the encryption algorithm of the product ID number , compared with the second verification code in the RFID tag, if the first verification code does not match the second verification code, the commodity identifier stops identifying; if the first verification code matches the second verification code, the commodity identifier reads The product information encrypted in the RFID tag is obtained for decryption.

The commodity information encrypted in the RFID tag includes one or more of the following: commodity origin, commodity designated sales area, commodity model information, commodity production date information and commodity quality grade.

The device and method of the present invention have the following advantages:

1. The RFID tag of each product has a unique product ID number, which cannot be modified or copied. The authenticity of the product can be effectively identified through the identification system.

2. The commodity information is encrypted and stored in the RFID tag of the commodity. Only when the commodity authenticator and the commodity mutually authenticate successfully can the commodity authenticator read the commodity information in the RFID tag, and the commodity information must be decrypted before it can be displayed. The security of the product information is very good; in addition, because the second verification code corresponding to each product and the key of the first verification code of the product authenticator are generated by an encryption algorithm based on the product ID number, each The key corresponding to a product will be completely different. For those who want to copy the electronic label of the product by cracking the product password, it is meaningless to crack the key of the verification code.

3. Every product of the merchant is registered with an "identity code". When the company ships to the dealer, the RFID tag records the information of the region where the product is sold. When the product identifier shows the sales place and the consumer's purchase location If it does not match, consumers can defend their rights to the product company based on this, which can effectively prevent commodity fleeing.

4. The product identifier is equipped with a supervision card, which can identify the authenticity of the product identifier, effectively avoiding fake equipment from counterfeit products.

5. Simplified operation, real-time inspection and window-based display.

Commodity authenticator 2 is issued by the management unit, and sent to the read-write unit after being processed by the cryptographic algorithm unit. The read-write unit performs command data exchange on the RFID tag 1 of the commodity, and displays the identification result through the display unit; the internal data of the management unit Data update via wireless communication unit.

Product identifier 2 is provided with a product information database. When commodity identifier 2 reads the commodity ID number of RFID tag 1 in the commodity, it inquires whether there is a product information record corresponding to the commodity ID number in the product information database. If it does not exist, it means The commodity ID number of this commodity does not belong to this authentication network, and then commodity authenticator 2 stops distinguishing, and if exists, commodity authenticator 2 will generate the first verification code by encryption algorithm, and the second verification code stored in the RFID tag 1 in advance by the businessman. Codes are compared, and both the first verification code and the second verification code use the A3 encryption algorithm, if the first verification code does not match the second verification code, the commodity authenticator 2 stops the identification; if the first verification code and the second verification code If the codes match, the commodity authenticator reads the encrypted commodity information in the RFID tag and decrypts it. If the decryption is unsuccessful, the commodity authenticator stops the authentication. If the decryption is successful, the commodity authenticator displays the commodity information.

Also comprise supervisory card 3, the basic information that is provided with commodity discriminator 2 in the supervisory card 3, if commodity discriminator 2 can read the basic information in the supervisory card 3, then commodity discriminator 2 is true, otherwise, then commodity discriminator 2 is false.

Commodity anti-counterfeiting identification methods are as follows:

The RFID tag 1 of the product stores a product ID number (each RFID tag 1 corresponds to a unique product ID number), a second verification code, and encrypted product information.

There is a product information database stored in the product authenticator 2. The product information database includes: the product ID number of the product, the A3 encryption algorithm template and the key algorithm template. Different merchants correspond to different key algorithm templates. The template encrypts the product information of the product.

Commodity identifier 2 is installed in various shopping malls or in other places that need to identify the authenticity of commodities. When the commodity with RFID tag 1 is close to commodity identifier 2, commodity identifier 2 reads the commodity ID number in RFID tag 1, and Check whether the product information database of commodity discriminator 2 exists this commodity ID number, if do not exist, commodity discriminator 2 stops discriminating, and sends alarm message; If exist, commodity discriminator 2 will produce a random data of 16 bytes, simultaneously Read in the product ID number of the product, extract 16 bytes as the key, perform A3 encryption calculation, generate a 6-byte first verification code, and read the second verification code pre-stored in the RFID tag 1, The encryption algorithm and the key of this second verification code and the first verification code are the same, compare whether these two verification codes match, if they do not match, then the product authenticator 2 stops the identification, and sends an alarm message; if it matches, the product identification Device 2 decrypts the product information encrypted in RFID tag 1 of the read product (commodity information encryption and decryption both use the MD5 algorithm, and the encryption and decryption keys are the same.), the decryption verification is unsuccessful, and the product authenticator stops identifying; If the decryption is successful, the commodity information is displayed.

The encrypted information in the RFID tag 1 of the commodity includes one or more of the following: commodity origin, commodity designated sales area, commodity model information, commodity production date information and commodity quality grade. For example, when the designated sales area of the product read by the product discriminator 2 does not match the actual sales area, the market supervisors can confirm that the product is sold by the merchant.
