The process of matching the specific authenticity verification code is as follows: and acquiring the production time, the production address, the production serial number and the production supervisor information of the produced product, and processing the information through a Hash algorithm to obtain the authenticity verification code. The production time is detailed to the second, and the address is detailed to which production line produces the product in the workshop.
Step 2: the commodity verification code generation system encrypts the authenticity verification code to obtain authenticity verification information and a verification ID. The encryption processing procedure is that,
an encryption formula is selected for encryption, the encryption formula is,
in the formula (I), the compound is shown in the specification,
denotes the n subsequent values of the ith mapping iteration, i 1,2,3.. b-1, a-1, b, a, u are set values, and u e (1.64,2),
and u are both double-precision type numerical values, a 1,2,3n+1For the authenticity verification information, the values of a and b are determined according to the complexity of the user and the processorAnd selecting computing power. The verification ID is a secondary authenticity verification code obtained by carrying out secondary encryption on the authenticity verification code through a Hash algorithm.
And step 3: the commodity verification code generation system transmits the authenticity verification information and the verification ID to the enterprise private block chain system. The enterprise private blockchain system is used for storing the authenticity verification information and the verification ID, so that the enterprise private blockchain system can enter the enterprise private blockchain system for verification after authorization when authenticity investigation or evidence obtaining of products is required. Thereby making the public confidence stronger.
And 4, step 4: the enterprise private blockchain system transmits the authenticity verification information and the verification ID to each node of the enterprise private blockchain system through broadcasting and stores the authenticity verification information and the verification ID. The enterprise private blockchain system is used as a verification system for verifying the authenticity of a product, and is generally a verification system for verifying the authenticity of a manufacturer of the product. And related government departments or administrative departments to supervise and manage, so that the public credibility is strengthened. The number of nodes of the enterprise private blockchain system is generally about 5-10.
And 5: the enterprise private block chain system transmits the authenticity verification information and the verification ID to the public block chain verification system and transmits the authenticity verification information to the anti-counterfeiting code generation system. The public block chain verification system is generally a product authenticity verification system in the industry, is a system which can be verified by both public management and generally authorized persons, and the number of nodes is generally about 30-50.
Step 6: and the public block chain verification system broadcasts the authenticity verification information and the verification ID to each node of the public block chain verification system for storage. The public block chain verification system sends the authenticity verification information and the verification ID light waves to each node and then is used for authenticity verification of commodities in the later period, authenticity verification is that corresponding blocks are found through an authenticity verification information machine core, then the blocks are analyzed and compared, and the verification ID serves as a secret key with verification authority. Thereby preventing others from using a fake authentication system and a fake authentication to deceive the client.
And 7: the anti-counterfeiting code generation system generates two-layer duplex anti-counterfeiting codes by the authenticity verification information and the commodity official network information and/or the platform commodity information. The process of generating the two-layer duplex anti-counterfeiting code comprises the following steps: and generating by using a duplex anti-counterfeiting technology, wherein the duplex anti-counterfeiting technology is a Chinese code-through duplex anti-counterfeiting technology, commodity official network information and/or platform commodity information are/is used as anti-counterfeiting code information of a first layer, and authenticity verification information is used as anti-counterfeiting code information of a second layer. And the second layer of anti-counterfeiting code information in the generated duplex anti-counterfeiting code fails after being scanned once. The duplex anti-counterfeiting code verification process comprises the following steps: and after the duplex anti-counterfeiting code is scanned, extracting public commodity official network information and/or platform commodity information, simultaneously extracting authenticity verification information, sending the authenticity verification information to a public block chain verification system for verification, and returning a verification result by the public block chain verification system. If the verification is the first verification, the public block chain verification system returns a verification result after the verification process needs to be photographed and photographing information is transmitted to the public block chain verification system for broadcast storage; and if the verification is not the first time, the public block chain verification system directly returns the structure of the first verification and the photographing information in the first verification process.
And 8: and pasting the generated duplex anti-counterfeiting code on a corresponding commodity, pasting a waterproof layer outside after pasting the duplex anti-counterfeiting code, and meanwhile, coating an anti-counterfeiting verification scratch coating on the outer side of the waterproof layer. The duplex anti-counterfeiting code is a duplex two-dimensional code.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited thereto, and various equivalent modifications and substitutions can be made without departing from the spirit of the present invention.
