Abstract
The invention relates to a method, system and device for generating an anti-counterfeiting code through a product number and a storage medium, and belongs to the technical field of anti-counterfeiting code generation methods. The method comprises the following steps: S1, generating a unique number P for a product number according to a preset rule, and obtaining a value N for a product sequence number in a preset length range; s2, AES encryption operation is carried out on the product number P and the product sequence number N, and an authentication code is obtained after a modulo algorithm is carried out; s3, combining the product number, the product sequence number and the authentication code into a plain code; s4, performing full-code conversion on the plain code to obtain an anti-counterfeiting code array; step S5, converting the anti-counterfeiting code array into an anti-counterfeiting code; the system comprises a character string generation module, an authenticationcode generation module, a plain code generation module, an anti-counterfeiting code array generation module and an anti-counterfeiting code generation module. The device comprises a memory and a processor; a computer program is stored on the readable storage medium, and the steps of the method are implemented when the computer program is executed; the encryption strength is high, and cracking is not easy.
Description
technical field [0001] The invention relates to a method, system, device and storage medium for generating anti-counterfeiting codes from product numbers, and belongs to the technical field of anti-counterfeiting codes. Background technique [0002] The problem of product counterfeiting has been around for a long time. Many companies have made great efforts in preventing and cracking down on counterfeiting, and have achieved certain results. However, counterfeiting and shoddy products are still repeatedly banned. In order to regulate the market order and prevent counterfeit and shoddy goods from impacting product prices, destroying product image, destroying product reputation, and destroying the product market, most manufacturers will print anti-counterfeiting codes on their products. [0003] At present, encryption generation algorithms for anti-counterfeiting codes emerge in an endless stream, but most encryption generation algorithms have the problems of insufficient encr...
