Product anti-counterfeiting method based on two-dimensional code

Abstract

The invention provides a product anti-counterfeiting method based on a two-dimensional code. The product anti-counterfeiting method mainly comprises the steps that product codes are compiled and converted into the character strings of a product; ECC encryption operation and coding are performed on original information of the product and the character strings of the product by an EK encryption key so that a two-dimensional code graph of the product is generated, and the two-dimensional code and the product codes are printed on one product; the two-dimensional code graph is read by identification equipment in use; the product information and the character strings carried in the two-dimensional code graph are obtained; authenticity of the product is judged through comparison of the product information; and the character strings of the product are inputted to a product verification inlet again so that the product codes are obtained, and authenticity of the product is judged again. With application of the technical scheme, the product codes are compiled by a manufacturer to form the character strings, compiling of the character strings is encrypted by the manufacturer, and the character strings are difficult to decode for counterfeiters so that correspondence of the character strings and the product codes is difficult, information of the character strings is identified by a user through browsing the website of the manufacturer and thus authenticity of the product can be accurately judged.

Description

technical field [0001] The invention belongs to the technical field of digital anti-counterfeiting, and in particular relates to a product anti-counterfeiting method based on a two-dimensional code. Background technique [0002] At present, all walks of life are paying attention to the application of two-dimensional code anti-counterfeiting technology. The core is to use the information hidden in the two-dimensional code to compare with the information on the product to help consumers identify the authenticity of the product. [0003] The two-dimensional code is distributed into black and white graphics in the direction of the two-dimensional plane according to certain rules through several specific graphics, and the data symbol information is recorded in it. In the code design and writing, the principle of "0" and "1" bit streams that constitute the internal logic basis of the computer is used, and multiple geometric shapes corresponding to the binary are used to represent ...

Problems solved by technology

[0006] The present invention aims at the problems in the prior art that the anti-counterfeiting function of the two-dimensional code printed on the product is poor, the information in the two-dimensional code is easy to be copied, and it is difficult for the user to distinguish the authenticity, and provides a product anti-counterfeiting method based on the two-dimensional code, which improves Anti-counterfeiting function of QR code
