Two-dimensional code based associated anti-counterfeiting method and verification method

Abstract

The invention is applicable to the technical field of anti-counterfeiting and electronics, and provides a two-dimensional code based associated anti-counterfeiting method. The method includes: a cloud server receives a production identification code S1, a package identification code S2, product characteristic information S3 and large package identification code P4 of a product inputted by a manufacturer; the cloud server combines the S1, the S2 and the S3 to a high-dimensional vector S, generates the package identification code, the production identification code, the P4 and the product characteristic information to a high-dimensional vector P, establishes a mapping relationship between the P and the S, respectively encrypts the S and the P by the aid of an AES (advanced encryption standard) algorithm to obtain a corresponding point S' of the S and a corresponding point P' of the P, encodes the S' and the P' to obtain a two-dimensional code S'' and a two-dimensional code P'' and sends the two-dimensional codes S'' and P'' to a manufacturer printer to enable the manufacturer printer to print the S'' on the product and the P'' on a small package of the product. The two-dimensional code based associated anti-counterfeiting method has the advantages of good anti-counterfeiting effect.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting and electronics, and in particular relates to an associated anti-counterfeiting method and verification method based on a two-dimensional code. Background technique [0002] Anti-counterfeiting technology refers to the measures taken to achieve the purpose of anti-counterfeiting. It can accurately identify the authenticity within a certain range and is not easy to be imitated and copied. Simply put, it is the technology to prevent counterfeiting and counterfeiting. A preventive technical measure taken to protect the corporate brand, protect the market, and protect the legitimate rights and interests of consumers. [0003] The shortcomings of the existing anti-counterfeiting technology: At present, most of the anti-counterfeiting technologies on the market use special special paper, special ink, printing patterns, and hollowing technology for anti-counterfeiting. The commonality of these technol...
