Anti-counterfeiting method of two-dimensional code, anti-counterfeiting two-dimensional code and commodity anti-counterfeiting method

Abstract

The anti-counterfeiting method of the two-dimensional code adopts the computer program to randomly generate the conductive area in the two-dimensional code, print the conductive area with conductive ink, and print the common area with ordinary ink to form the two-dimensional code. The resistance value information of the conductive area and the position information in the two-dimensional code are stored in correspondence with the ID number to form a database. By reading the two-dimensional code and obtaining the ID number, the conductive area in the two-dimensional code can be queried from the database. The resistance value information of the area and the position information in the two-dimensional code detect the resistance value of the conductive area in the two-dimensional code, and compare the detected value with the query value to determine the authenticity of the two-dimensional code. The detection and judgment method is simple and reliable. The anti-counterfeiting reliability of the two-dimensional code is high. The invention also provides an anti-counterfeiting two-dimensional code and a commodity anti-counterfeiting method.

Description

technical field [0001] The invention relates to an anti-counterfeiting method of a two-dimensional code, which is used for judging the authenticity of the two-dimensional code and realizing the anti-counterfeiting of the two-dimensional code. The invention also relates to an anti-counterfeiting two-dimensional code and a product anti-counterfeiting method. Background technique [0002] With the development of market economy and globalization, counterfeit and shoddy products are becoming more and more rampant, which not only disrupts the market order, but also endangers the rights and interests of consumers. Therefore, it has become the first choice for enterprises to use commodity packaging as a carrier and add effective anti-counterfeiting means to reduce the risk of counterfeiting. Anti-counterfeit packaging must meet three basic requirements, namely, easy identification, low cost and difficult imitation. At present, as a widely used information carrier, two-dimensional c...

Problems solved by technology

This solution uses VDP technology to randomly generate variable QR code anti-counterfeiting technology, but this solution can only be used for variable QR code anti-counterfeiting, and cannot be used for static QR code anti-counterfeiting

[0005] Therefore, the reliability, applicability and anti-counterfeiting cost of two-dimensional code anti-counterfeiting in the prior art still need to be improved.
