Two-dimensional code anti-counterfeiting method, anti-counterfeiting two-dimensional code, and commodity anti-counterfeiting method

Abstract

The invention discloses a two-dimensional code anti-counterfeiting method. A computer program is employed for generating a conductive region in a two-dimensional code, and conductive ink is employed for printing the conductive region. Common ink is employed for printing a common region, thereby forming the two-dimensional code. The method comprises the steps: enabling the resistance information of the conductive region and the position information in the two-dimensional code to be corresponding to ID numbers and to be stored; forming a database; obtaining the ID numbers through reading the two-dimensional codes, wherein the resistance information of the conductive region and the position information in the two-dimensional code can be queried from the database; detecting the resistance value of the conductive region in the two-dimensional code, and comparing a detection value with a query value; judging the authenticity of the two-dimensional code. The method is simple and reliable, and 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 for a two-dimensional code, which is used to determine the authenticity of the two-dimensional code and realize the anti-counterfeiting of the two-dimensional code. The invention also relates to an anti-counterfeiting two-dimensional code and a commodity anti-counterfeiting method. Background technique [0002] With the development of market economy and globalization, counterfeit and shoddy products are increasingly rampant, which not only disturbs the market order, but also endangers the rights and interests of consumers. Therefore, using commodity packaging as a carrier and adding effective anti-counterfeiting measures to reduce the risk of counterfeiting has become the first choice for enterprises. The anti-counterfeiting packaging must meet three basic requirements, namely easy identification, low cost and difficult imitation. At present, as a widely used information carrier, QR code has the...

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.
