A method for generating and identifying an invisible two-dimensional code anti-counterfeiting label

Abstract

The invention provides a generation method for an invisible two-dimension code anti-counterfeit label. The generation method includes the following steps that anti-counterfeit information is input; whether encryption is needed or not is judged, and if yes, a next step is executed; otherwise, the next step is skipped to execute the follow-up steps; the anti-counterfeit information is encrypted to obtain encrypted information; the anti-counterfeit information or the encrypted information is coded to generate an invisible two-dimension pattern; the invisible two-dimension pattern is divided into a positioning code pattern and an information code pattern and generates corresponding two layers of films; at least two kinds of printing ink or carbon powder with different wave band photoreception are used for printing the positioning code pattern and the information code pattern on appointed positions of a bearing article respectively. The invention further relates to an identification method for the invisible two-dimension code anti-counterfeit label. Through the implementation of the generation method and the identification method for the invisible two-dimension code anti-counterfeit label, the label has the advantages of being good in anti-counterfeit effect and not prone to being counterfeited, the manufacturing process is simple, production cost is low, and coding information amount is large.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to a method for generating and identifying an invisible two-dimensional code anti-counterfeiting label. 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 a technology to prevent counterfeiting and counterfeiting. It is a preventive technical measure adopted to protect the corporate brand, protect the market, and protect the legitimate rights and interests of consumers. [0003] Among the currently used Fangwei products, among them, the first generation of anti-counterfeiting products is represented by laser anti-counterfeiting products, consumers do not have the ability to identify the authenticity of the label, the anti-counterfeiting effect is poor, and the label is ...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that, aiming at the defects of the prior art that the above-mentioned anti-counterfeiting effect is poor, it is easy to be forged, the production process is complicated, the production cost is high, and the Selfie effect with a small amount of encoded information does not meet the requirements, a self-timer is provided. A method for generating and identifying an invisible two-dimensional code anti-counterfeiting label with good anti-counterfeiting effect, not easy to be forged, simple production process, low production cost, and large amount of encoded information
