Embodiment Construction

[0034] Combine below Figure 1 to Figure 3 The embodiments of the present invention will be described in detail.

[0035] The two-dimensional code anti-counterfeiting method is characterized in that the steps are as follows:

[0036] (1) Use a 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;

[0037] (2) Create an ID number corresponding to the two-dimensional code according to the resistance value information of the conductive area and the position information in the two-dimensional code, so that the two-dimensional code and the ID number are in one-to-one correspondence;

[0038] (3) Store the resistance value information of the conductive area and the location information in the two-dimensional code corresponding to the ID number to form a database;

[0039](4) Read the two-dimensional code with the two-dimensio...

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...
