Anti-counterfeit label manufacturing method based on two-dimensional graph code

Abstract

The invention relates to an anti-counterfeit label manufacturing method based on a two-dimensional graph code. Through the method, through whether a first printing carrier and a second printing carrier have a boundary or not, a two-dimensional graph code image generated by a computer can be distinguished from a two-dimensional graph code image read by an image reading device, so a problem that a two-dimensional graph code database can be cracked by lawless persons through a method of exhaustion can be solved; the second printing carrier is randomly pasted on the first printing carrier, the boundaries of the first printing carrier and the second printing carrier and relative position information of the two-dimensional graph code images are stored in the data, whether positions of the boundaries are consistent are analyzed and determined, so counterfeit labels are prevented from being manufactured by the lawless persons through simulating a label manufacturing method. Punching is carried out in picture and text areas, positions of holes are changed randomly, the lawless persons who simulate the labels are required to know about the positions of the holes and to punch and position accurately through a machine, through the method, counterfeit cost for the lawless persons increases.

Description

【Technical field】 [0001] The invention relates to an anti-counterfeiting method, a label and a label making method, in particular to a method for making an anti-counterfeiting label based on a two-dimensional graphic code. 【Background technique】 [0002] Anti-counterfeiting is to solve a problem, which is not easy to forge and easy to identify. The purpose of anti-counterfeiting is mainly to distinguish the products of different merchants. Before the development of computer, network and 3C technology, the main method of anti-counterfeiting is that consumers can directly identify the authenticity through the naked eye without tools. The principle of this anti-counterfeiting technology is to use special printing technology to make anti-counterfeiting signs, such as Holographic anti-counterfeiting, because this kind of printing technology is relatively difficult, especially the template is difficult to copy, so the cost of anti-counterfeiting is very high, it is difficult to k...

AI Technical Summary

Problems solved by technology

[0008] 1. Consumers are easy to identify (such as the above-mentioned texture identification is too complicated), without tools, or with the help of simple tools; 2. Consumers can easily obtain (such as through mobile phones) real information, and use it with their hands 3. The logo is easy to print and make, so the production cost is low; 4. The production technology of the logo cannot be obtained through the reverse engineering principle of the logo itself; 5. The logos of each product are different, so criminals can copy the cost will be high

[0009] However, the existing anti-counterfeiting technologies cannot all meet the above-mentioned requirements, so their anti-counterfeiting security is not high.
