Two-dimensional graph coding anti-fake based method and tag and making method of two-dimensional graph coding anti-fake based tag

Abstract

The invention relates to two-dimensional graph coding anti-fake based method and tag and a making method of the two-dimensional graph coding anti-fake based tag. In the invention, a two-dimensional graph coding image generated by a computer and a two-dimensional graph coding image read by an image reading device can be distinguished through the existence of the a boundary of a first printing carrier and a second printing carrier, and therefore, the problem that a lawless person cracks a two-dimensional graph coding database through an exhaustion method; the second printing carrier is randomly bonded on the first printing carrier, the boundary of the first printing carrier and the second printing carrier and the relative position information of the two-dimensional graph coding image are stored in data, and whether the position of the boundary is consistent or not is analyzed and judged, and therefore, a counterfeit tag is prevented from being made by simulating the making process of the tag by the lawless person; an image-text area is punched, the position of a hole is randomly changed, and the lawless person needs to know the position of the hole and accurately position and punch through a machine if intending to simulate the tag, and therefore, the counterfeit cost is increased.

Description

【Technical field】 [0001] The invention relates to an anti-counterfeiting method, a label and a label making method, in particular to an anti-counterfeiting method based on two-dimensional graphic code, a label and the label making method. 【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 i...

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.
