Method and tag based on two-dimension code anti-counterfeiting and tag manufacturing method

Abstract

The invention relates to a method and a tag based on two-dimension code anti-counterfeiting and a tag manufacturing method. The problem that law breakers decode through method of exhaustion by numeric code is avoided by combining with a two-dimension code and images and characters to anti-counterfeiting; the problem that the law beakers can directly see and scan images and characters is avoided by applying a second printing carrier to cover the images and characters; the two dimension code images which are produced by computers and the two dimension images which are read by an image reading device can be differentiated through the existence of the border of a first printing carrier and the second printing carrier, so that the problem that the law breakers decode the two dimension data base through the method of exhaustion is avoided; due to the fact that the second printing carrier is randomly attached on the first printing carrier, and the border between the first printing carrier and the second printing carrier and relative position information of the two dimension images are stored in data, and whether the position of the border is consistent or not can be analyzed and judged, so that the problem that the lawbreakers manufacture counterfeit tags by simulating manufacturing process of the tags can be prevented.

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 a two-dimensional 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 is diff...

AI Technical Summary

Problems solved by technology

[0008] 1. Consumers are easy to identify, without tools, or with simple tools; 2. Consumers can easily obtain real information and compare it with the product in their hands; 3. Logos are easy to print and make, so production Low cost; 4. The production technology of the logo cannot be obtained by using the reverse engineering principle of the logo itself; 5. The logos of each product are different, so the cost of copying by criminals 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.
