An anti-counterfeiting two-dimensional code traceability label and its generation method

Abstract

The invention relates to an anti-counterfeiting two-dimensional code tracing label. The anti-counterfeiting information layer on the main body of the label is printed by a two-dimensional code and an anti-counterfeiting verification image wherein the latter is a local image randomly cut from the two-dimensional code and the latter corresponds to the two-dimensional code in a one-on-one relationship. The two-dimensional code tracing label generating method comprises: generating a two-dimensional code and randomly cutting the localities of the two-dimensional code; saving the two-dimensional code and the cut image in a database in the form of image; bonding and establishing a one-on-one relationship between the two-dimensional code and the cut image; printing the two-dimensional code and the bonded cut image onto the main body of the label; setting the cut image in the two-dimensional scanning application so that it can be displayed on a browser when the two-dimensional code is scanned successfully; comparing by a user the cut image displayed on the browser with the cut image on the label to verify the authentication of the two-dimensional code label. In this manner, the anti-counterfeiting effect and security of the label are increased to prevent the replication and the reuse of the label.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to an anti-counterfeiting two-dimensional code traceability label and a generating method. Background technique [0002] Driven by market interests, unscrupulous traders use counterfeit and shoddy goods to infringe on the rights and interests of consumers, and also seriously damage the reputation and economic interests of regular manufacturers. In order to resist counterfeit and shoddy products, many manufacturers paste anti-counterfeiting labels on the products they produce and sell for identification. Two-dimensional code anti-counterfeiting labels are currently a more commonly used technical means. The QR code stores a lot of information such as the place of origin of the product, which can help consumers obtain relevant information about the product by scanning the QR code. [0003] The two-dimensional code has a traceability function, and can easily realize the re...

AI Technical Summary

Problems solved by technology

[0003] The two-dimensional code has a traceability function, and can easily realize the reproduction and reproduction of the two-dimensional code through various forms such as copying, scanning, printing, etc. Therefore, the security of the ordinary two-dimensional code label currently on the market is very low, and it is easy to be counterfeited by illegal traders. Consumers can't tell the authenticity of the obtained information and products only by scanning the QR code
