Description

Technical Field

[0001] The present invention relates to product anti-counterfeiting identification, and in particular to a packaging printing and anti-counterfeiting identification system and method based on a variable two-dimensional code. Background Art

[0002] With the continuous development of information technology, more and more companies use the one-to-one-code technology to achieve product anti-counterfeiting identification. The core of the one-to-one-code technology is that each product has a unique code. At present, most of the market uses QR codes as the unique identity code of products for anti-counterfeiting, that is, each product packaging has a unique QR code logo.

[0003] The traditional method of printing QR codes is to import the QR code data into the coding equipment system, generate the QR code through the QR code generator built into the coding equipment, and then print the QR code on the packaging surface. After printing, most companies do not conduct closed-loop verification of the QR code printing effect, and a small number of companies only use simple visual recognition technology to test whether the printed QR code can be recognized.

[0004] Therefore, the traditional QR code anti-counterfeiting identification system has the following main problems: 1) Traditional QR code printing, once the QR code data is leaked, it is easy to imitate in the market; 2) In the actual application link, anti-counterfeiting identification is only performed by scanning the QR code with a mobile phone. This anti-counterfeiting method is too simple and easy to be overcome. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a packaging printing and anti-counterfeiting identification system and method based on variable QR codes, which can effectively overcome the defects of the prior art that the QR codes are easy to imitate and the anti-counterfeiting identification effect is poor.
