Two-dimensional code label and its anti-counterfeiting method, method for verifying the authenticity of circulating commodities, and a printer for two-dimensional code images

Abstract

The invention discloses a two-dimensional code label, an anti-counterfeiting method thereof and a method for verifying authenticity of a circulating commodity, and Printer for two-dimensional code image, and belongs to Two-dimensional code anti-counterfeiting field, The objective of the invention is to solve the problem that a current printed two-dimensional code is not easy to imitate. The two-dimensional code label comprises a two-dimensional image, The two-dimensional code image is printed in at least two printing modes. a part of two-dimensional code image is printed in each printing mode;a two-dimensional code image area is printed in each printing mode; The two-dimensional code image information is distributed to different printer control modules through the distribution informationto be printed, all parts of image information distributed through the distribution information are transmitted and printed to form a two-dimensional code image corresponding to the complete two-dimensional code image information, and the effect is that the anti-counterfeiting capability of the current printed two-dimensional code is enhanced.

Description

technical field [0001] The invention belongs to the field of two-dimensional code anti-counterfeiting, and relates to a two-dimensional code and its anti-counterfeiting method, a printer for printing the two-dimensional code, and a commodity traceability method and platform. Background technique [0002] The QR code records product information. When the terminal scans the QR code, it will read a piece of information and feed it back to the cloud, and the cloud will judge whether the QR code is recorded in the cloud, so as to identify the authenticity of the product. Currently, most of the QR code images are printed Therefore, the applicant's prior application (Chinese invention patent application with publication number CN 107992907 A) discloses a two-dimensional code anti-counterfeiting printer, which aims to combine the platform with the stored image watermark template and the printer in the printer. The unique identifier is stored synchronously. In the QR code printing pr...

Problems solved by technology

[0003] In order to solve the problem of enhancing the ability of the current printed two-dimensional code to be difficult to be counterfeited, and the printing terminal does not record the two-dimensional code printed logo stored in the platform and its corresponding content with the image, the printed logo is not expressed by a fixed encryption algorithm. To improve the anti-counterfeiting ability of printing two-dimensional codes, the present invention proposes the following technical solution: a two-dimensional code label, including two-dimensional code images, the two-dimensional code images are printed by at least two printing methods, and each printing method prints Part of the two-dimensional code image, the two-dimensional code image area printed by each printing method, is formed by distributing the two-dimensional code image information to different printer control modules according to the distribution information, and the image information of each part of the distribution information distribution is transmitted and printed. The QR code image corresponding to the complete QR code image information
