Problems solved by technology

The information of the QR code can be used for product information identification and traceability, but because the QR code is generated according to its coding rules, as long as the information is consistent, the same QR code can be repeatedly generated, so the QR code itself does not have anti-counterfeiting performance
[0005] However, there is no good solution for how to endow the anti-counterfeiting function based on the QR code itself and further confirm the validity of the information

Abstract

The invention discloses a two-dimensional code anti-counterfeiting method based on an error correction code domain. The two-dimensional code anti-counterfeiting method comprises the steps of generating an original two-dimensional code graph according to original data information; acquiring an error correction code domain pixel block; replacing or modifying a part of pixel blocks of the error correction code domain according to a preset mode, and generating an anti-counterfeiting two-dimensional code graph in combination with the information domain of the original two-dimensional code graph; and scanning the two-dimensional code graph of the product tagging area through a two-dimensional code scanning terminal, comparing the two-dimensional code graph with the anti-counterfeiting two-dimensional code graph serving as the anti-counterfeiting mark in information content and error correction code domain change records, and confirming whether the information is consistent or not. The method comprises using an error correction code domain, where the normal reading characteristic of the two-dimensional code cannot be influenced by changing the coding content; randomly replacing a part of pixel blocks in an error correction code domain to generate an anti-counterfeiting two-dimensional code graph; when the content of the two-dimensional code is acquired through an image, the two-dimensional code is compared with an anti-counterfeiting two-dimensional code serving as an anti-counterfeiting mark, whether the information is completely consistent or not is confirmed, and the anti-counterfeiting function of the two-dimensional code is achieved from the aspect of physical characteristics.

Description

technical field [0001] The invention relates to the application field of two-dimensional codes, and is particularly suitable for the fields of anti-counterfeiting and source tracing of the Internet of Things; in particular, it relates to an anti-counterfeiting method of two-dimensional codes based on an error correction code field. Background technique [0002] At present, with the development of the Internet of Things, two-dimensional codes are used as product ID marks, and it is becoming more and more a trend to obtain product-related information by scanning two-dimensional codes in the production, circulation, and consumption links. The information of the QR code can be used for product information identification and traceability, but because the QR code is generated according to its coding rules, as long as the information is consistent, the same QR code can be repeatedly generated, so the QR code itself does not have anti-counterfeiting performance . [0003] The struc...
