AI Technical Summary

Technical Problem

Existing QR codes are easily copied and counterfeited, lacking image-level anti-counterfeiting features, resulting in low anti-counterfeiting security and low counterfeiting costs.

Method used

By performing a binary inversion operation on specific dots of a QR code, an anti-counterfeiting QR code is generated. Combined with a remote anti-counterfeiting service platform, dual verification is performed on both the text content and the dot matrix level to ensure that each object to be anti-counterfeited has unique anti-counterfeiting text and inverted dots.

Benefits of technology

It effectively distinguishes between genuine and counterfeit products, enhances anti-counterfeiting reliability, and makes it impossible for counterfeiters to replicate the correct inversion point. It is low-cost and highly compatible, and suitable for anti-counterfeiting scenarios of various commodities, invoices, and certificates.

Abstract

The application relates to the field of two-dimensional code anti-counterfeiting technology, in particular to a QR two-dimensional code anti-counterfeiting method and a QR two-dimensional code anti-counterfeiting system. The QR two-dimensional code anti-counterfeiting method utilizes the fault-tolerant mechanism of the QR two-dimensional code, carries out a binary inversion operation on 1-N dot matrices selected from a content area or a fault-tolerant area through a preset selection algorithm after a standard QR two-dimensional code image is generated. The number of inverted dots is determined by the two-dimensional code dot matrix specification, and the inverted dot position is uniquely determined by the text content carried by the two-dimensional code and the total dot matrix number, so that one product corresponds to one code. Since the number of inverted dots is extremely small, the normal reading of the two-dimensional code is not affected. During anti-counterfeiting verification, a remote service platform first compares the two-dimensional code text content, and then compares the dot matrix details, and judges the authenticity by detecting whether the preset inverted dots exist. The application has the advantages of strong compatibility, high anti-counterfeiting security, low cost, traceability and anti-channeling, and is suitable for various anti-counterfeiting scenes such as commodities, bills and certificates.
