Abstract

The invention discloses a two-dimensional code anti-counterfeiting mark image based on a dot matrix and an identification method thereof. That is to say, the content of the dot matrix anti-counterfeiting code is added on the basis of a traditional QR Code two-dimensional code, the two-dimensional code combined with the dot matrix anti-counterfeiting code can still be identified by the public two-dimensional code scanning application to obtain two-dimensional code information, and the two-dimensional code information can be scanned by the special anti-counterfeiting code scanning application tocarry out authenticity identification. The anti-counterfeiting two-dimensional code can achieve dual purposes, the anti-counterfeiting purpose is achieved by utilizing the universality of a traditional two-dimensional code, a user can rapidly use the anti-counterfeiting two-dimensional code conveniently, the anti-counterfeiting two-dimensional code can achieve the individuation purpose accordingto configuration of different parameters and coding schemes, and the decoding difficulty is improved.

Description

technical field

[0001] The invention belongs to the technical field of anti-counterfeiting marks, and in particular relates to a dot-matrix-based two-dimensional code anti-counterfeiting mark image and a recognition method thereof. Background technique

[0002] As China's economy grows, the prosperous trade market is booming, and the living standards of Chinese people are getting higher and higher. However, food safety and the proliferation of counterfeit and shoddy products are emerging one after another. Commodity counterfeiting has a long history, and the anti-counterfeiting and anti-counterfeiting methods corresponding to it are constantly updated with time. Due to the huge value behind counterfeit and shoddy products, many lawbreakers take risks and risk breaking the law to produce and sell counterfeit and shoddy products. The anti-counterfeiting and anti-counterfeiting means are just a powerful weapon to combat this phenomenon. They make the counterfeit and inferior go...

Embodiment Construction

[0026] In order to describe the present invention more specifically, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The anti-counterfeiting two-dimensional code anti-counterfeiting logo image based on the dot matrix of the present invention, on the basis of the traditional QR Code two-dimensional code, adds the content of the dot matrix anti-counterfeiting code, and combines a new anti-counterfeiting code, which is composed of the following parts:

[0028] S1. Identify the two-dimensional code area of ​​the image content data;

[0029] S2. Identify the dot matrix area of ​​the image anti-counterfeiting data.

[0030] The QR code area has the following characteristics:

[0031] S10. The image of the two-dimensional code area is divided into three positioning areas and a data area;

[0032] S11. The two-dimensional code area is formed by a plurality of square blo...
