Problems solved by technology

[0002] The two-dimensional code is composed of some geometric patterns according to certain rules. It is a plane graphic that can carry data information. The two-dimensional code has the characteristics of wide coding range, large information capacity, and strong fault tolerance. Because the two-dimensional code has powerful information Bearing capacity, so it is used for the entrance of various platforms. Customers can read the connection information of the product through any scanning function. The ordinary QR code with clear code characteristics is easy to be copied due to the open technology. By imitating the website, it is easy to It is easy to impersonate product connection information
Ordinary two-dimensional codes with clear code characteristics cannot achieve the purpose of anti-counterfeiting, resulting in damage to the interests of consumers. At the same time, there are various interference factors in the recognition process of two-dimensional codes due to shooting factors, such as noise, rotation, and reflection and background interference

Embodiment

[0030] An anti-counterfeiting two-dimensional code, please refer to the accompanying drawing-1, which includes a two-dimensional code pattern composed of a position detection pattern and a coding area. The position detection pattern has four positioning marks, and one of the four positioning marks is The main positioning mark; the coding area is circular, and the coding area is located in the center of the entire two-dimensional code graphic, and the coding area contains binary data information.

[0031] Further, the position detection graphic is made of a bright and dark binary image as an object, and the position detection graphic is composed of light and dark to form three nested contours; the light and dark conditions of the four positioning marks in the horizontal and vertical directions are dark: bright: dark: Light:dark=1:1:1:1:1, wherein the peripheral contour perimeter of the main positioning mark is greater than the peripheral contour perimeters of the other three pos...

Abstract

The invention provides an anti-counterfeiting two-dimensional code and a generating, and a generation and detection identification method thereof. The anti-counterfeiting two-dimensional code is a two-dimensional code graph composed of a position detection graph and a coding area, the position detection graph is provided with four positioning marks, and one of the four positioning marks is a mainpositioning mark; coding region being circular, the coding area is located in the center of the whole two-dimensional code graph; wherein the coding region contains binary data information; wherein the binary data information comprises a data code, an error correction code, a mask and a random code; according to the method, through adding the random code information, the mask acts on the data code, the error correction code and the random code at the same time, the same character generates different coding area graphs, leakage of a data storage structure is prevented, meanwhile, in the detection and recognition process of the two-dimensional code, interference of noise, rotation, light reflection and the background can be effectively avoided, and the detection and recognition precision ofthe two-dimensional code is improved.

Description

technical field [0001] The invention relates to the field of two-dimensional codes, in particular to an anti-counterfeiting two-dimensional code and a method for generating, detecting and identifying the same. Background technique [0002] Two-dimensional code is composed of some geometric patterns according to certain rules, and it is a plane graphic that can carry data information. Two-dimensional code has the characteristics of wide coding range, large information capacity, and strong fault tolerance. Because two-dimensional code has powerful information Bearing capacity, so it is used at the entrance of various platforms. Customers can read the connection information of the product through any scanning function. The ordinary QR code with clear code characteristics is easy to be copied due to the open technology. By imitating the website, it is easy to It is easy to impersonate product connection information. Ordinary two-dimensional codes with clear code characteristics...
