Problems solved by technology

[0005] This application is used to solve the shortcomings of the two-dimensional code encoded by the existing coding method, which has few valid data stored in the coding area, few personalized features of the two-dimensional code, and is difficult for the public to identify. In addition, the coding rules of the existing two-dimensional code are fixed Coding guidelines that make QR codes vulnerable to forgery or tampering

Abstract

The present application relates to the field of two-dimensional codes, and in particular, to a two-dimensional code, an encoding and identification method thereof, and a product with an anti-counterfeiting function. The two-dimensional code comprises a graphic area and an encoding area; the graphic area comprises an outer contour area and an inner contour area for positioning a range and an orientation of the encoding area; the encoding area is located between the outer contour area and the inner contour area, and is composed of a plurality of symbols, and the symbols fill the entire encodingarea without overlap; and the symbols of the encoding area are used to store user data according to a predetermined encoding rule. According to the two-dimensional code provided by the present application, more data can be stored in the encoding area with the same area.

Description

technical field [0001] This application relates to the field of two-dimensional codes, in particular to a two-dimensional code and its coding, identification method, and products with anti-counterfeiting functions. Background technique [0002] The traditional two-dimensional code is usually a rectangular pattern composed of black and white dot matrix, which contains a special positioning pattern inside, such as the "back" positioning pattern of the quick recognition two-dimensional code (QR code), such as figure 1 shown. The recognition program determines the range and size of the two-dimensional code by recognizing the positioning pattern. Generally, in order to quickly and accurately locate the identification program, the positioning pattern in the traditional matrix two-dimensional code is usually large in size, which will reduce the effective user data stored in the two-dimensional code coding area. If more data needs to be stored, the size and range of the two-dimens...
