Problems solved by technology

However, since the two-dimensional code is a regular square graphic code composed of multiple squares, the coding method is simple, which makes the two-dimensional code very easy to generate, and even the hand-painted two-dimensional code can be effectively recognized, so it cannot satisfy the needs of individuals or enterprises. The security requirement that the graphic code is not easy to be copied or tampered with

Embodiment Construction

[0029] In order to improve the security of the graphic code, the application provides a graphic code and a method for generating the graphic code. The following describes the embodiments of the present application in conjunction with the accompanying drawings.

[0030] see figure 1 , figure 1 It is a schematic diagram of a graphic code provided by the embodiment of this application. Such as figure 1 As shown in the graphic code, the outline of the first character is used as the outline of the graphic code. Wherein, the first character may be an English letter, an Arabic numeral, a Greek letter, or the like. In a specific application process, the first character can be set according to actual application requirements, which is not limited herein.

[0031] In practical applications, the size of the graphic code can be set according to the amount of data to be stored and actual application requirements. In addition, in the process of embedding data, the first character can ...

Abstract

The invention provides a graphic code, a graphic code generation method and a graphic code jet printing method. According to the invention, the contour of a first character is used as the contour of the graphic code, a graphic positioning symbol and a data embedding area are included in the contour of the graphic code, the graphic positioning symbol is used for positioning the graphic code and thedata embedding area, the data embedding area comprises a binary dot matrix, the binary dot matrix is obtained by performing binary graphic coding on original data, the binary dot matrix is a graph composed of the first lines and the second lines, compared with a two-dimensional code composed of square blocks, the dimension of graph coding of the data is reduced, and under the condition of equivalent data, the area occupied by the graph code corresponding to the data in the graph code is reduced, so that based on this, the difficulty of generating, copying and tampering the graphic code can beimproved by reducing the size of the graphic code, and the security of the graphic code is improved.

Description

technical field [0001] The present application relates to the technical field of graphic codes, in particular to a graphic code and a method for generating the graphic code. Background technique [0002] Graphic coding refers to transforming data carrying certain information into graphic arrangement according to set rules, that is, information graphics. The graphic design requirement of graphic coding is reliable identification. In daily life, widely used graphic codes mainly exist in the form of two-dimensional codes. However, since the two-dimensional code is a regular square graphic code composed of multiple squares, the encoding method is simple, resulting in the easy generation of the two-dimensional code, and even hand-painted two-dimensional codes can be effectively recognized, so it is impossible to satisfy the needs of individuals or enterprises. The security requirement that the graphic code is not easy to be copied or tampered with. Contents of the invention ...
