Problems solved by technology

[0003] However, the form of a square QR code is fixed and single. When using a square QR code, a square area is required, so it is difficult to use in a scene where a square area cannot be provided.
For example: in the stamp, the five-pointed star area of ​​the stamp cannot use a square QR code
It can be seen that the usage scenarios of square QR codes are relatively limited

Abstract

The invention relates to the field of information security, and provides a two-dimensional code generation method and device. The two-dimensional code is provided with a five-pointed star outer frame, and a plurality of circumferences are made with different radiuses with the center point of the five-pointed star outer frame as the circle center. Performing sub-lattice segmentation on the plurality of circumferences to obtain a plurality of sub-lattices in the pentagram outer frame; in the pentagram outer frame, taking every four circumferences as a group in the direction from the outer ring to the inner ring, determining a sub-lattice in a circular ring formed by two innermost circumferences as a separation sub-lattice, and determining a sub-lattice in two circular rings formed by three outermost circumferences as an information filling sub-lattice; and performing data filling in the information filling sub-grids to obtain the two-dimensional code. According to the invention, the applicability of the two-dimensional code can be improved.

Description

technical field [0001] The present application relates to the field of information security, and in particular, to a method and device for generating a two-dimensional code. Background technique [0002] The current mainstream QR code is a square QR code, which has been applied to various scenarios. [0003] However, the square QR code has a fixed and single form. When a square QR code is used, a square area needs to be used, so it is difficult to use it in a scenario where a square area cannot be provided. For example: in the stamp, the square QR code cannot be used in the five-pointed star area of ​​the stamp. It can be seen that the usage scenarios of square QR codes are relatively limited. SUMMARY OF THE INVENTION [0004] Based on this, the present application proposes a method and device for generating a two-dimensional code, so as to make the two-dimensional code use a wider range of scenarios and improve the applicability of the two-dimensional code. [0005] In...
