Problems solved by technology
In addition to the advantages of being able to quickly and accurately identify data, two-dimensional codes also have some problems. To be precise, the shape is fixed. The algorithm mechanism of two-dimensional codes causes two-dimensional codes to follow its shape rules and does not allow any modification of the appearance outline. Modifications
At the same time, the situation of the three positioning points of the QR code is too unsafe. Any missing or interference of any of the three positioning points will cause the entire QR code to fail.
[0003] In the existing seal encryption field, there are many encryption methods, such as Chinese invention patents CN 106570355 B, CN104504738 B, Chinese invention patent application CN 107944252 A and other disclosed seal encryption methods, all based on traditional two-dimensional codes, although specific The encryption methods are different, but none of them solve the problem of many restrictions on the use of traditional QR codes

specific Embodiment approach
[0019] refer to figure 1 , a specific embodiment of the present invention includes the following steps,
[0020] A. Set the five-pointed star frame;
[0021] B. Determine the positions of the five corners of the five-pointed star frame; fill in positioning feature 1 in each corner;
[0022] C. Fill encrypted data in other blank areas of the five-pointed star frame.
[0023] In step B, the positioning feature includes three similar triangles nested inside and outside, and the border width of the non-overlapping area of each triangle is 1 unit width.
[0024] In step C, an isolation interval 2 is set between the encrypted data and the positioning feature, and the width of the isolation interval 2 is 1 unit width.
[0025] In step C, the encrypted data is composed of several grids of the same size, and the side length of the grid is 1.5 unit width.
[0026] In step C, the pentagon surrounded by five vertex extension lines is defined as the main data area 3, and the five ind...

The invention discloses a five-pointed star encryption code generation method. The method comprises the following steps: A, setting a five-pointed star outer frame; b, determining five vertex angle positions of the pentagram outer frame; filling each vertex angle with a positioning feature; and C, filling other blank areas of the pentagram outer frame with encrypted data. The method can overcome the defects in the prior art, improves the recognition reliability of the encryption code, reduces the use limiting conditions of the encryption code, and is especially suitable for the encryption of aseal pattern.
Description
technical field [0001] The invention relates to the technical field of data encryption, in particular to a method for generating a five-pointed star encryption code. Background technique [0002] QRcode is a widely used identification code at present. The identification form of QRcode two-dimensional code includes positioning system, description system, data system and error correction system. The positioning system can be used to quickly find the position of the QR code, and at the same time, it can perform image projection perspective restoration and check the security of the QR code. After finding the location of the two-dimensional code correctly, the description system can be used to accurately understand the data format level information of the two-dimensional code. Through the data system and error correction system, the two-dimensional code that has been damaged to a certain extent can be perfectly repaired. The two-dimensional code represents the binary numbers o...
