Abstract

The invention provides a nested QR code encoding method, which comprises the steps : S1, establishing a paternal QR code data set and a child QR code data set, the child QR code data set comprising one or more combinations of type information, mark information and permission information of a parent QR code, and sequence information; S2, forming a paternal QR code by adopting paternal QR code data;S3, forming a plurality of child QR codes arranged in sequence by adopting the child QR code data set, wherein the sizes of the child QR codes are the same as those of the positioning points of the paternal QR code; and S4, capturing data, sizes and coordinates of the paternal QR code positioning points, and sequentially placing the plurality of child QR codes at the positions of the paternal QRcode positioning points according to the sequence information. The technical problem of data security when the QR code is used as an information carrier for circulation is solved, and tampering of QRcode data is avoided, and information effectiveness is guaranteed.

Description

technical field

[0001] The invention relates to the field of software methods, in particular to two-dimensional code technology. Background technique

[0002] Two-dimensional code, as an important contemporary coding technology, is widely used in high-tech industries, storage and transportation industries, wholesale and retail industries and other industries that need to quickly label information on items. Its data capacity, recognition speed, recognition security and recognition diversity are all important considerations for the development of QR codes.

[0003] Prior art one is a Chinese patent application whose patent publication number is CN109948764A, and the technical scheme is as follows: figure 1 As shown, it discloses an anti-counterfeiting two-dimensional barcode system and its encoding method. The disadvantage of prior art 1 is that: due to the common two-dimensional code with clear code characteristics, the decoding technology is an open technology, and if Fi...
