The invention provides a double-ID two-dimensional code microcode element encoding-decoding method and system, and the method comprises the steps: obtaining to-be-encoded original data preprocessing the to-be-encoded original data by binary conversion, redundant encoding and scrambling to generate first microcode element data; carrying out first microcode element image coding on binary data obtained through preprocessing in a code element space of the two-dimensional code, a first micro code element being implanted into a microcode element data area, and the microcode element data area being an area, except a positioning frame, in the two-dimensional code; and generating second microcode element data from the number of the first microcode elements in the microcode element data area, a preprocessing scheme and check and error correction codes, performing image coding on the second microcode element, and implanting the second microcode elements into the positioning frame. Microcode element coding is carried out on the basis of code elements, meanwhile, microcode element codes can be correctly analyzed on an output carrier, and correct analysis and reading of original two-dimensionalcode elements are not affected by existence of the microcode elements.
Description
[0001] related application [0002] This application claims the priority of the Chinese patent application with application number 202010023386.3 submitted on January 09, 2020, the entire content of which is incorporated herein by reference. technical field [0003] The invention relates to the technical field of two-dimensional code anti-counterfeiting, in particular to a method and system for encoding and decoding micro-code elements of a double-ID two-dimensional code. Background technique [0004] A two-dimensional code is an image representation of numbers and character codes, which is produced to facilitate the identification of automatic identification equipment. Two-dimensional codes that are widely used include QR codes, DM codes, PDF417 codes, etc. Among them, QR codes are adopted by popular mobile APP software such as WeChat and Alipay due to their fast recognition and high efficiency. Due to the adoption of popular mobile apps such as WeChat and Alipay, objectiv...
