Embodiment Construction

[0026] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] A large-capacity information transmission method based on a two-dimensional code of the present invention includes two processing processes of information sending and information receiving. In the information sending process, the information to be transmitted is encoded into a plurality of information two-dimensional codes, and the two The two-dimensional code decoding information is encoded into a decoded two-dimensional code; then the decoded two-dimensional code and the information two-dimensional code are combined to form a two-dimensional code unit; and each two-dimensional code unit is encrypted and encoded;

[0028] In the process of receiving the information, the information receiver first obtains the coded information, searches the coding code comparison table to determine the decryption method; then decrypts, sorts and splices ...

Abstract

The invention discloses a high-capacity information transmission method based on a two-dimensional code, and the method comprises the steps: to-be-transmitted information being coded into a pluralityof information two-dimensional codes in an information transmission process, and two-dimensional code decoding information being coded into a decoding two-dimensional code; combining the decoded two-dimensional code and the information two-dimensional code to form a two-dimensional code unit; encrypting and coding each two-dimensional code unit; in the information receiving process, an informationreceiver firstly acquiring coded information and searching a coded code comparison table to determine a decryption method; and decrypting, sequencing and splicing each piece of two-dimensional code information in the two-dimensional code units according to the decoding information, and splicing the information of each two-dimensional code unit in sequence. According to the invention, informationis encoded into a plurality of information two-dimensional codes, and the two-dimensional codes and the information two-dimensional codes are decoded and combined to form a decodable two-dimensional code unit. And the encoding, transmission and decoding of the information take one two-dimensional code unit as a unit, so that the information capacity and the information security degree of the two-dimensional code are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of information transmission, and relates to a large-capacity information transmission method, in particular to a two-dimensional code-based large-capacity information transmission method. Background technique [0002] A two-dimensional code is a black and white graphic distributed in a two-dimensional direction by a specific geometric figure to represent information, in which black and white are used to represent binary "0" and "1" bits. By converting the information into a two-dimensional code, which is then read by an image input device or an optical scanning device, the offline transmission of data is realized. [0003] However, with the continuous development of application fields and business needs, when two-dimensional codes are used as a large amount of data transmission method, the existing two-dimensional code technology is limited by the area of ​​a single two-dimensional code, and it is difficult ...
