Big data secure transmission method based on matrix two-dimensional code

Abstract

The invention discloses a big data secure transmission method based on a matrix two-dimensional code. The method comprises the following steps: extracting to-be-exchanged data from a database for encryption; encoding the encrypted data to generate a two-dimensional code matrix sequence to obtain a two-dimensional code image; wherein special equipment authentication information and time authentication information are stored in the two-dimensional code matrix sequence; acquiring a two-dimensional code image through an acquisition module and then decoding to obtain final exchange data; wherein the step of generating the two-dimensional code matrix sequence comprises the sub-steps of segmenting and encrypting data information to be exchanged, and adding check information to form a plurality ofsegments of data; mapping the plurality of pieces of data into a plurality of two-dimensional code pictures; analyzing the two-dimensional code picture to obtain fragmented data, and assembling the fragmented data into complete text information. Authentication information is stored through the matrix two-dimensional code technology, the technical problems that in the prior art, the data transmission capacity is small, and data insecurity is caused are solved, and the data transmission capacity and the data transmission security are greatly improved.

Description

technical field [0001] The invention relates to the technical field of secure data transmission, in particular to a method for secure transmission of big data based on matrix two-dimensional codes. Background technique [0002] At present, the common data transmission method of the two-dimensional code is to scan the two-dimensional code and decode it to obtain the exchange information, that is, through the following steps: [0003] (1) Extract the data to be exchanged from the intranet database, encode the data, and generate a two-dimensional code pattern; [0004] (2) Capture the QR code image on the terminal display screen of the internal network system through the terminal camera of the external network system; [0005] (3) Perform decoding calculation on the terminal equipment of the external network system, and finally obtain the exchanged data; [0006] This method can transmit less data capacity, and will cause data insecurity.
