A Big Data Secure Transmission Method Based on Matrix QR Code

Abstract

The invention discloses a large data secure transmission method based on a matrix two-dimensional code, comprising: extracting data to be exchanged from a database for encryption; encoding the encrypted data to generate a two-dimensional code matrix sequence, and obtaining a two-dimensional code image ;Proprietary equipment authentication information and time authentication information are stored in the two-dimensional code matrix sequence; the two-dimensional code image is collected through the acquisition module, and then decoded to obtain the final exchange data; the two-dimensional code matrix sequence is generated, including: Segment, encrypt, and add verification information to the data to be exchanged to form several pieces of data; map several pieces of data into multiple QR code images; analyze the QR code images to obtain fragmented data, and assemble them into complete text information; The present invention stores authentication information through the matrix two-dimensional code technology, solves the technical problem of less transmission data capacity in the prior art and causes data insecurity, and greatly improves the transmission data capacity and data transmission security.

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. Contents of the invention [0007]...
