Abstract

The invention discloses a two-dimensional code big data secure transmission device based on dynamic multistage encryption and decryption, and the device comprises a first data exchange interface whichis used for obtaining and sending to-be-exchanged data information; a data encryption module which is used for receiving the to-be-exchanged data information and carrying out dynamic multistage encryption; a two-dimensional code image generation module which is used for encoding the encrypted to-be-exchanged data to generate a two-dimensional code image; a two-dimensional code display module which is used for displaying the two-dimensional code image; the acquisition module is used for acquiring the two-dimensional code image; a two-dimensional code image recognition module which is used forrecognizing the collected two-dimensional code image and extracting feature data information; a data decryption module which is used for carrying out dynamic multistage decryption on the two-dimensional code feature data information; and a second data exchange interface which is used for outputting the decrypted exchange data; according to the invention, the data transmission capacity and the datatransmission security are greatly improved.

Description

technical field [0001] The invention relates to the technical field of data security transmission, in particular to a two-dimensional code large data security transmission device based on dynamic multi-level encryption and decryption. 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 device through the terminal camera of the external network device; [0005] (3) Perform decoding calculation on the terminal equipment of the external network device, and finally obtain the exchanged data; [0006] This method can transmit less data capacity, and will cause data insecurity. ...
