Abstract

The invention discloses an information display and reading method and device, and the method comprises the steps that a first single-chip microcomputer receives a verification code through a network,wherein the verification code is displayed in a first display screen; a second camera of a second single-chip microcomputer reads the verification code in the first display screen, encryption operation is conducted on the verification code through a formula, a ciphertext is generated, and the ciphertext is displayed in a second display screen of the second single-chip microcomputer; a first cameraof the first single-chip microcomputer reads the ciphertext in the second display screen and sends the ciphertext to a website server through a network for decryption and verification; and after theciphertext is received, the website server carries out decryption operation on the ciphertext. The characteristic of cameras and display screens read each other is utilized, one-way transmission of information is achieved, a second single-chip microcomputer can achieve stand-alone operation, and the network communication function is achieved through the first single-chip microcomputer.

Description

technical field [0001] The invention relates to information transmission, in particular to information collected by a camera for transmission. Background technique [0002] In the existing information transmission process, the code scanning method is used for information transmission, which is convenient and quick to use. And this structure can effectively allow the storage of information to achieve the effect of physical isolation. However, the traditional computer information generation and transmission process cannot achieve physical isolation, which has potential safety hazards. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a method of reading and transmitting information from a display screen by using a camera to realize one-way transmission of information and stand-alone calculation. [0004] In order to achieve the above purpose, the present invention provides a method for displaying and reading ...
