Abstract

The invention discloses a method and device for obtaining information from a display screen and transmitting the information, and the method comprises the steps: carrying out the encryption operationof a first dynamic password in a synchronous dynamic token through a formula stored in a first single-chip microcomputer, generating a ciphertext, and enabling the ciphertext to be displayed in the first display screen; enabling a first camera of a second single-chip microcomputer to read the ciphertext in the first display screen of the first single-chip microcomputer and sending the ciphertext to a server through a network for decryption operation, wherein the first single-chip microcomputer and the second single-chip microcomputer are connected through a connecting plate or a hollow pipe. Encrypted information in the first single-chip microcomputer is read through the second single-chip microcomputer camera, ciphertext transmission is achieved, and the possibility that original text information is directly obtained is prevented.

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 information from a display screen by using a camera to realize one-way transmission of information and stand-alone storage and calculation of information. [0004] In order to achieve the above object, the present invention provides a method for obtaining and ...
