A one-way data acquisition device and system based on air isolation

Abstract

The invention discloses a one-way data acquisition equipment and system based on air isolation, including data acquisition hardware equipment and data acquisition software system; the data acquisition hardware equipment part includes a data acquisition server, a graphic encoder, a high-definition identifier and a data storage server As well as the data storage library, the data acquisition software system includes a data sending unit and a data receiving unit. The beneficial effects of the present invention are: the first security domain sending unit and the dot matrix code identification camera of the second security domain physically completely prevent the existence of isolation equipment, network equipment and lines between the two security domains, and also completely prevent the existence of isolation equipment, network equipment and lines. Using the network connection of the security domain to carry out external intrusion, while integrating technical means such as dynamic encryption and decryption in the process of data transmission, dynamic identification and authentication of identity, and integrating the situational awareness of the entire data flow, the network security concept in the true sense is realized.

Description

technical field [0001] The invention relates to a data acquisition device, in particular to a one-way data acquisition device and system based on air isolation, and belongs to the technical field of data security acquisition and transmission. Background technique [0002] In recent years, the global network security situation has been severe. Personal information and commercial data have been leaked and used illegally on a large scale. Malicious network attacks against key information infrastructure have occurred frequently, and local network information stations around the world may break out at any time. Faced with the new situation, how to strengthen network security construction, better respond to network security threats, and more effectively safeguard national security. [0003] As the country has done a lot of work in the construction of network security prevention capabilities, it has achieved remarkable results. However, in terms of the integrity of network security...

Problems solved by technology

[0003] Based on the fact that the country has done a lot of work in the construction of network security prevention capabilities and achieved remarkable results, all industries still need to deal with the integrity of network security. The urgent need to establish, the ecological construction of network trusted identities still needs to be strengthened, and the network security guarantee system of key information infrastructure is still not perfect, so that the national network security guarantee capability still needs to be improved
