System for realizing one-way transmission based on high-definition multimedia interface and dynamic two-dimensional code

Abstract

The invention discloses a system for realizing audio-video and data one-way transmission under a network isolation state based on a high-definition multimedia interface and a dynamic two-dimensional code. The system comprises an intranet, an analysis server, a loudspeaker, a high-definition wire rod, an extranet, a PC, and a sound acquirer; the analysis server is accessed into the intranet; the analysis server is connected with the loudspeaker; the PC is accessed into the extranet; the PC is connected with the sound acquirer; and the analysis server is connected with the PC through the high-definition wire rod. By use of the system disclosed by the invention, the external network system can safely transmit audio-video stream and two-dimensional code data to the internal network in real time through the high-definition multimedia interface under the network isolation state; the internal network analysis server acquires the audio-video stream in real time, extracts a two-dimensional code, decodes the related information of the two-dimensional code picture, saves and manages the related information, and then prompts whether the feedback information decoding is successful through the voice.

Description

technical field [0001] The invention belongs to the field of information security, and specifically relates to a system for one-way transmission of audio, video and data under network isolation based on high-definition multimedia interface and dynamic two-dimensional code video synthesis, and more specifically relates to a data security under the condition of isolation between internal and external networks Transmission system. Background technique [0002] With the continuous maturity and development of the Internet of Things + conceptual products, various applications or data systems will always be connected to the network in some form and finally connected to the Internet (public network). In many cases, it is necessary to extract the The data is sent to the outside in real time. However, the form of information security is becoming more and more serious. Once a system with confidentiality requirements is connected to the network, even if technologies such as firewalls a...

Problems solved by technology

[0004] 2. Physical gatekeeper technology is being gradually promoted, but there are problems such as high procurement and use costs, complex technical configuration, and if the configuration is not strict enough, it will expose and damage the internal system.

[0008] It can be seen from the introduction that the above solutions are all improved for the interaction between internal and external networks. Although they have positive significance, they still have some inapplicability. The first solution is transferred through the console, which needs to be connected The internal and external networks still have not really achieved pure physical isolation

The second solution requires external equipment and manual scanning and reading, which is not feasible

Although the third solution can automatically realize the one-way interaction of internal and external network information, the accuracy of the recognition rate is not high when the image is collected by an external camera, and it is easily affected by the environment and has poor stability.
