Abstract

The invention provides a data transmission system. The system comprises a front-end subsystem, an imaging device, a photographing device and a post subsystem. The front-end subsystem is used for receiving original service data to be sent by an intranet customer service system through a data interface, splitting the service data into multiple data streams, encrypting the split data streams, and converting the data streams pattern information which can be displayed. The imaging device is used for displaying the pattern information. The photographing device is used for photographing a pattern on the imaging device. The post subsystem is used for receiving the pattern sent by the photographing device, decoding and converting the pattern into data streams, decrypting, merging and reorganizing the data streams to form the original service data, and sending the data to an extranet service network system through the data interface. Through the data transmission system, the data can be safely, efficiently and reliably transmitted between domains of different security levels.

Description

technical field [0001] The invention relates to the field of network technology and information security, in particular to a safe and efficient data transmission method and data transmission system based on different network domains. Background technique [0002] With the rapid popularization and development of the Internet, network information security threats have received increasing attention from relevant enterprises and government departments. Efficient and secure data transmission between network domains with different security levels has become an urgent need for important secret-related departments such as the government, military industry, and finance. Due to the high level of internal network security built by sensitive industry departments, data often needs to be transmitted across network domains to achieve information sharing between different industries and departments. In the existing technology, the network firewall technology has been unable to fully cope w...
