Abstract

The present invention discloses a unidirectional optical path data importing apparatus based on data image encoding and decoding technique which can automatically, unidirectionally and safely transmit data of external network to the internal network. The invention are achieved by the following technical solutions, the device includes an exterior network terminal, a display, an image acquisition apparatus and an internal network terminal, wherein, the external network terminal is connected to the display through data lines, the image acquisition apparatus is connected to the internal network terminal through data lines, and the display is provided adjacent to the image acquisition apparatus; the exterior network terminal contains a data management module, a data image coding module and an image display module; the internal network terminal includes a video capturing module, an image processing module, a data image decoding module, a verifying and error correction module, and a data frame assembling module. The device has advantages of simple hardware structure, low cost, intuition to inform users whether it is isolated or unidirectional, easy application and significant social and economic benefits.

Description

technical field [0001] The present invention relates to the technical field of network security isolation and information transmission, and more specifically relates to a data import device for automatically, unidirectionally and securely transmitting data from an external network to an internal network under the condition of physical isolation. Background technique [0002] State organs, military, government departments, industries (finance, taxation, transportation, etc.), and enterprises in the construction of information, in order to ensure information security and confidentiality, according to the "People's Republic of China Protection of State Secrets Law", all adopt the construction of internal computer networks, And "physical isolation" from other computer networks. While effectively solving the security isolation, it has formed an obstacle for the internal network to obtain external network information. For the internal network that transmits and processes confiden...
