Abstract

The present application provides a method and device for unidirectional transmission of video structured data based on device attribute selection. The method includes: maintaining a whitelist based on the identified attribute information of the video surveillance device; before the end of the first detection period, if the data packet If the data carried in the video is structured video data, the structured video data will be repackaged and transmitted to the central network in one direction, and the attribute information of the data packet will be added to the white list; otherwise, the data packet will be discarded; At the end of a detection period, if the attribute information of the data packet is not in the white list, the data packet will be discarded; if the attribute information of the data packet is in the white list, and the data carried in the data packet is video structured data , the video structured data is repackaged and then transmitted to the central network in one direction; if the data carried in the data packet is not video structured data, the data packet is discarded. This method can reduce data transmission pressure.

Description

technical field [0001] The present application relates to the field of data security, in particular to a method and device for one-way transmission of video structured data based on device attribute selection. Background technique [0002] With the intelligent development of video IoT terminals, more and more video cameras have AI recognition functions, which can detect various alarm events and use structured data (for example, structured information extracted from pictures, pictures data, picture summary data, etc.) to the central server or platform. [0003] However, video smart cameras are usually deployed on edge networks (or low-security networks), and there are certain security risks if their video structured data is uploaded to the central network (or high-security networks). In the traditional technical solution, in order to be able to solve the data transfer from the low-security network to the high-security network, the gatekeeper technology is generally used. Bu...
