AI Technical Summary
In existing technologies, the central node is overloaded, consumes a lot of resources, has low real-time performance, poor flexibility, and cannot guarantee security, resulting in low efficiency of secure video sharing.
By processing video data locally at edge nodes, the load on central nodes is reduced and transmission efficiency is improved; a three-dimensional dynamic permission control model of 'time-space-content' is introduced to achieve fine-grained permission management; an invisible watermark is embedded in the video stream and recorded on the blockchain to form a traceable data flow evidence chain; and by combining private protocols with national standard cascading mechanisms, the sharing needs inside and outside the system can be flexibly adapted.
It improves the efficiency of secure video sharing, reduces the load on the central node, increases transmission efficiency, enables fine-grained access control and data traceability, and ensures the security and flexibility of the system.
