the video computing cloud server is used for triggering the video domain gateway and the processor to execute corresponding processing on request information sent by a user;

the processor is used for establishing video sharing service based on the multi-trust domain trusted video sharing system after receiving a video sharing request, recording the data content, the sharing duration and the consumed video computing resources of the shared video in an authorization list, and carrying out charging statistics according to a preset charging strategy according to the authorization list;

the processor further comprises:

and the block chain node is used for verifying the attribution information of the video acquisition equipment, the attribution information of the shared video and the attribution information of the video computing resource among the multiple trust domains, and recording each attribution information after the verification is passed.

6. The system of claim 5, wherein the system further comprises a controller configured to control the controller,

the block chain node is further used for verifying the trust domain to which the video acquisition equipment among the multiple trust domains belongs, the video acquisition equipment to which the shared video belongs and the video server or video computing cloud server to which the video computing resource belongs, and recording all attribution information passing verification on the equipment trust list; and updating the equipment trust list after each new shared video exists, and storing the equipment trust list before updating and the equipment trust list after updating.

7. The system of any of claims 5-6, wherein authorization information between devices is also recorded in the authorization list, the processor further comprising:

and the intra-domain block chain node is used for carrying out identity verification on the equipment sending the video sharing request, judging whether the equipment sending the video sharing request is authorized or not according to the authorization list after the identity verification is passed, and carrying out video sharing if the equipment sending the video sharing request is authorized.

8. The system of any one of claims 5-6, wherein the processor further comprises:

the block chain node is used for calculating resources required by video collaborative analysis according to the resource use conditions of each video server and the video computing cloud server in the multi-trust domain trusted video sharing system after the received video collaborative analysis request; and carrying out collaborative analysis on the video content corresponding to the video collaborative analysis request through the calculated resources, and recording equipment for providing the resources and the provided resource conditions in the authorization list so as to carry out charging statistics.
