Video computing across trust domains based on blockchain

Smart city construction brings great development opportunities for the video surveillance industry, but it also brings significant challenges. With the development of Internet of things and artificial intelligence technology, video computing across different trust domains has become important and necessary for ensuring public safety and promoting smart city construction. With the continuous increasing of video front-end equipment and massive video data, trust and security problems across different domains, network bandwidth and computing resources are gradually becoming bottlenecks of video computing. We propose a solution based on integration of blockchain and Internet of things which brings together and distributes video data and computing resources to enhance the edge video computing capability. Blockchain provides a distributed solution for trust video computing across different trust domains. We evaluate the performance of blockchain-based video computing solution across different trust domains and the results show that this solution could provide trust video computing across trust domains feasibly and efficiently. This solution implies a new trigger of trust distributed applications and innovative trust economic ecosystem.
