A scheme of short video copyright storage based on lightweight blockchain technology
In the blockchain-based short video storage,the video data is directly uploaded to the chain,which is limited by block size and throughput,and generates huge network latency.Therefore,a scheme of short video copyright storage based on lightweight blockchain technology is proposed.In order to re-duce the amount of storage on the video information chain,a video uniqueness verification is construc-ted based on video image feature extraction technology,and a video certificate is constructed with other video information for on-chain storage.At the same time,in order to ensure the security of off-chain da-ta,the mapping between the original video data storage and on-chain storage of lightweight information is proposed based on IPFS technology.The lightweight video on-chain storage solution not only relieves the storage pressure of on-chain video data,but also ensures the storage security of video copyrights.Experimental result shows that our scheme is efficient on the storage of video copyrights with low net-work latency.
