Blockchain-Based Video Copyright Detection

Copyright infringements in the digital age are common, copyright detection plays an effective role in protecting copyright, and the results are often retained as evidence of infringement appeals. In this paper, we proposed a video copyright detection scheme combining on-chain and off-chain based on blockchain technology for the problems of undisclosed digital copyright detection process leading to unreliable and unverifiable results. Firstly, the feature fingerprints of the key frames are extracted from the video content under the blockchain, and then the smart contract was called to automatically perform copyright detection on the blockchain to ensure the originality of the copyrighted work and the verifiability of the detection result. Finally, the video feature value is permanently and immutably stored on the blockchain. Experimental results show that invoking the smart contract on the chain to automatically compare can not only ensure the accuracy rate, but also obtain credible detection results, ensure the transparency and fairness of the results, and also prove the feasibility of the scheme.
