Abstract

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.
基于区块链的视频版权检测
数字时代的版权侵权行为十分普遍,版权侦查在版权保护中发挥着有效的作用,其结果往往被保留为侵权上诉的证据。针对数字版权检测过程不公开导致结果不可靠、不可验证的问题,提出了一种基于区块链技术的链上与链下相结合的视频版权检测方案。首先从区块链下的视频内容中提取关键帧的特征指纹,然后调用智能合约在区块链上自动执行版权检测,以保证版权作品的原创性和检测结果的可验证性。最后,视频特征值永久且不可变地存储在区块链上。实验结果表明,调用链上的智能合约进行自动比较,既能保证准确率,又能获得可信的检测结果,保证了结果的透明性和公平性,也证明了方案的可行性。
