论文摘要
版权检测是预防盗版的有效方法。但是，不信任的检测方可能导致伪造的检测结果。由于其信誉和侵犯性，区块链已应用于版权保护。先前的工作主要利用区块链用于可靠的版权信息存储或受版权保护的数字媒体交易。据我们所知，尚未解决可靠的版权检测问题。在本文中，我们提出了一个基于区块链的可靠版权检测架构，称为DCDCHAIN。在此架构中，检测机构首先检测到链条上的版权，然后将检测记录上传到区块链。由于可以公开访问区块链的数据，因此媒体提供商可以验证版权检测的正确性，并在有任何异议时诉诸智能合约。然后，智能合约通过验证链条上检测的正确性来仲裁争议。检测验证和挑选机制保证了版权检测的可信度。安全分析和实验模拟表明，数字版权检测体系结构是可信，安全和高效的。拟议的可靠版权检测方案对于版权保护非常重要。未来的工作是通过为各种数字媒体设计更有效的局部敏感哈希算法来改善该计划。
Copyright detection is an effective method to prevent piracy. However, untrustworthy detection parties may lead to falsified detection results. Due to its credibility and tamper resistance, blockchain has been applied to copyright protection. Previous works mainly utilized blockchain for reliable copyright information storage or copyrighted digital media trading. As far as we know, the problem of credible copyright detection has not been addressed. In this paper, we propose a credible copyright detection architecture based on the blockchain, called DCDChain. In this architecture, the detection agency first detects copyrights off the chain, then uploads the detection records to the blockchain. Since data on the blockchain are publicly accessible, media providers can verify the correctness of the copyright detection, and appeal to a smart contract if there is any dissent. The smart contract then arbitrates the disputes by verifying the correctness of detection on the chain. The detect-verify-and-arbitrate mechanism guarantees the credibility of copyright detection. Security analysis and experimental simulations show that the digital copyright detection architecture is credible, secure and efficient. The proposed credible copyright detection scheme is highly important for copyright protection. The future work is to improve the scheme by designing more effective locality sensitive hash algorithms for various digital media.
