With the development of information technology, films, music, and other publications are inclined to be distributed in digitalized form. However, the low cost of data replication and dissemination leads to digital rights problems and brings huge economic losses. Up to now, existing digital rights management (DRM) schemes have been powerless to deter attempts of infringing digital rights and recover losses of copyright holders. This paper presents a YODA-based digital watermark management system (Y-DWMS), adopting non-repudiation of smart contract and blockchain, to implement a DRM mechanism to infinitely amplify the cost of infringement and recover losses copyright holders suffered once the infringement is reported. We adopt game analysis to prove that in Y-DWMS, the decision of non-infringement always dominates rational users, so as to fundamentally eradicate the infringement of digital rights, which current mainstream DRM schemes cannot reach.
随着信息技术的发展，电影、音乐和其他出版物倾向于以数字化形式发行。然而，数据复制和传播的低成本导致了数字版权问题，并带来了巨大的经济损失。到目前为止，现有的数字版权管理（DRM）方案对于阻止侵犯数字版权的行为以及挽回版权所有者的损失无能为力。本文提出了一种基于YODA的数字水印管理系统（Y-DWMS），采用智能合约和区块链的不可抵赖性，来实现一种DRM机制，一旦报告侵权行为，就无限放大侵权成本并挽回版权所有者遭受的损失。我们采用博弈分析来证明，在Y-DWMS中，不侵权的决策始终主导理性用户，从而从根本上根除数字版权侵权行为，这是当前主流DRM方案无法做到的。
