Even though the Internet promotes data sharing and transparency, however it does not protect digital content. In today’s digital world, it has become a difficult task to release a DRM (Digital Rights Management) system that can be considered well-protected. Digital content that becomes easily available in open-source environments will in time be worthless to the creator. There may only be a one-time payment to creators upon initial upload to a given platform after which time the rights of the intellectual property are shifted to the platform itself. However, due to the online availability of content, anyone can download content and make copies. The value of digital content slowly decreases, because the value of content can usually be determined through the difficulty of it’s accessibility. There is no way to track the leakage or copyright for the spread of digital material. In this paper, a distributed media transaction framework for DRM is proposed, which is based on the digital watermarking and a scalable blockchain model. In this paper, our focus is on improving the classic blockchain systems to make it suitable for a DRM model. The DRM model in this paper allows only authorized users to use online content and provide original multimedia content. While the digital watermarking is used to reclaim the copyright ownership of offline contents in the event when the contents are leaked.

尽管Internet促进了数据共享和透明性，但是它并不保护数字内容。在当今的数字世界中，发布DRM（数字版权管理）系统已被认为是受到良好保护的，这已成为一项艰巨的任务。在开放源代码环境中变得容易获得的数字内容将对创作者毫无价值。初次上载到给定平台后，创作者可能只能一次性付款，此后，知识产权将转移到平台本身。但是，由于内容的在线可用性，任何人都可以下载内容并进行复制。数字内容的价值缓慢下降，因为内容的价值通常可以通过其可访问性的难度来确定。无法追踪数字材料传播的泄漏或版权。本文提出了一种基于数字水印和可扩展区块链模型的DRM分布式媒体交易框架。在本文中，我们的重点是改进经典的区块链系统以使其适合DRM模型。本文中的DRM模型仅允许授权用户使用在线内容并提供原始多媒体内容。数字水印用于在内容泄漏时回收离线内容的版权。我们的重点是改进经典的区块链系统，使其适合DRM模型。本文中的DRM模型仅允许授权用户使用在线内容并提供原始多媒体内容。数字水印用于在内容泄漏时回收离线内容的版权。我们的重点是改进经典的区块链系统，使其适合DRM模型。本文中的DRM模型仅允许授权用户使用在线内容并提供原始多媒体内容。数字水印用于在内容泄漏时回收离线内容的版权。
