论文摘要
每天都会生成大量的多媒体数据（即文本，音频，视频，图形和动画）。通常，多媒体数据由多媒体服务提供商维护的平台管理，这些平台通常是使用集中式体系结构设计的。但是，这种集中式建筑可能导致单点失败和有关特许权使用费或其他权利的争议。很难确保版权协议中列出的义务的数据完整性和跟踪履行。为了解决这些问题，在本文中，我们为多媒体数据管理提供了基于区块链的平台体系结构。我们对身份管理采用自我主持的身份，并设计一种基于多层次的功能来访问控制。我们使用建议的方法实现概念验证原型，并使用用例对其进行评估。结果表明，所提出的方法是可行的，并且具有可扩展性能。
Massive amounts of multimedia data (i.e., text, audio, video, graphics and animation) are being generated everyday. Conventionally, multimedia data are managed by the platforms maintained by multimedia service providers, which are generally designed using centralised architecture. However, such centralised architecture may lead to a single point of failure and disputes over royalties or other rights. It is hard to ensure the data integrity and track fulfilment of obligations listed on the copyright agreement. To tackle these issues, in this paper, we present a blockchain-based platform architecture for multimedia data management. We adopt self-sovereign identity for identity management and design a multi-level capability-based mechanism for access control. We implement a proof-of-concept prototype using the proposed approach and evaluate it using a use case. The results show that the proposed approach is feasible and has scalable performance.
