基于区块链信用体系的分布式数字版权管理机制
为了提升数字版权管理机制的效率，为去中心化内容分发网络中的版权保护问题提供解决方案，提出一种基于区块链信用体系的分布式DRM（digital right management）机制。利用区块链增信体制及智能合约技术，该DRM机制设计了去中心化分布式网络环境中的版权交易过程，实现版权交易过程的不可逆加密记录，并针对内容分发应用的实际需求对分布式账本的数据结构作出轻量化调整。仿真测试和结果分析表明，基于该机制可为构建出高性能低开销的分布式内容分发系统提供技术支撑，并且相较于传统DRM机制该机制具备高度的灵活性和可扩展性。
In order to improve the efficiency of Digital Right Management mechanism and provide solutions to copyright protection in decentralized content delivery networks, this paper proposed a distributed DRM mechanism based on blockchain. The mechanism designed procedures of copyright transactions in decentralized environment and made adjustment to data structure in blockchain according to demands of content distribution application. Simulation results demonstrate that the proposed mechanism can support DRM system effectively with only 6.7% overheads. Moreover, compared with traditional DRM mechanism, the proposed mechanism is of high scalability and flexibility.
