摘　　要：为提升社交网络中数字版权管理的服务质量和效率,提出区块链和社交网络传播链“双链融合”的安全传播机制,在此基础上设计一种数字版权服务区块链方案DCSChain(digital copyright service chain)。利用区块链链式结构特性保护数字媒体版权信息的存储安全,记录版权内容的发布与传播轨迹,通过公共节点作为通信媒介的方式实现双链之间的数据融合,使得版权数据的安全性在社交网络传播过程中得到可靠的有效保障。实验结果表明,该方案具有安全性和可信性,为社交网络环境下的数字媒体版权保护提供了一种解决思路和方法。To improve the quality and efficiency of digital rights management services for social networks,a dual-chain fusion secure propagation mechanism for both blockchains and social network distribution chains was proposed,as well as the digital copyright service blockchain solution named as DCSChain(digital copyright service chain)based on the dual-chain fusion.Features of the blockchain structure were employed to protect the storage security of digital media copyright information and the publishing and dissemination of copyright content were recorded.The public node was used as a communication medium to achieve data fusion between double chains,guaranteeing the security of copyright data during the social network transmission process.Experimental results show that the proposed scheme has security and credibility,and provides a solution and a method for digital copyright protection in the social network environment.
