【摘要】：针对互联网生态下数字知识产权面临的版权登记、盗版猖獗和版权纠纷等问题,提出了去信任的数字作品数字版权唯一标识符(DCI)管控模型。首先,构建了基于区块链去中心化理念的端到端体系架构,区块链取代传统关系数据库作为核心存储机制,通过创建交易、构造区块、区块的合法性验证与链接构建了数字作品区块链的交易信息存储机制,保证版权信息不可篡改性和可溯源性;其次,提出了基于智能合约的数字化发行和流通协议,设计了版权登记、查询、转让三类合约,通过自动执行预设指令的方式产生交易,保证模型透明高效与自动化运作。理论分析和仿真表明,在数字作品区块链网络中,伪造区块攻击的概率趋近于零,与传统的基于可信第三方版权认证机制相比,该模型具有更好的架构安全性。实验结果表明,该模型降低了数字版权登记的门槛,增强了版权认证的权威,具有更好的实时性和鲁棒性。
[Abstract]:Aiming at the problems of copyright registration, rampant piracy and copyright disputes faced by digital intellectual property rights under the Internet ecology, this paper proposes a digital copyright unique identifier (DCI) control model for digital works that can be trusted. Firstly, an end-to-end architecture based on the idea of decentralization of block chain is constructed. The block chain replaces the traditional relational database as the core storage mechanism. The validity verification and link of blocks construct the transaction information storage mechanism of digital works block chain to ensure that copyright information can not be tampered with and traceability. Secondly, a digital distribution and circulation protocol based on intelligent contract is proposed. Three types of contracts, copyright registration, query and transfer, are designed to generate transactions by automatically executing preset orders, which ensure transparent, efficient and automated operation of the model. Theoretical analysis and simulation show that the probability of counterfeit block attack approaches zero in the digital work block chain network. Compared with the traditional copyright authentication mechanism based on trusted third party, the model has better architecture security. The experimental results show that the model reduces the threshold of digital copyright registration, enhances the authority of copyright authentication, and has better real-time and robustness.
