摘要
传统基于第三方中心机构的版权登记存在效率低、成本高和隐私保护性差等问题,针对这些问题,将区块链与环签名技术运用于版权保护领域,提出一种基于区块链的数字版权存证系统模型。构建了基于联盟链的数字版权存证系统架构,利用区块链的去中心化、不可篡改和可追溯等特性保证存证的信息真实可信;对环签名技术进行改进,并利用改进的环签名技术保护创作者身份隐私;对PBFT算法进行改进,提升系统效率和可靠性。经分析与实验表明,该模型能降低版权登记经济成本,防止用户身份信息被非法获取,且具有良好的性能与安全性。
Traditional copyright registration on third party central agencies is low efficiency, high cost and poor privacy protection. To solve the above problems, the blockchain and the ring signature technology is applied to the field of copyright protection, and a digital copyright certificate storage system model based on block chain is proposed. Firstly,the copyright storage architecture based on the consortium blockchain is constructed, which ensures the authenticity and credibility of copyright information by using the decentralized, tamper-proof and traceable features of the blockchain.Secondly, the ring signature technology is improved and is used to protect the author’s identity privacy. Finally, the Practical Byzantine Fault Tolerance(PBFT)algorithm is improved to improve the system efficiency and reliability. The experimental results show that the model reduces the threshold of copyright registration, prevents user identity information from being illegally obtained, and has better performance and security.
