摘要:

在当前数字化、网络化时代中,数字版权交易需求越来越大,传统的中心化版权保护系统存在注册成本高、作品受理时间长、容易遭受破坏者的篡改等问题。区块链技术作为一个以P2P网络为基础,以密码技术为核心的去中心化网络结构,能够在网络上以纯数学方法建立信任关系,无需依托中间平台就能够缓解上述问题。借助区块链技术的自我监管、可追溯、去中心化的特性,结合数字版权交易场景,设计了一个基于联盟链的数字版权交易系统模型,利用当前 IBM 提供的最新联盟链技术,做了版权注册和版权交易的实现,能够保证版权信息不可篡改性和可溯源性。最后,测试了链码部署安装时间。结果表明,系统安装简单,维护成本低。相比传统的基于可信第三方版权认证机制,基于区块链的数字版权交易系统注册时间短,无需注册费,具有更好的架构安全性和可扩展性。

Abstract:

In the current era of digitalization and networking,the demand for digital copyright transactions is increasing.The traditional centralized copyright protection system has series of problems such as high registration costs,long work acceptance times,and being vulnerable to tampering by saboteurs.Blockchain as a decentralized network structure and based on P2P network and cryptographic technology,which can establish trust relationship on the network by pure mathematics.Without relying on the middle platform,blockchain technology can naturally alleviate the above problems.With the help of self-regulatory,traceable and decentralized features of blockchain technology and digital copyright trading scenarios,a digital copyright trading system model was designed.The new system is based on the advanced permissioned blockchain provided by IBM.The implementation of copyright registration and copyright transaction can ensure the integrity and tamper-resistant of the information.Finally,the installation time of chain code deployment was tested.The results show that the system is simple to install and has low maintenance costs.Compared with the traditional trusted third party copyright authentication mechanism,the blockchain-based digital rights trading system has a short registration time,no registration fee,and better architecture security and scalability.

Key words: digital rights trading, blockchain, superbooks, system design and implementation
