摘　　要：针对传统音乐版权行业版权确权难、侵权监测难、维权取证难、版税结算难等问题,将区块链技术应用于数字音乐版权管理领域具有重要意义。通过使用VNT Chain区块链平台设计构建了一个数字音乐版权管理系统,在其中利用区块链技术为音乐版权提供存证性证明以及实现证据固化,采用Shazam算法为音乐版权提供原创性证明,并基于智能合约保障交易的安全可靠。所建系统包含用户管理、版权登记、版权交易、侵权监测、证据固化、音乐生态六大功能模块,涵盖了版权管理的主要环节,并根据业务数据的不同需求分别采用区块链、星际文件系统(IPFS)以及MySQL作为存储引擎。实验结果表明,每首音乐的版权登记时间增幅约为1.9 s,平均每首音乐的特征指纹数据存储在IPFS上大约消耗8 MB,符合预期的系统性能要求。It is of great significance to apply the blockchain technology to the field of digital music copyright management in view of the difficulties in copyright confirmation,infringement monitoring,right protection and evidence collection,royalty settlement and other problems in the traditional music copyright industry.A digital music copyright management system was designed and constructed by using the VNT Chain blockchain platform.In the system,the blockchain technology was used to provide the proof of music copyright and realize the evidence solidification,the Shazam algorithm was used to provide the proof of originality for music copyright,and the smart contract was used to guarantee the security and reliability of transactions.This system included six function modules:user management,copyright registration,copyright trading,infringement monitoring,evidence solidification and music ecology,covering the main parts of copyright management.According to different needs of business data,blockchain,InterPlanetary File System(IPFS)and MySQL were adopted as storage engines respectively for the system.Experimental results show that the copyright registration time of each music increases by about 1.9 s,and the storage of music feature fingerprint data of one song on IPFS costs about 8 MB averagely,which meets the expected system performance requirements.
