Design And Implementation Of Blockchain-based Management And Marketing System Of Digital Music

With the development of information technology,the way the masses consume music has changed,and people gradually get into the habit of paying for digital music content.However,the Chinese digital music market lacks an open and comprehensive copyright information retrieval database and systematic pricing standards,and the distribution channels for decentralized copyright content are limited.How to improve the management and marketing of digital music to protect the copyright of digital music and reflect the value of digital music copyright is current the focus of industry attention.This article mainly carried out the following work:1)The article analyzes and summarizes the needs of digital music operation management,which consists of that shortening the right confirmation cycle,making the right use process public,and improving the efficiency of rights protection.The article designs and implements of a blockchain-based management and marketing system of digital music(B3M)that integrates copyright registration,transaction and inspection,and solve copyright privacy protection issues,efficiency and integrity issues,and data storage issues during the implementation of the B3 M system.2)Aiming at the problem of copyright privacy protection of digital music in the blockchain-based management and marketing system of digital music,the article design the protection strategy of digital music copyright privacy information based on the We Identity selective disclosure method,and selectively disclose the digital music copyright privacy information.The article analyzes the used strategy and further proposes an improved method for the selective disclosure method.The improved method can reduce 0 to 9)-8)-1encryption operation(9)is the total number of fields in the copyright certificate,and 8)is the number of fields about the privacy information of the copyright certificate).3)Aiming at the efficiency and integrity problems in the blockchain-based management and marketing system of digital music,combined with the We Identity smart contract,the smart contract for management and marketing of digital music is designed.The efficiency of retrieval of copyright deposits on the chain is guaranteed by the introduction of certificate management and the system maintains the pricing standard system by decoupling the pricing logic and tracking updates.In addition,the article protects transaction privacy information by encrypting transaction records,which at the same time increases the credit for transaction authorization certificates.4)Aiming at the data storage problem in the blockchain-based management and marketing system of digital music,the IPFS-based on-chain and off-chain collaborative data storage is realized.According to the requirements of resistance to tampering and transparency of copyright information,the copyright information is stored on the blockchain,and IPFS is used as an alternative to the blockchain to store digital music and copyright vouchers.In addition,the My SQL database is used to persist business data of B3 M system.This article designs and implements of the main function modules of the B3 M system based on the above content.Experiment results show that it takes about 8s for the B3 M system to complete the copyright registration of a piece of digital music,and it takes about7.5s for the IPFS to store the digital music and copyright voucher,which meets the performance expectations.The design of the B3 M system relieves the storage pressure and bandwidth consumption of the alliance chain,and can be applied to a larger-scale alliance chain network than that in the experimental environment of this article.Therefore,the schemes aiming at management and marketing of digital music designed in this article are feasible.
