Digital Music Copyright Protection System Based on Blockchain

With the development of global informatization and digitalization, a large number of digital content works are produced, such as e-books, music, videos and so on. The copyright registration mechanism provided by the traditional third-party copyright management platform can no longer meet the needs of the rapid development trend of digital works. This paper proposes a digital music copyright system based on blockchain. On the Ethereum platform, smart contracts are designed to achieve copyright registration, music authentication and music crowdfunding. Digital signature technology is used to realize the authentication and authorization of transaction information. The Shazam algorithm is used to extract the audio fingerprint. The Interplanetary File System (IPFS) stores the extracted audio fingerprint, and the blockchain stores the hash value generated by IPFS. Compared with the existing system, the function of this system is more perfect. And innovatively through smart contract and digital signature technology, this system realizes the authentication and authorization of transaction information. In particular, it ensures the authenticity of the crowdfunding campaign.
