MBE: A Music Copyright Depository Framework Incorporating Blockchain and Edge Computing.

Audio copyright is a crucial issue in the music industry, as it protects the rights and interests of creators and distributors. This paper studies the current situation of digital music copyright certification and proposes a music copyright certification framework based on "blockchain + edge computing mode," abbreviated as MBE, by integrating edge computing into the Hyperledger Fabric system. MBE framework compresses and splits the audio into small chunks, performs Fast Fourier Transform (FFT) to extract the peak points of each frequency and combines them to obtain unique audio fingerprint information. After being confirmed by various nodes on the Fabric alliance chain, audio fingerprint information and copyright owner information are recorded on the chain and broadcast to all participants. Blockchain technology's characteristics of being tamper-proof and traceable not only reform the trust mechanism of copyright protection but also endow edge computing with the ability to resist tampering and single-point attack, greatly enhancing the robustness of the music copyright certification system. Meanwhile, edge computing mode improves Fabric blockchain's processing speed and transaction throughput. Experimental results show that MBE's performance is better than traditional systems regarding efficiency, storage demand and security. Compared to the traditional Fabric system without edge computingmode,MBE exhibits a 53% higher deposition efficiency and a 48% lower storage space requirement. [ABSTRACT FROM AUTHOR]
