主 题：Blockchain copyright protection audio fingerprinting smart contracts
摘 要：Audio copyright is a crucial issue in the music industry,as it protects the rights and interests of creators and *** 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 *** 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 *** 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 *** 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 ***,edge computing mode improves Fabric blockchain’s processing speed and transaction *** results show that MBE’s performance is better than traditional systems regarding efficiency,storage demand and *** to the traditional Fabric system without edge computing mode,MBE exhibits a 53%higher deposition efficiency and a 48%lower storage space requirement.
