Abstract: This paper proposes an audio copyright certificate model based on blockchain storage,which makes the audio works uniquely and can be stored on the blockchain that cannot be tampered with,without the need for an additional copyright agency.Although the audio fingerprint that uniquely identifies a piece of audio can partially solve problems such as piracy in copyright certificates,the support of a centralized platform is still needed to eliminate piracy,then copyright protection still has problems such as inefficiency,opacity,and untrustworthiness.Here a "audio fingerprint+blockchain" solution is proposed,to prevent copyright theft from the copyright registration portal,to provide a technical basis for the establishment of a digital copyright trading platform and the resolution of opaque copyright information.The model is based on the intangible advantage of the blockchain,which can not be tampered and traceable.The generated audio fingerprint is compressed and split,added with timestamp,and signed by the user's private key to construct a basic work release certificate,which is sent to each node of blockchain.Each node performs signature verification,packages into the block,and completes the deposit.

Key words: Audio fingerprint, Blockchain, Copyright deposit, Non-tamperable
