I am looking to store and retrieve hashes of authentic audio files on the Ethereum blockchain with the purpose of checking authenticity of these audio files in the future with the hashes stored on the Ethereum blockchain.
But the main concern is that even slightly tempered audio file with regards to bitrarte will provide a different hash and hence will come out as non-authentic. Can I stored multiple hashes of different versions of the authentic audio files on the Ethereum blockchain.
What is the best way to achieve this on the Ethereum blockchain? can a smart contract be used to achieve this use case. What hash function should be used on the audio files that would be suitable for storing in an ethereum smart contract, does it matter if its sha1/sha256.
