This is a thing I've started at pretty hard. Embedding a signal that survives basic postprocessing isn't that hard, but doing it in such a way that it stays well below the noise floor and survives extensive editing is not easy. If anyone is interested I could be convinced to put my work on GitHub, highly doubtful that it will go commercial unless I get a huge raft of free time.
- NoZebra120vClip 4y agoAre you saying that a cryptographic signature could survive postprocessing? Well, it may, but when you post-process a sound clip, that sound changes itself. I mean, imagine playing cutups with a dialogue track; that actor may or may not want to attest that the final result is theirs. That's the whole thing. If you cut out three words of dialogue, it is no longer cryptographically signed.
