Do you have an idea how could such a database of copyrighted material be shared? (Asking for a friend...)

I think that it'd be enough to store some kind of fingerprints (eg. selected frequency components after performing the FFT), not the whole samples.

Indeed it seems to be the best option.

Good point. Perhaps use only parts of the material (not the entire clips). This should be covered by "fair use".

And perhaps using the clips for other purposes than "viewing" may in fact be fair use. Especially since you are trying to find a method for not viewing them.

(IANAL)

IANAL as well, but this notion of "fair use" seems slippy. I had a look in the French article that lists some exceptions that allow sharing copyrighted material, and did not find any obvious match with the potential shared database.

I was under the impression that for purposes of research, fair use is pretty broad. So perhaps you could explore that angle.

Just apply a transform to them like FFT then it's not the original work anymore and it should be fine.

You know MP3 is kinda like a FFT right?

Yeah, but if you lose enough info such that it doesn't play like the original or can't be reconstituted into the original it's still large enough of a change that it should steer clear from copyright issues. No one's really tested exactly where the distinction falls.

Agreed
