@Moon i already thought about the logistics that go in to trying to sign every frame that comes out of a recording device. it would be quite stupid to have to give everything capable of any kind of signal capture some ECC chip to just sit there and sign frames of audio or video as it writes them to disk. then you get in to destructive transforms like compression or editing a video. what for that? does the DAW and NLE have to do some blake tree hashing scheme where it attaches a crypto stream to the edit to attribute that? does nuke have to legally mark that it combined 3 different video streams when you did a composite?

or is it just a more limited thing like "oh well we'll just do it for certain 'evidence' cameras and we'll assume anything heavily edited is known to be faulty"

on top of all that, i'm sure the supply chain would be clowned and the NSA/CIA/Mossad/et all would find a way to cheat it anyway :blobcatdunno:
