If AI and deep fakes can listen to a video or audio of a person and then are able to successfully reproduce such person, what does this entail for trials?
It used to be that recording audio or video would give strong information which often would weigh more than witnesses, but soon enough perfect forgery could enter the courtroom just as it’s doing in social media (where you’re not sworn to tell the truth, though the consequences are real)
I know fake information is a problem everywhere, but I started wondering what will happen when it creeps in testimonies.
How will we defend ourselves, while still using real videos or audios as proof? Or are we just doomed?
Well as I said, I think there’s a collection of things we already use for judging what’s true, this would just be one more tool.
A cryptographic signature (in the original sense, not just the Bitcoin sense) means that only someone who possesses a certain digital key is able to sign something. In the case of a digitally signed photo, it verifies “hey I, key holder, am signing this file”. And if the file is edited, the signed document won’t match the tampered version.
Is it possible someone could hack and steal such a key? Yes. We see this with certificates for websites, where some bad actor is able to impersonate a trusted website. (And of course when NFT holders get their apes stolen)
But if something like that happened it’s a cause for investigation, and it leaves a trail which authorities could look into. Not perfect, but right now there’s not even a starting point for “did this image come from somewhere real?”
