Like what though? Historically what tech does did governments have that was unknown to commercial domains? People are motivated by money, governments pay little and there’s no way to get rich working there so it doesn’t make that much sense.

Around WWII Computers, Radar, Nuclear power, crypto, jet aircraft, rockets. Around 1960 space flight, supersonic flight. More recently hypersonic flight, and we don’t really know becase people back in WWII had no idea.

True but now all that stuff is pretty much produced in the private sector by government contracts with these big companies. DARPA doesn’t have better scientists than MIT and there are a lot of extremely intelligent scientists who have moral issues about working for the military.

Is there a way that a person could create a QR code made from one-way private key? The QR code would contain date and time and other Metadata that is decrypted with a public key that proved the QR code in the video was made by, for example, the person in the video? This would "prove" the video was real? I guess the speech would still be manipulated. So the whole transcript would have to be encrypted in this way...

Some applications for this kind of tech: - Porn, yeah, first application you can think of, there are already some startups doing it. - Doubling actors, and applied to sound, maybe you could translate from one language to another but kind of keeping the accent and tone. - Propaganda and misinformation. Now you can get your enemy to say and do whatever you want, on video. - Photo-realistic games. Create a rough 3D mode…

any ideas about porn startups that work on anything related to this? i know pornhub and their network banned deepfakes and there’s also some work being done on detecting deepfakes.

I don't know why you're talking about QR codes and transcripting/encrypting the audio when you can just sign the file?

    gpg --sign video.mp4

I'm curious what would happen if somebody tried to impersonate the US president using this. He would say it's fake, but who would believe him? How exactly can computer scientists explain deepfakes to laymen?

An example of Obama. https://www.youtube.com/watch?v=cQ54GDm1eL0

Also, map images pulled from facebook to the bodies of pornstars. The creepiness and invasion of ... personal image(?) this enables is horrifying.

That's already happened. Search for deep fakes. We already have face substitution in videos which is working surprisingly well sometimes. There's been r/deepfakes where around 30% of the content was porn with swapped faces. It was banned though.

This could open the market for video propaganda-detector applications.

I'm probably being captain obvious here, but if this is what's being released for free, I wonder how much better a polished commercial version does, and when we reach the point where we can't trust anything we see anymore. It doesn't even have to be super perfect, even reaching the point where it takes experts about two weeks to determine if something's real or not might already be long enough to do great damage. Fro…

Isn’t this something a lookalike and some good make up could already do for ages?

I assume they are talking about signing/watermarking a video in a way that survives video encoding/lossy transmission. A QR code probably wouldn’t work for various reasons but is an easy mental analogy to think of.

Chances are there would be corroborating evidence to the contrary, since it's not often the President does or says anything without multiple witnesses and cameras being involved. In that case, it might be easier to impersonate them through their social media accounts.

The real danger here, if anything, is impersonating common citizens or lower ranking government officials.
