The point is that if someone catches the President shagging kids, of course that footage won't be authenticated by the WH. We need a tool so that a genuine piece of footage of the Pres shagging kids would be authenticated, but a deepfake of the same would not. The WH is not a good arbiter since they are not independent.
Politicians and anyone at deepfake risk wear a digital pendant at all times. Pendant displays continually rotating time-based codes. People record themselves using video hardware which crypto graphically signs output.
Only a law/Big 4 firm can extract video from the official camera (which has a twin for hot swapping).
Codes which don't embedd any information about what you're saying or doing can be copied over to faked images.
In theory you could have such a pendant record your voice, etc, and continously emit signatures for compressed versions of your speech (or a signed speech-to-text transcript)
But we are talking about official WH videos. Start signing those.
If it's not from the WH, it isn't signed. Or perhaps it's signed by whatever media company is behind its production or maybe they've verified the video and its source enough to sign it. So maybe, let's say the Washington Post can publish some compromising video of the President but it still has certain accountability as opposed to some completely random Internet video.
