The White House wants to 'cryptographically verify' videos of Joe Biden so viewers don't mistake them for AI deepfakes::Biden's AI advisor Ben Buchanan said a method of clearly verifying White House releases is "in the works."

you don’t even need to cryptographically verify in that case because you already have a trusted authority: the whitehouse… of the video is on the whitehouse website, it’s trusted with no cryptography needed

the technical solutions only come into play when you’re trying to modify the video and still accurately show that it’s sourced from something verifiable

heck you could even have a standard where if a video adds a signature to itself, editing software will add the signature of the original, a canonical immutable link to the file, and timestamps for any cuts to the video… that way you (and by you i mean anyone; likely hidden from the user) can load up a video and be able to link to the canonical version to verify

in this case, verification using ML would actually be much easier because you (servers) just download the canonical video, cut it as per the metadata, and compare what’s there to what’s in the current video
