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.”

Maybe the White House should create a hash of the video and add it to a public blockchain. Anyone can then verify if the video is authentic.
Don’t need to involve a blockchain to make cryptographically provable authenticity. Just a digital signature.
The only thing a hash in a blockchain would add is proof the video existed at the time the hash was added to the blockchain. I can think of cases where that would be beneficial too, but it wouldn’t make sense to put a hash of every video on a public blockchain.
Transparency logs like that are helpful to show when media was first seen / published
Blockchain is the opposite of what you want for this problem, I’m not sure why people bring this up now. People need to take an introductory cryptography course before saying to use blockchain everywhere.
There are many unnecessary steps in that.
Guys, it doesn’t need to be on a block chain. Asymmetric key cryptography is enought to verify authenticity.
