What this might usher in is the era of cryptographically signed news articles. Not just credibility but verifiability. Blocking
Actually, how about cryptographically signing videos as they get written on the recording device?
Maybe there even are ways to sign data so that the integrity can get validated on shorter segments, so that clips can be cut. Write a signature every 5 seconds for the past 5 seconds?
Edit: This exists and the term for it is 'video authentication'.
That wouldn't prove much besides that the person sharing the video had access to the device's private key. I think the best you can do is timestamp the video by uploading a hash of it to a blockchain, but even then that only proves the video existed sometime before that instant.
Huh, I'd never even considered that you could do that.
- a fact that has been distorted to be interpreted in a 180 degree way (Americans paying tariffs to the US Gov for buying Chinese goods = Trump saying "China is finally paying us!"), or
- a total untruth slipped in between valid concerns (like the fake Russian Black Lives Matter pages piggybacking off of civil rights abuses mentioned by the American Black Lives Matters campaigns), or just
- incitement of uncertainty in more or less solved problem domains (anti-vaxxers)
