I'm more interested in how exactly you'd implement something like this.
It's not like videos viewed on tiktok display a hash for the file you're viewing; and users wouldn't look at that data anyway, especially those that would be swayed by a deep fake...
Likely it would be a service provided by the Whitehouse press corps and media outlets then could rehost the videos with the whitehouse watermark
I've always thought that bank statements should require cryptographic signatures for ledger balances. Same with individual financial transactions, especially customer payments.
Without this we're pretty much at the mercy of trust with banks and payment card providers.
I imagine there's a lot of integrity requirements for financial transactions on the back end, but the consumer has no positive proof except easily forged statements.
Yeah but that would require banks to actually invest money to improve customer trust... Not something banks are very interested in, really. It's easier and cheaper to just have the marketing department come up with some nonsense claim and advertise that instead.
