Here's a free business idea:
Perhaps we need tamper proof authenticated cameras in all major cities worldwide that publish a livestream 24/7 and you can then stand in front of them to prove your human existance...
This could be something that notaries around the world could offer as a service.
Today, we proudly announce, the Meta Rayban 365
Or in general, a way to digitally sign a tamper-free video recoding made with a camera from a reputable manufacturer. Maybe a regular iPhone already has enough integrity checks and security contexts to achieve this.
We used to have something similar in NZ. Got removed eventually because of flashing.
I heard that in France, they'd use postal office workers to verify people's IDs. It's a brilliant alternative to whatever we're doing in Germany.
