Doesn’t this assume the issuing agency has all employees who are morally sound and not leaking data, unnoticed by an internally badly designed system, which is designed by people who are out of touch? Most things like this are designed that way, irregardless of country .
I’m sure one can make it watertight but it’s so hard and still depends in trusting people. The conversation here is about one thing of a larger system. There are probably a hundred moving parts in any bureaucracy.
I don’t know anything about cryptology; I have an imagination about how many things can go wrong hooking up parts and running them.
If it’s the law to make an age verification system then it will be made.
But I think one either has an age verification or privacy, but not both, in any country in the world.
I’m totally sure many of the discussions here about crypto are way above my head. But I’m equally sure while any one part will look fine in paper, the sum total will be used by an expanding government agency, crime, or both.
