alt Hacker NewsYou're now arguing about something which isn't even in the proposal from the EU, it's a hypothetical from the article which attempts to draw a parallel with existing physical id (I guess to demonstrate to people that this already happens regularly with passports, ID cards, driving licenses etc).
That existing physical ID is government issued, has an issue no, usually has a photo on it, often other biometrics nowadays, and is definitely traceable!
Absolutely such a proposal cannot be fully privacy preserving, because at the very least it gives away your age, but also probably other identifiers.Just like your browser that you're using right now gives away a lot of information which advertisers use to fingerprint you like fonts etc. This sort of solution requires a central issuer/authority to know about the tokens, there's no way round that as there is no way round governments issuing passports if you want border control.
The goal is that it'll preserve much better privacy than uploading passports etc to random websites, which I think it will.

Yeah. The HN link here is not to the EU proposal. It’s to this dude’s article, which is very clearly what I was responding to.
> I guess to demonstrate to people that this already happens regularly with passports, ID cards, driving licenses etc
No. That’s not what he was doing at all. He very explicitly was not talking about a passport or ID card.
He was describing a physical analog to the digital proposal.

You seem to have completely lost the plot. We aren’t discussing passports. No one is talking about anonymous international travel here.
