This is precisely why the authority doing these checks needs to be the government that already issues the IDs.

Using ZKP as the EU proposes is the only way to prevent this data being leaked to unreliable third parties and leaves the knowledge with the institution it derives from in the first place.

I don't know why HN rails against it constantly, it is the obvious technical and organizational solution to this issue.

Government systems leak information all the time. The type of institution managing the data makes little difference. Its how the institution manages the data that matters.

But the government inherently has that data, as it comes from there. They're the ones issuing the IDs in the first place.

Theres no avoiding this, structurally. So the best thing you can do is not to introduce any additional points of failure.

All previous systems avoided this. The government issued me an ID in the past, yet had no record of when I used it, or for what.

I am so much more afraid of monopolies invading my privacy than roving hackers, or my corner store. Governments are the ultimate monopoly.

		The government doesn't know what you use your ID for in a properly implemented ZKP system, either. And clearly, the alternative is not the corner store. It's private monopolies building databases of 153M IDs.

It is European which means that it is both anti-capitalist and communist and therefore must be spit upon.
