Not sure what you mean by "like europe" because in Europe they are trying to implement `European Digital Identity (EUDI)` for age verification, which will make stuff like this even worse ....

You are not supposed to use EUID for age verification. Instead you use the age verification system.

EUID is made for working with government agencies, banks, etc where you need proper identification of the person and the age verification for verifying ones age (it doesn't even say how old you are just that you are over X years old)

https://ageverification.dev/

End goal is to unify them into the same app at some point but the certificates/validation flows are different. Also as the use cases are very different for the proper identification a whilelist is used on who is allowed to request it. With age verification as it is just a certificate that anyone can validate against the public key so no whitelisting possible (or wanted really)

On the contrary, third parties will only get to know the age of the users, not their identities.

“Linkability is especially problematic because untrusted entities, such as attribute providers and relying parties acting together, can correlate and link auxiliary information to the same user, thereby breaching privacy and enabling tracking, profiling, or de-anonymisation.” [1]

That’s assuming EUDI never gets breached — but if Google and every major tech company has been, it’s only a matter of time, but this will have way more personal info ....

I've been using discord for 5 years and never upload my ID … And I don't want discord (or any other company) to know my age, or any other identification ...

For sure, but with the EU system you'd just give discord an expiring certificate that proves you're over 18. They can leak that all they want, it's worthless otherwise. Right now you have to upload your actual ID which is obviously extremely dangerous if leaked. So yes, even though there are obvious problems that you mentioned, the EU implementation is better.

EUDI requires Google or Apple, I hope it is DOA. It is even bloated before anyone adopted it.

I mean leaked from the EUDI side.

> the EU implementation is better.

It's better than the current implementation, sure, but you can never beat zero identifiers

Again, for sure and I agree with you - but we're talking about institutions that already have our IDs in some form or another, so just asking them to issue a certificate that says "yeah this user is actually over 18" seems like a no brainer functionality on top of an existing system. Like obviously our government office has a copy of my passport and ID card, but if those leak then we have a much bigger problem as a country.

That is not true, EUDI is a security problem instead of a solution. It is trivial to correlate the info and there is a critical path where a breach would expose even more.

Best security: Don't collect. Nothing comes close, no even the best ZK setup.

Also, as a European citizen I really don't want it. Ironically governments aren't mature enough for that.

You must be new here. /s
