I know the EU is still kicking around the concept of making itself a root CA and each country an intermediate in that chain, then legally mandating the installation of that CA on all devices. This is dangerous as hell as it effectively defeats the purpose of TLS and gives the government(s) a way to decrypt all HTTPS traffic using those bogus cert chains.
You either can tell that the same certificate was used 1000000 times in one day which means they are being tracked or you don't track it and one leaked cert can be used by all the minors in Spain. So it's either useless of bad for privacy.
It is the parents job to watch their damn kids. Or force isps to include simple blocklist toggles in their supplied routers so the parents can make a decision.
Looks like another govt relying on majority that has no idea about how internet works. It won't stop kids, but pr0n sites and their partners will certainly get richer.
The whole age verification can be done privately, secure and without the possibility to get tracked. But imho still not really a good thing to do. Parenting should still be a thing.
Thank you for the links to Wikipedia and identity.com on that other thread. I've yet to wrap my head around how zero-knowledge proof could work for such a basic assertion as "user is of legal age", which calls for a 0 or 1 answer. It seems very different from the examples given of polynomial computations to prove knowledge of an exponent in a complex math expression. I can't see what could prevent any client to simply lie about the answer here.
But that refers to personal data, and I suppose the state will be able to identify you and your habits if it gets the logs from the websites.
I wonder if the websites will get a unique identifier, that would allow them to track you so accurately it would make google horny.
