Kids can still just use a VPN to get around this, but at least it doesn’t compromise the security of adults.
And I can just sell my “you’re over 18” paper to some kid and he can use it. Spanish government proposed anonymous age verification certs some time ago. It’s also better solution than letting privet companies handle the verification but it doesn’t really solve anything. One leaked cert can be used by all the kids in Spain. If it’s truly anonymous you will never know who leaked it. If it’s not anonymous then… you know.
Well, I can also give my younger brother my ID to sign up to a site he shouldn’t be allowed to. It’s not perfect either. The advantage of this method, is that my digital ID that generates the certs can require authentication (e.g. a pin, or biometric) and sign a single cert which is valid for a single instance (this minute of this day) for a single site. It’s still anonymous, since this can be signed client side, but it can’t be abused.
If someone maliciously leaks their own certificate, and people start using third party software to sign stuff, that’s pretty dangerous, as your cert can be used to sign stuff with your ID attached as well if you want, meaning people could impersonate you for a lot of things, so you’d be pretty dumb to do that, and should report to the police that your ID has been compromised and get a new one issued.
