Website: 18+? Gob.: Yep ???

The ideia is neither party is aware of the other’s info. The website wouldn’t have your data, and the gob. wouldn’t know what the information is for.

Website knows, e.g. is the user 18+?, which the user agrees to share, but not anything else

Gob. knows, e.g. you wanted to confirm being 18+ (better if it just didn’t know at all), but knows not what use you’ll make for that

One side asks a yes or no question, the other gets a question (no source), answers it, the answer makes it back to the first side with no further info.

Unless they can know exactly who you are because you proved to be 18+ or something. Granted, if it were your names, for say a social media profile, that’d be different

Hmm… sounds good, other than the amount of work getting and sending stuff everywhere. Though I guess if it were a one-time thing, that’d be fine. I’m used to no cookies and the cookies pop-up always coming back cuz the website never remembers, so my mind just went “too much work” but it could work if the website were to not prompt every time

You’d have to authenticate yourself with the gob., therefore proving your real identity. The gob. would then, for example, provide proof of you being 18+, if that’s what is relevant, without knowing what your use case is, and the website, without getting any further information about you, can then confirm you are indeed 18+ (gob. confirmed). Said confirmation would need to be temporary, to ensure fresh information (akin to 2FA TOTP, which changes after some time)

I didn’t say “log in to porn via gob.”

I was rather proposing a way to privately and securely confirm age without either party (gob. and adult site) knowing each other’s info (i.e. porn site doesn’t get your info, gob. site doesn’t know you’re seeking adult content)

And it isn’t an idea limited to pornography-related websites, but rather any website that wishes to confirm any information about the user, without directly getting the user’s info

It’d be essentially a temporary certificate of sorts that proves a requirement, such as “18+”
