how exactly does age verification prevent any of this?
Devil's advocate: couldn't this be better for privacy than other age checks because it doesn't require actual identification?
My bank has an API endpoint that (basically) returns your name and age (in this use case). It can return more for signing electronic docs etc. and is basically your digital ID.https://en.wikipedia.org/wiki/BankIDNeed to buy "toys", vape products, alcohol... anything adult online?There's a 3rd party web app (you rightfully don't trust) as an age check in the shopp
Age verification would probably require some form of ID, killing the site.
It is possible to do an age verification system with the following properties:1. The site that wants to verify your age learns that your age meets their criteria but does not learn anything else from the verification system except as noted in #2.2. The site that you present ID information to in order to prove your age does not learn what site the verification is for. The site in #1 will learn what site you presented ID to but not when you presented it.3. Someone who obtains all the reco
how applicable this will be for the age-verification stuff that's now popping up for social media too?
This feels like it could be resolved by technology.I am happy to identify myself to government entity A to prove my age, but I don't want A to know what sites I visit.I want to visit site B, but I don't want to identify myself.Is there no API that will allow B to verify my age via A, without A finding out what site B is, and without B finding out anything more than my age bracket?

Age verification in a way that is both robust and privacy respecting is an impossibility.Pick one.
It sounds like you are envisioning age verification that involves just two parties: the user and the site that they need to prove their age to. The user shows the site their government issued ID and the site uses the information on the ID to verify the age.That would indeed allow the site to compile a database of government issues IDs and give that information (willfully or via leaks) to third parties.Those issues can be fixed by using a three party system. The parties are the user, the si
