@aubrey @soderling They can save it, it's pointless, it's just a valid age verification token. The critical point is the authentication system that by law and governance, would be made in a way where you only authorise an age verification not sharing private data with the digital service OR logging on the government side what site you're trying to use. There are more technical steps available for privacy like key pairs, blockchain, owning your data I would prefer first but it is possible.

@soderling No, it is not. Any digital service could query a digital gov ID just for age verification (yes/no signed key) and nothing else is stored in either side. A government audit can run on all users just to make sure they have those signed keys WITHOUT knowing who they are.

@Tutanota Just a note. Age verification is not mutually exclusive to everything that is on the safer column. If the real world has age requirements in some operations, it's acceptable that the digital world also has the same. Making the Internet lawless is what drives attacks on other liberties.
