Many might’ve seen the Australian ban of social media for <16 y.o with no idea of how to implement it. There have been mentions of “double blind age verification”, but I can’t find any information on it.
Out of curiosity, how would you implement this with privacy in mind if you really had to?
No! Because it leaked everything but the birth date to the verification party.
I’ve always thought that it should be the relevant ID issuing organisation, with whom the damage to privacy has already been done, might as well leverage it.
