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?
Well Australia will probably so something privacy invading and fascist.
I guess if you want it to be somewhat private you could have some kind of hash or token generated from your identification information. I bet that would be fairly private
