To be clear, I’m not advocating for online age verification. I’m very much against it in any form. I’m just curious from a technical standpoint if it’s possible somehow to construct an accurate age verification system that doesn’t compromise a user’s privacy? i.e., it doesn’t expose the person’s identity to anyone nor leaves behind a paper trail that can be traced to that person?
This is possible if there’s a central authority for that that everyone can agree to trust, like the government records directly. The issue is ensuring the rest of the chain remains anonymous so the only thing the authority gets is the request that an undisclosed service is verifying John Doe is 18+ and nothing else. And that’s not something many governments are going to want to allow with the increasingly alarming amount of authoritarian leadership.
