Homomorphic encryption, and trusted third parties. Nobody needs to know where you're going, only that you are there.
Probably too complex for casual use. One could imagine a kerberos like "time limited proof" which certifies you for a window.
What you have is who you are is in 2FA so issuing people with 2fa and then interacting through the 2fa.
For sufficient corruption, the TTP flips so it's not foolproof.
- consumer451 2y agoThanks for replying as someone who is familiar with cryptography. Did you ever check out Sam Altman's WorldCoin orb? They had smart folks working on that, no matter the public response. Did you understand how that worked, given the biometric data + ? I believe that they were trying to address my OP problem, to allow UBI. But, did it make cryptographic sense?
- ggm 2y agoNo, never looked at it. It's eyeball scanning, don't know anything about how they tie it into a provable object or what the credential checks are. I believe there was a bit of hype about it in the emerging economies of Africa. I'm not a cryptographer.

Now that I think about it, iPhone also has a biometric component. Maybe I should not have written off WorldCoin as quickly as I did. Please see the thread here.
