Biometrics are public keys you can’t throw away or hide. 

That’s why recognizing them can be the basis for tractable and sybil-resistant federated blocking (eg no-fly lists, Face ID).

AI can be trained to recognize these. Only non-AI alt is monopolistic unique identifiers like passports.

- uniqueness (biometric)
- behavior (usage patterns)
- reputation (community-driven)
- location (gps)
