We already have e-passports and zero knowledge proofs to show you have one without revealing who you are.
If all else fails, there is always the web of trust (i think web of trust has a lot of issues, but establishing soneone is human seems like a much lower bar than establishing identity)
Web of trust would be interesting if phones could automatically trust other phones they spend enough time nearby.
I hadn't though of zero-knowledge proofs. That is an interesting idea.
The blockchain people have been experimenting with it https://ethresear.ch/t/zero-knowledge-proofs-of-identity-usi... (im no fan of blockchain but i assume you can reuse the ideas without the blockchain part)
