Fingerprints also have this issue. You only get ten of them that should last your entire life.
With cooperation, we can build 'revocable biometrics' that mix faces and fingerprints with a password or PIN. To revoke your biometric, simply forget your PIN.
The only thing you can do with these models is verify your claimed identity. They can't be used for search. So they're great for users, but not so great for evil establishments that want to search for terrorists or whatever in large biometrics databases.
- Natanael_L 10y agoThat's basically a hardware token with fingerprint readers. Smartcard versions already exists of that.
- sukilot 10y agoIOW, salt your meat.
- entheon 10y agoUh, no thanks! I'd like to avoid solutions that facilliate an implicit assent to the collection of biometric data. The plan you've outlined still has large organizations building massive libraries of immutable identity data. (they'll still have the fingerprints, however mixed and matched and re-ordered, and they'll still have the scanned faces) At the end of the day, we'd still be letting them, asking them, begging them to store our finger prints and recognize our faces. Putting bald data in the hands of amoral, faceless, collective entities like corporations and governments.
- gcr 10y agoThe work I'm thinking about (revocable biotokens) is a bit like a hash, so Facelesscorp never gets access to your raw biometric. The only thing Facelesscorp can see is an opaque blob that they can only use to verify a cooperative subject's identity; it's not useful for anything else.
