Fingerprints 'not particularly private,' security

Catching on slowly to identity plurality
We should be in the middle of a true paradigm shift, to a new worldview based on a plurality of identities. The Laws of Identity point with great clarity to the reality that we each lay claim to a suite of identities. My own work in PKI over the years (see e.g. Public Key Superstructure) has led to a firm belief in the usefulness of multiple digital certificates, mapping on to multiple real worl identities.
Biometrics
Biometrics is often refered to as "three factor" authentication, referring to the objective of establishing not only what you know and what you have, but also (or instead) what you are.
