The secret word is out and crypto is in as government and commercial experts lay the groundwork for the next generation of identity proving and authentication. Passwords are being abandoned in favor of a range of new methods that are more secure and, in some cases, more user friendly.
Biometrics are just part of the solution. They have been paired with public key cryptography in preliminary efforts. Ultimately, the solution may emerge from an entirely new concept of identity that applies across a broad spectrum of applications.
