With David Birch We asked the Question. Identity – Authentication – Identification – Authorization and ultimately verification, where are we.
Simple. We have the technology. We have the standards and more are coming. Authenticate, is done, use FIDO.
Identification with Biometrics is illuminatingly possible. Even the one I know how to spoof, Voice, with other factors layered in, does the job very well.
The challenge is Privacy and Confidentiality must be inherent while regulatory practices must be incorporated.
