Stumbled across this interesting webcast. I have discussed self-service password reset solutions numerous times with customers. This is an interesting new method using the phone system and your voice.
To see the webcast, you have to start here (incredible long URL). Most solutions are based on answers to enrolled questions, but VOICE.TRUST is using the voice itself as biometric! The VOICE.TRUST is the worst presentation - but the most interesting product.
To the techies: Do not ignore it just because it is a level 200 session.
