Personal authentication system, apparatus and method

A remote authentication system for authenticating remotely located users of identifiable devices, comprising:

• a device authenticator for obtaining an identity of a user associated device,
• a user authenticator for obtaining a personal biometric measure from voice transmitted via a communication device by said user,
• a database of biometric measures and device identities for allowing the personal biometric measure received at the user authenticator to be related via the device identity to a prestored personal biometric measure of a legitimate user of said user associated device, thereby to authenticate said user, and
• an authentication output for producing a verifiable signal to indicate successful authentication.

A method of remote authentication of a user, comprising:

• obtaining an identity of an identifiable device,
• obtaining from a database an identity of a user associated with said identifiable device,
• remotely obtaining from said user a biometric measure,
• comparing said obtained biometric measure with a prestored biometric measure of said associated user,
• authenticating said users if said biometric measures match, and
• producing a verifiable signal to indicate successful authentication.
