A remote authentication system for authenticating remotely located users of authenticable communication devices, comprises a device authenticator for obtaining an authenticated device identity, a user authenticator for obtaining a personal biometric measure from voice transmitted from the communication device by the user, and a database of biometric measures and device identities for allowing the personal biometric measure received at the user authenticator to be related via the communication device identity to a prestored personal biometric measure of a legitimate user of the authenticable communication device, thereby to authenticate the user. A preferred biometric measure is a voice print and a preferred communication device is a mobile telephony device, whose device identity or CLI is authenticated upon log-in. Authentications can be user initiated or center initiated and do not require specialized equipment at the point of authentication. |
