SUMMARY
In general terms, the invention disclosed hereby includes in the embodiments thereof, a unique combination of user and host authentication. The security system of the present invention is out-of-band with respect to the host computer and is configured to intercept requests for access. The first step in controlling the incoming access flow is a user authentication provided in response to prompts for a user identification and password. After verification at the security system, the system operating in an out-of-band mode, uses telephone dialup for location authentication and user authentication via a password entered using a telephone keypad.

When voice recognition is employed for the biometric component, the user speaks a given phrase which the system authenticates before permitting access. Upon granting of access, the user now for the first time enters the in-band operating field of the host computer.
