A multichannel security system is disclosed, which system is for granting and denying access to a host computer in response to a demand from an access-seeking individual and computer. The access-seeker has a peripheral device operative within an authentication channel to communicate with the security system. The access-seeker initially presents identification and password data over an access channel which is intercepted and transmitted to the security computer. The security computer then communicates with the access-seeker. A biometric analyzer—a voice or fingerprint recognition device—operates upon instructions from the authentication program to analyze the monitored parameter of the individual. In the security computer, a comparator matches the biometric sample with stored data, and, upon obtaining a match, provides authentication. The security computer instructs the host computer to grant access and communicates the same to the access-seeker, whereupon access is initiated over the access channel.
