Report: A voice password system for access security

A voice password system for access security using speaker verification technology has been designed for use over dial-up telephone lines. The voice password system (VPS) can provide secure access to telephone networks, computers, rooms, and buildings. It also has application in office automation systems, electronic funds transfer, and “smart cards” (interactive computers embedded in credit-card-sized packages). As increasing attention is focused on access security in the public, private, and government sectors, the voice password system (Figure 1) can provide a timely solution to the security dilemma.
