Remote access control by means of speech

This work deals with remote user identity verification by means of voice. This problem can be separated into two tasks: speaker verification and remote performance of that verification. In this paper we are concerned with the last one, considering two main problems in it: data security and multiple access points. The proposed approach is a client-server distributed system, that solves two different situations: local access-remote verification (e.g., the "door" of a restricted area is managed by a remote system), and remote access and verification (e.g., bank operations by telephone or computer). We are concerned with open systems, so we use standard TCP/IP communication protocol, making it easier the integration of our verification system with other control systems.
