An Internet based speech biometric verification system

Abstract

Authentication and privacy are crucial to Internet security due to its increasingly popular as the channel for information exchange, and the storage of sensitive network. In general, public key cryptography is applicable for both purposes but designing a high security authentication and strong privacy protected system still remain an open problem because of the weak usage of the passwords. The alternative options like biometrics are well suite for authentication because it is unique to each individual and cannot be lost, stolen, or recreated. A verification model incorporated with an appropriate algorithm is presented to facilitate on-line speaker verification for the web based access control application. The system allows for both the enrolment session and the actual verification to be done via a website, using a PC at the client side equipped with a multimedia microphone. Verification is performed at the server side to permit or deny the request for access. Initial evaluation of the prototype system is discussed.
