Password-free network security through joint use of audio and video

Abstract

Remote authentication is vital for many network based applications. As the number of such applications increases, user friendliness of the authentication process, particularly as it relates to password management, becomes as important as its reliability. The multimedia capabilities of the modern terminal equipment can provide the basis for a dependable and easy to use authentication system which does not require the user to memorize passwords. This paper outlines our implementation of an authentication system based on the joint use of the speech and facial video of a user. Our implementation shows that the voice and the video of the associated lip movements, when used together, can be very effective for password free authentication.
