Abstract

Abstract:In webapplications, user authentication is normally based on username and password,come forth biometric solutions allow biometric data during sessionestablishment. But in Unimodal biometric approaches only use a singleverification is considered and the identity of the user is permanent during theentire session. A secure protocol is defined for constant authenticationthrough continuous user verification. Biometric techniques suggest solution forsecure, trusted and protected authentication. In between the logging sessiontime, the one-time-password (OTP) is send on users registered email id and alsorandomly one questions will be asked to the user between the 5-10 mints. Theuser’s identity has been verified, the system resources are available for fixedperiod of time and identity of the user is constant during entire session. Theproposed system detects misuses of computer resources and prevents maliciousactivities based on multi-modal biometric continuous authentication. Biometricand user information’s are stored in smart phones and web services
