In this paper, the authors describe the theory, architecture, implementation, and performance of a bio-metric verification system that continually verifies the presence/participation of a logged-in user. To achieve robustness they have implemented the concept of 2-Factor Authentication, i.e. using the combination of biometrics (something the users are) and text-password (something the users know) for authenticating users. During the enrolment phase the user has to register with their name, password and finger-print. The finger-print and the text-password are stored against the user's name in the database. Continuous verification is achieved using a finger print scanner.
