In this thesis paper, the comparison between re-authentication and continuous authentication has been performed. Re-authentication is the traditional way to identify users and cannot monitor the user in an ongoing process. This has spawned a new breed of authentication software that monitors the user continuously during the session. The use of multimodal biometric systems in a continuous authentication process, in order to authenticate the user is now a reality. There are two research questions in the thesis: Does continuous authentication provide a feasible solution for identifying computer users in a transmission session? How is system security and usability affected by using a biometric multimodal system during the continuous authentication process? There is a strong need for new technologies to overpass intrinsic limitations of established techniques. It is up to us to determine the real potential and limitations of existing techniques. There is no best way to protect the user¡¯s computer security, but we can always try to improve upon what we have. Security is a process, not a product. Computer security is everyone¡¯s responsibility.
