Abstract or Summary:
This article presents a methodology for the reinforcement of password authentication through typing biometrical mechanisms. Typing biometrics is the analysis of the keystroke patterns unique to each user. This analysis is transparent-indiscernible to users-while they are trying to gain system access via a password-authentication mechanism in the normal way (by entering a user ID and password string). The analysis employs fuzzy logic, which has great potential to categorize each user's typing patterns. The integration of fuzzy logic-based typing biometrics with current password mechanisms, which constitute the most universal authentication device, can greatly enhance security.
