Description
Biometrical authentication systems are gaining prominence and have become increasingly
important to ensure compliance with privacy and safety regulations. In this paper, keystroke dynamics as a
behavioral biometric approach to user authentication is evaluated in terms of the impact that stress may have
on the typing pattern of a user. To achieve this, several experiments were conducted with a group of users
that comprised working users from the industry as well as students. The experiments included stress factors
such as a physical limitation (use of the non-dominant hand to type), a time constraint, and a knowledge
constraint (typing in a foreign language). The results were compared to a baseline (normal circumstances)
typing pattern. Typing data were recorded and analyzed by a keystroke software package called
GenoGraphiX-Log 2.0. The study revealed that stress is indeed a factor in keystroke dynamics and that
typing patterns in some cases significantly differ from the normal typing patterns. This in turn may influence
the efficiency of the use of keystroke dynamics as a biometric authentication system.
