User authentication system based on keystroke timing in e-learning settings

抄録

Biometrics technology has lately been applied to user authentication systems to achieve high precision. The problem is that such systems require special hardware devices, which results in low installation rates. In our research, the interkeystroke timing of keyboards is adopted as one of the biometric measures. The objective of this paper is to verify the validity of the identification by measuring interkeystroke timings of individual computer users. For better reliability, we decided to use interkeystroke timings of similarly combined alphabets for authentication and further incorporate bi-directional authentication. The evaluation and feasibility of this method are discussed using the results of the experiments. The results suggest that this system is capable of authenticating not only during login but also in the course of general typing (for instance, during e-Learning).
