Analysis of Keystroke Dynamics Algorithms with Feedforward Neural Networks

Abstract (Summary)

Keystroke dynamics—the analysis of typing rhythms to verify the identity of the person producing the keystrokes—has the potential to improve password-based authentication system by introducing a biometric component that requires no extra hardware cost and provides non-intrusive verification. Various algorithms have been proposed in the literature, and numerous public datasets have attempted to build a body of training data. Despite the availability of public datasets, very few studies have looked at the performance of algorithms across datasets. This study introduces a new algorithm to this domain, a deep neural network, and applies it across two keystroke dynamic datasets. Using the DSL2009 benchmark dataset, we were able to achieve results equivalent to those of existing algorithms, while greatly reducing network size and training time. Using the GREYC dataset and applying the same approach, we were able to achieve an EER of 5.6%, an 18% reduction over the best published methods.
