Keystroke Dynamics: Concepts, Techniques, and Applications

Reliably identifying and authenticating users remains integral to computer system security. Various novel authentication tenchniques such as biometric authentication systems have been devised in recent years. This paper surveys keystroke-based authentication systems and their applications such as continuous authentication. Keystroke dynamics promises to be non-intrusive and cost-effective as no addition hardware is required other than a keyboard. This survey can be a reference for researchers working on keystroke dynamics.
