KeyStroke Dynamics - Dangling Issues of Providing Authentication by Recognising User Input

D. Ramya Krishna, D. Koteswaramma


A behavioral biometric such as keystroke dynamics which makes use of the typing cadence of an Individual can be used to strengthen existing security techniques effectively and cheaply. Due to the ballistic (semi-autonomous) nature of the typing behavior it is difficult to impersonate, making it useful as a biometric. Therefore in this paper, we provide a basic background of the behavioural basis behind the use of keystroke dynamics. We also discuss the data acquisition methods, approaches and the performance of the methods used by researchers on standard computer keyboards. In this survey, we find that the use and acceptance of this biometric could be increased by development of standardized databases, assignment of nomenclature for features, development of common data interchange formats, establishment of protocols for evaluating methods, and resolution of privacy issues.

Keywords: Authentication, Behavioural biometrics, Identification, keystroke dynamics, typing.
