Investigating & Improving The Reliability And Repeatability Of Keystorke Dynamics Timers

Abstract

One of the most challenging tasks facing the security expert remains the correct authentication of human being which has been crucial to the fabric of our society. The emphasis is now on reliable person identification for computerized devices as the latter forms an integral part of our daily activities. Moreover with increasing geographical mobility of individuals, the identification problem has become more acute. One alternative, to curb down the increasing number of computer related crimes, is through the use of keystroke biometric technology which represents an enhancement to password mechanisms by incorporating typing rhythms in it.Time captured being critical to the performance of the identifier, it is primordial that it satisfies certain requirements at a suitable degree of acceptability This paper presents an evaluation of timing options for keystroke dynamics paying attention to their repeatability and reliability as well as their portability on different systems. In actual passwords schemes users enroll using one computer and access resources using other configurations at different locations without bothering about the different underlying operating systems.

Keystroke dynamics for biometric authentication — A survey

“…Pavaday narainsamy et al [29] evaluated the timing options for keystroke analysis. The user is authenticated depending on the keystrokes captured i.e.…”

A review on the public benchmark databases for static keystroke dynamics

“…Operating System (OS) used. The OS plays a role in the accuracy of the timing capture [31]. This information can be specified (a) with a string giving the OS name (e.g., Ubuntu 13.10), (b) a number symbolising a predefined value in a list of possible OS (e.g., OS#2), or (c) a histogram if each user can launch the experiment on a different OS.…”

“…Clock resolution. It is well known that clock resolution of the method used to capture typing times has a big impact on performances [31,32]. That is why this information is very important to track.…”
