Keystroke Dynamics on a Device with Touch Screen

Type: dissertation
Abstract: Keystroke Dynamics has been heavily researched over many years. Despite the large activity there\nare few real world implementations using Keystroke Dynamics as an authentication mechanism.\nThe change in how internet banks are accessed, from using personal computers to using smart\nphones, in combination with the increasing burden for people to remember many passwords, has\nincreased the need for stronger or enhanced authentication mechanisms.\nWe look at the suitability of using keystroke dynamics as an additional feature to enhance\nsecurity of authentication, when using a smart phone having a touch screen as input method.\nBoth performance issues and security issues are investigated. We are going in depth on keystroke\ndata analysis, where we look at why some methods perform better than others. The change in\nsecurity, as a result of change in the physical/environmental factors are also addressed.\nThe results show that keystroke dynamics on a smart phone are more resilient against certain\nattacks than keystroke dynamics on a personal computer. We proved this by building a device\ncapable of imitate someone’s typing characteristics, and explained why the same task is difficult\nagainst keystroke dynamics on a smart phone. Further, we got good results from using new\nfeatures available from a touch screen, and we also improved the performance of some detectors\nusing a technique that adapts the standard deviation to skewed distributions.
