Keystroke security dynamics from custom Perl algorithms
Author: JT Smith
Measure the total time of entry and verify the time between keystrokes to help authenticate a user regardless of the data being entered. Learn how to apply the open source tools xev and Perl in keystroke dynamics to measure the more-subtle characteristics of human-computer interaction. This article uses example code to demonstrate keystroke dynamics for enhancing the security of your applications in authentication and continuous data entry contexts.
