This document provides an outline and overview of keystroke dynamics for user authentication. It discusses: - Biometrics like fingerprints and keystroke patterns that can be used for identification - Keystroke dynamics measures latency between keystrokes and duration of key presses - Literature on keystroke authentication systems, classifiers, and factors that affect performance - Approaches like static and dynamic verification, and features like hold time and up-down times - System architecture including enrollment, extraction, preprocessing, storage, and authentication - The document presents results of experiments analyzing EER, accuracy of different features, and comparisons of authentication attempts.
