Keystroke dynamics
open-in-new
<p>Keystroke dynamics, keystroke biometrics, typing dynamics, or typing biometrics refer to the collection of <a href="/facts/Biometrics/MgTbyA0r">biometric</a> information generated by key-press-related events that occur when a user <a href="/facts/Typing/HyjnNen9">types</a> on a <a href="/facts/Computer_keyboard/MczF9LIS">keyboard</a>. Use of patterns in key operation to identify operators predates modern computing, and has been proposed as an <a href="/facts/Authentication/64y4S69b">authentication</a> alternative to <a href="/facts/Passwords/WEoul230">passwords</a> and <a href="/facts/Personal_identification_number/DGMvGdJf">PIN</a> numbers. </p>
