Abstract: Apparatus and methods are described for pressing and releasing keys and measuring timing data of the key presses and releases of a keyboard input device to determine characteristics of different types of keyboards. A key of the keyboard may be pressed and released by a machine at measured speed; and resulting keystroke timing data may be collected from to identify timing delays and differences in delays between when the key is pressed and when the resulting timing data is collected by a computer. The timing delays and differences in delays may be used generate more accurate biometric templates and authentication inputs when a type of keyboard is used.
