Abstract
A device and method for verifying the identity of an individual based on keystroke dynamics comprising a keyboard for the inputting of data in the form of alphanumeric characters by keystrokes, a timing encoder coupled to the keyboard for timing periods between keystrokes, a CPU coupled to RAM and to the timing encoder for generating a template for the individual, the template comprising a first plurality of features based upon a first set of time periods between keystrokes from a first set of keystrokes of the individual and the CPU determining a plurality of extracted features based upon a second set of time periods from a second set of keystrokes, and comparing the template to the plurality of extracted features such that the identity of the individual may be verified.
