Abstract: An apparatus for collecting information directly at a point on a surface comprises the combination of a stylus with means for sensing force along at least one axis in a surface at a point on the surface and a position sensing platen or pad with means for sensing a true position along at least one axis on the surface at the point in question. Collected information is processed to obtain figures of merit. Features extraction or rubbery correlation in five dimensions may be employed to obtain suitable figures of merit for objective evaluation.

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.
