Abstract:
A method of authenticating user identity, comprising:grasping a stylus as a transaction request is initiated, the stylus enabling a written image to be generated upon a flat surface; capturing a first sensed fingerprint image of a first finger as the first finger is positioned proximate to a first fingerprint image sensor the first fingerprint image sensor being positioned in such a manner that the first sensed fingerprint image is captured as the stylus is touched; comparing the first sensed fingerprint image with a first reference fingerprint image the first reference fingerprint image being captured during a user registration fingerprint image comparison being performed within a matching processor; capturing a second sensed fingerprint image of a second finger as the second finger is positioned proximate to a second fingerprint image sensor, the second fingerprint image sensor being positioned in such a manner that the second sensed fingerprint image is captured as the stylus is touched, and approving the transaction request whenever the matching processor decides that based at least partially upon fingerprint comparison data of the second sensed fingerprint image and the second reference fingerprint image and the first sensed fingerprint image and the first reference fingerprint image, identity is confirmed, confirmation determination being independent of any image generated upon the flat surface.
