Abstract
Biometric authentication and touch differentiation embodiments are described which use a handheld mobile computing device having a signal injection site that injects a signal into a user's hand for a prescribed period of time, and at least one signal sensing site each of which captures a signal emanating from a finger of either of the user's hands that is touching the signal sensing site during at least the period of time the signal is injected. The captured signal or signals are analyzed to determine whether they match, to a prescribed degree, a pre-established signal model that is indicative of a signal or signals expected to be captured. The signal matching determination can be employed to authenticate a user, or identify which finger of a user's hand is touching the computing device.
