1. A digital user authentication device to authenticate an authorized user, the device comprising:
a wearable user authentication interface to be worn by the authorized user and operable to receive as input, via an authorized user finger contact, unique user identification data required to execute a digital user authentication process, wherein said wearable user authentication interface is operable to capture a user finger image via said authorized user finger contact as input for said unique user identification data;
a distinct physiological sensor operable to interface with the authorized user via a same user finger contact and a distinct physiological interface formed at a distinct wearable user contact location, to simultaneously acquire, via said same user finger contact and said distinct physiological interface upon the device being worn by said authorized user, a physiological signal comprising a time-variable waveform from the authorized user to automatically confirm a live user presence during said user authentication process; and
a digital data processor and computer-readable memory operable to execute computer-readable instructions to invoke said user authentication process based on said unique user identification data while confirming said live user presence based on said physiological signal such that a successful user authentication is only concluded upon confirmation of said live user presence during said authentication process, wherein said digital data processor and computer-readable memory are further operable to invoke comparison of said time-variable waveform with a generic non-user-specific physiological signal profile to confirm said live user presence irrespective of user identity upon said time-variable waveform matching said generic non-user-specific physiological signal profile and denying said live user presence upon said comparison automatically determining that said time-variable waveform is attenuated or corrupted relative to said generic non-user-specific physiological signal profile.
