Claim:
1. A method for biometric identity confirmation of a subject having a pulse and a respiratory cycle, said method comprising: during an initial training mode, simultaneously acquiring pulse wave shape data and spirometric data from a known subject; generating and storing subject characterization data for the known subject derived at least in part from both the pulse wave shape data and spirometric data for the known subject by: (a) computing an exemplar from the pulse wave shape data and spirometric data for the known subject during the initial training mode; and (b) selectively weighting portions of the exemplar; and during a subsequent identity authentication mode, simultaneously acquiring pulse wave shape data and spirometric data from a test subject, and analyzing the pulse wave shape data and spirometric data with the subject characterization data for the known subject to confirm whether the identity of the test subject matches the known subject.
