Abstract
The identity of an individual (known or unknown) is determined by a sonic profile of sounds issued through his oral-nasal passages. The sounds are converted to digital electrical signals and produce a three domain format of frequency, amplitude and time samples to produce an array of peaks and valleys constituting the sonic profile of an individual. A source or library of a sonic profiles in the same format of a known individual have the interrelationship including relative positions of said peaks and valleys of said sonic profile of the known individual with that of said unknown individual compared and a utilization signal is provided upon a detecting or non-detecting a correlation between said sonic profiles.
