Abstract

A method of determining information concerning the identity of an individual comprising measuring at least one biometric of the individual comprising at least one bio-potential waveform generated by the individual's heart, extracting a plurality of characteristics from the bio-potential waveform comprising any of an approximate location of a point of a P peak, an approximate location of a Q-point of a QRS peak system, an approximate location of an R-point of a QRS peak system, an approximate location of an S-point of a QRS peak system, an approximate location of a point of a T peak, using the characteristics to calculate at least one waveform parameter, comparing at least one calculated waveform parameter with at least one previously-acquired waveform parameter to generate a score, and using the score to determine information concerning the identity of the individual.
