Only in the last 20 years, however, have researchers been able to apply digital analysis to the data [1]. Methods have been proposed to delineate ECG waveforms and their end fiducials from each heartbeat and using a strategy, which uses the delineated features, and taking decision for the identity of an individual with respect to the template database on the basis of match scores. This paper aims at improving the idea of ECG as a new biometric characteristic in...
