Abstract:
This paper compares the authentication
performance between three topological structures of the Pulse
Active (PA) technique as applied to Electrocardiogram (ECG)
biometrics. PA is a feature extraction method derived from the
concept of Pulse Width Modulation (PWM). PA decomposes an
ECG signal into a series of output pulses based on the linear
dependency constant setting between the ECG and the
modulated signal. In this work, three types of periodic signals
namely triangular, sinusoidal and cosine waves are assigned as
the modulation signal of the PA topology. The authentication
performance of these periodic signals to generate output pulses
and feature vector are analysed and compared. In this work, PA
topology using a triangular function as the modulation signal
outperforms the use of sinusoidal and cosine waves in PA-ECG
based authentication system.
