Abstract: In this paper, we propose a new data compression based ECG biometric method for personal identification and authentication. The ECG is an emerging biometric that does not need liveliness verification. There is strong evidence that ECG signals contain sufficient discriminative information to allow the identification of individuals from a large population. Most approaches rely on ECG data and the fiducia of different parts of the heartbeat waveform. However nonfiducial approaches have proved recently to be also effective, and have the advantage of not relying critically on the accurate extraction of fiducia. We propose a non-fiducial method based on the Ziv-Merhav cross parsing algorithm for symbol sequences (strings). Our method uses a string similarity measure obtained with a data compression algorithm. We present results on real data, one-lead ECG, acquired during a concentration task, from 19 healthy individuals, on which our approach achieves 100% subject identification rate and a n average equal error rate of 1.1% on the authentication task.
