This paper presents a biometric recognition system based on the Electrocardiographic signal (ECG). The proposed system is based on a state-of-the-art recognition method which extracts information from the frequency domain. In this paper we propose a new method to increase the spectral resolution of low bandwidth ECG signals due to the limited bandwidth of the acquisition sensor. Preliminary results show that the proposed scheme reveals a higher identification rate and lower equal error rate when compared to previous approaches.engBiometric recognition systemElectrocardiographic signalFrequency domainInformation privacyLow bandwidth ECG signalsSpectral resolutionconference object10.1109/HealthCom.2013.6720731
