Key result
Non-fiducial ECG algorithm using window removal and LDA achieves 100% subject identification.
Why the study?
Accurate individual identification using ECG signals requires improved feature extraction methods that handle both normal and abnormal signals effectively.
Population
ECG signals from Normal Sinus Rhythm, PTB diagnostic, and QT databases
Comparison

May advance ECG biometrics research; leaves open prospective validation before any clinical use.
A novel non-fiducial feature extraction method with window removal achieves near-perfect subject identification rates using ECG signals from standard databases.
Jung et al. (2017) studied ECG Biometric Identification (n=104). Non-fiducial feature extraction with window removal method vs. Without window removal method was evaluated on Subject and window identification rates. The proposed non-fiducial ECG identification algorithm using a window removal method and LDA classifier achieved a 100% subject identification rate and up to a 99.23% window identification rate across three databases.
