Key result
ECG biometric identification requires at least 10 seconds of data for optimal performance, and off-the-person acquisition (fingers) provides greater long-term stability than chest placement.
Why the study?
The study aimed to investigate the influence of the ECG collection protocol and uncontrollable acquisition variables on the performance of an ECG-based biometric identification system.
Comparison
Three data acquisition kits (dry finger electrodes vs wet wrist sensors vs wet chest sensors)

ECG-based biometric identification systems require at least 10 seconds of data and perform better with 'off-the-person' data acquisition.
Ramos et al. (2021) conducted an observational in Healthy (Biometric identification) (n=20). ECG data acquisition protocol variations (electrode placement, movement, segment duration) vs. Standard resting ECG / same session data was evaluated on Biometric identification performance (F1 score, accuracy). ECG biometric identification requires at least 10 seconds of data for optimal performance, and off-the-person acquisition (fingers) provides greater long-term stability than chest placement.
