ECG biometrics during exercise remain investigational; leaves open validation before any clinical or security translation.
Can chaotic ECG signals recorded during muscular exercise be used for individual biometric identification?
ECG signals maintain unique chaotic features even during exercise, allowing for biometric identification with over 80% accuracy using support vector machine classification.
Lin et al. (2014) studied this question. Chaotic ECG signal analysis was evaluated on Successful recognition rate. Analysis of chaotic ECG signals using a nonlinear support vector machine with a polynomial kernel function achieved a successful personal recognition rate exceeding 80% during muscular exercise.
