Abstract
This work analyses the feasibility of electrocardiogram (ECG) biometrics using signals from a novel single arm single-lead acquisition methodology. These new signals are used and analysed in a biometric recognition system in verification mode for validation of a person’s identity enrolled in a system database. The algorithm used for recognition in the proposed system is the Autocorrelation/Linear Discriminant Analysis (AC/LDA), which is combined with preprocessing stages tuned to the characteristics for ECG from the single arm. The signal is collected from 23 subjects in three scenarios and performance of the proposed scheme is evaluated. Considerably low Equal Error Rate of 4.34% is obtained using the described method, establishing the utility of these signals as viable candidates for ECG Biometrics.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
