Abstract
The utilization of photoplethysmographic (PPG) signals for biometric identification represents a novel approach in the area of secure authentication. PPG signals can be easily obtained with low cost and have great potential to serve as biometric identification mechanism. This paper explores the feasibility, along with the relevant signal processing methods, of using PPG signals of an individual as a biometric trait. PPG signals from two biometric datasets are examined. PPG signals were obtained from the fingertips of 29 healthy subjects. The experimental results demonstrate that PPG signals can be used as bio-measures for identification purposes given that PPG signals are collected under controlled environment and with accurate sensors.

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
