Abstract
This paper describes the development of a biometric authentication system in a battery-powered locking device. It differs from the conventional locking system, which connected to an external power supply. The system focuses on a fingerprint-based identification with single button operation. A fingerprint sensor readily available in the market was integrated with an Arduino as the processing unit to unify the button operation as means to trigger functions on the fingerprint sensor and actuator motors, as well as indicating lights for user feedback. The aim of the seamless fingerprint authentication requires a brief matching of users’ fingerprints. A prototype of the system was built and tested. It was found that the device is able to match a fingerprint in less than 1s for up to 50 registered fingerprints. Using a nominal battery capacity of the 12V lithium battery pack with 5000mAh, the amount of current supply to the actuator is sufficient for 400 activations.

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
