Abstract
Two-factor authentication techniques using combination of magnetic cards and personal identification numbers (PINs) are widely used in many applications including automatic teller machines and point of sales. Similar to other valuable personal possessions, cards can be easily stolen by pickpockets. Furthermore, recent security reports show that magnetic cards can be easily duplicated using fake card readers and PINs can be obtained by shoulder surfing legitimate users' PIN entry processes. With this combination, criminals can easily break into users' accounts which represents a great threat. In this paper, we propose a new PIN entry scheme which is resistant against shoulder-surfing attacks conducted by shoulder-surfers with normal cognitive capabilities. Additionally, this scheme offers a relatively good level of security when the shoulder-surfer can record the entire login procedure for one or two times with a video device. Mathematical analysis of the proposed scheme is also presented.

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
