Abstract

fetched live from OpenAlex

Security proponents heavily emphasize the importance of choosing a strong password (one with high entropy). Unfortunately, by design, most humans are apparently incapable of generating such passwords, or memorizing a random-looking, machine-generated one for longterm use. Infrequently used passwords pose even bigger security and usability problems. We exploit the fact that many users now own or have access to a large quantity of digitized personal or personally meaningful content in designing an object-based password scheme called ObPwd. ObPwd enables users to select a password generating object from their local collection or from the web, and then converts the password object (e.g. an image, a particular piece of music, excerpt from a book) to a (potentially) high-entropy text password that can be used for regular or secondary web authentication, or in local applications (e.g. encryption). Instead of requiring users to memorize an exact password, ObPwd only requires one to remember a hint or pointer to the password object used. We believe that choosing digital objects as passwords is an interesting alternative to explore, and may enable users to create and maintain high quality passwords. We have implemented a prototype, and solicit feedback from the research community in regard to using digital objects as passwords. 1

Full frame distilled prediction

Teacher imitation

Not 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.
