Abstract

fetched live from OpenAlex

Visually impaired individuals are increasingly reliant on the Internet in their daily lives. Yet, existing security mechanisms may not sufficiently help these users protect their online security and privacy. We explore this issue through two complementary studies. First, we conduct an expert evaluation to assess web-based security cues through JAWS. We propose a set of 9 heuristics combining usable security and web accessibility principles to guide our expert evaluation. We uncover several severe issues that are not identified by automated accessibility checkers. Second, we conduct a task-based user study with 14 visually impaired users to observe their security habits and concerns when navigating the web. Again, our findings suggest that severe usability issues lead users to take risks or force them to choose between accessibility or security. Based on our findings, we provide practical recommendations to remedy these issues by tailoring security information to effectively communicate with visually impaired users.

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.
