summary

DualCheck embeds 10 multiple-choice online-safety questions into a CAPTCHA-like flow and collects cursor behavior to run verification similarly to reCAPTCHA v2 (actual reCAPTCHA code is not integrated). A 15-day deployment with 34 participants shows mean accuracy on the question set rises significantly from day 1 to day 15, no significant difference between one-time and repeat-until-correct modes, and higher perceived usability (SUS) than text- or image-based CAPTCHAs.
