Abstract

Many existing CAPTCHAs require users to identify characters in a static image and match them with their counterparts in another image. Requiring intelligent human interaction in the matching task of these CAPTCHAs will pose a second challenge, which is straightforward for human users but difficult to emulate for Bots. In this paper, the authors develop several interactive matching tasks involving dynamic elements and demonstrate their impact on CAPTCHA security and usability in a series of tests and user studies. Their tests indicate that requiring intelligent human interaction can substantially decrease the likelihood of a CAPTCHA being broken in addition to making an attack computationally expensive. The authors' results provide both a security and a usability benchmark for the development of interactive dual-challenge CAPTCHAs. Their proposed findings from users' mouse movement data analysis can be readily incorporated in several types of existing CAPTCHA to enhance their security.
