Abstract
Historically, there has always been a trade-off between usability and security. In addition, increased security also tends to increase the complexity of interfaces for users with disabilities. This research paper has three important components: 1) a focus group with blind users to determine their top 10 security-related challenges, 2) development of a new prototype to address one of the challenges for blind users, and 3) evaluation of the prototype with five visual users and five blind users. The prototype developed is a new form of CAPTCHA, based on the combination of non-textual pictures and sound clips, which is equally usable by both visual and blind users. Data collected shows that this new form of CAPTCHA is preferred by both blind and visual users to previous forms of text-based CAPTCHAs. Future directions for research are also discussed.
