Abstract

CAPTCHAs are widely used by websites for security and privacy purposes. However, traditional text-based CAPTCHAs are not suitable for individuals with visual impairments. We proposed and developed a new form of CAPTCHA that combines both visual and audio information to allow easy access by users with visual impairments. A preliminary evaluation suggests strong potential for the new form of CAPTCHA for both blind and visual users.
