Completely Automatic Public Turing Test to Tell Computer and Human Apart (CAPTCHA) is a challenge response test which is a security method in web-related services aiming at distinguishing between human users and computers. Although nowadays the use of CAPTCHA is becoming a standard security method, this specific type of textual verification hinders accessibility to users with reading difficulties, such as individuals with dyslexia or low vision. In this paper, we present a novel text-based CAPTCHA which comprises several accessible components and adaptable settings in order to facilitate access to individuals who face reading difficulties.
