Differentiating between humans and bots has become a critical issue of websites' security. Therefore, a completely automated public Turing test to tell computers and humans apart (CAPTCHA) is a test to limit the ability of cyber attackers trying to scale their activities using automated bots. Several Latin-based CAPTCHAs, which are widely used, have been broken, while Arabic script and handwritten text have inherent characteristics that have been proven to be beneficial for cybersecurity. Accordingly, we proposed a method for using Arabic handwritten text to generate infinite CAPTCHA challenges. In order to assess the proposed CAPTCHA generator, experimental studies were conducted. The results show a gap between machine and human recognition abilities while using Arabic handwritten script.
