Generating Arabic Handwritten CAPTCHA for Cyber Security


Suliman A. Alsuhibany


Vol. 18  No. 3  pp. 41-47


The exponential growth of electronic services has led to the misuse of automated bots, which has resulted in serious security issues in terms of these services. Therefore, a CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a test to limit the ability of cyber attackers when it comes to scaling their activities using automated bots. Since several existing Latin script-based CAPTCHAs have been broken, this paper proposes a method for using Arabic handwritten text to generate CAPTCHAs. The rationale behind this method is that Arabic script and handwritten text have a number of advantages that may be beneficial for cyber security. Accordingly, an Arabic handwritten CAPTCHA generator is developed that produces Arabic handwritten CAPTCHAs. In order to assess the proposed method, experimental studies are conducted. The results showed a gap between machine and human recognition abilities while using Arabic handwritten script.
