| Abstract | ||
| Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) is a program where its goal is to check the user identity if it is a human or web program by creating tests that is easy to human but difficult to computer programs. In this paper, a mixed Arabic CAPTCHA schema is proposed to generate Arabic characters and numbers using generators that combines more than one Linear Feedback Shift Registers(LFSRs) via a non-linear function to produce the binary sequence. This random binary sequence is translated to be Arabic characters and numbers to be used for Arabic CAPTCHA, to ensure the randomness, each generator output is analyzed via randomness analysis using National Institute of Standards and Technology (NIST) statistical test suite. | ||
