Abstract

CAPTCHA “Completely Automated public Turing test to tell Computers and Humans Apart” is a program used to check whether a user is human or computer program by creating tests that is easy to human but difficult to computer programs. In this paper a new schema of Arabic CAPTCHA is proposed to generate Arabic characters and numbers by using generators that combines more than one LFSR via a non-linear function to produce the binary sequence, this random binary sequence is converted 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.
