CAPTCHA stands for completely automated public turing test to tell computers and humans apart. The primary duty of Captcha is to separate humans and bots. Captcha generates a challenge response test and direct the users to perform a simple task. It is easy for the humans to complete the task, whereas it is difficult for the bot programs.Thus Captcha becomes a standard security mechanism in all the websites and web applications to prevent Internet Bots from unauthorised access.
