Abstract -
Captcha is the abbreviation for completely automated public turing test to tell computers and humans apart. Captcha is a security mechanism which determines whether the online user is human or automated programs known as bots. Captcha ask the user to perform some task to prove him as human. It is easy for humans to complete the task but difficult for bots. Thus Captcha become a standard protective arrangement in all the websites and web applications to prevent the entry of bots which perform malicious activities such as spamming, scalping. This paper analyzes the various types of Captcha methods engaged in different websites as a security arrangement and their merits and demerits.
