Captcha is an acronym for “completely automated public Turing test to tell computers and humans apart”. It is a method of differentiating human users from “bots”, software that tries to make use of your website / online tools. Captchas can help protect information and your storage/bandwidth from being eaten up by automated processes. Normal Captchas are text based with small letters capital letters and they are irregular in their positions with various color options.
