Have you ever wondered about what is the most ideal check to protect your web forms from spambots? CAPTCHA is one of the most ideal checks that most people don’t notice, but it keeps out all the bots and spammers effectively.
You have probably seen web forms where you need to enter some strings that permit you to submit the form and that string is nothing else than CAPTCHA. The program is like a validation code that distinguishes between real humans and internet bots. Many of the website owners face trouble and meet unique challenges in protecting their web resources from automated spam bots. CAPTCHA is the answer to all such menaces.
CAPTCHA creates a significant accessibility barrier, as a user has to devote an extra effort, sometimes, to understand the alphanumeric strings that are badly distorted and difficult to read. People with partial sight or visual disability, cognitive disability like dyslexia, face much trouble to translate the string into normal characters to be entered in a text box. This defeats the purpose of CAPTCHA and damages accessibility of the website, as it poses a challenge even to real humans.
