What is a Captcha? And How It Can Help You Protect Your Website

They were originally designed to prevent automated bulk spam on websites by requiring the user to enter a special code displayed in an image. Most captcha services used distorted text and pictures containing random letters to create these images. The idea was to make the captchas easy to read for humans but difficult to decipher for computers.
