What is Image Verification ( Captcha )?

Image Verification or Captcha is a security test to determine whether or not the user is human. This ensures that only human visitors can actually submit a form, and not spamming bots that are browsing the web from site to site submitting spam where they can.

Fortunately, it is impossible for a non-human, in other words a computer program, to extract a word or a combination of letters and numbers from an image, especially if the image is distorted. We use a type of Captcha that requires you, the user, to type a mixture of letters and digits from a distorted image that appears on the screen. Using this Image Verification security method ensures that only people actually can submit the form.
