Forms and Captchas

Captchas

Definition: A captcha is a distorted image of letters and numbers used to prevent automated use of websites; Anything that a human must do to prove that they are not a computer. Captchas are most frequently used in submission forms.

There are a lot of different types of Captchas around, some accessible and some not. A good accessible Captcha goes by the name of reCaptcha: an important element is that it has an auditory component in it to help a visually impaired person to submit the web form. Screen readers cannot recognize a displayed distorted text. In order to enable this Captcha for your website, you will need to go to http://www.recaptcha.org and sign up for a free account. You will be presented with both a Public Key and a Private Key which are to be used with your reCaptcha code, or in a reCaptcha enabled plugin. Don’t worry, there are plenty of code snippets and tutorials on the website to help you out.
