A CAPTCHA is a type of challenge-response test used in computing to determine whether the user is human.

In this case the form that you are filling out contains a CAPTCHA that you (the user) need to complete before being able to submit this form.

By asking you to complete the word found in the image we can make sure that you are a human user rather than a computer program such as a spam robot. This ensures you/the talent receive no spam messages to your/their email account.
