ReCAPTCHA is a free service that protects your site from spam and abuse. It uses advanced risk analysis techniques to tell humans and bots apart. With the new API, a significant number of your valid human users will pass the reCAPTCHA challenge without having to solve a CAPTCHA. ReCAPTCHA comes in the form of a widget that you can easily add to. Google reCAPTCHA protects you against spam and other types of automated abuse. It is used to stop spam on a website and verify whether a user is a human. This article provides an example of implementing invisible reCAPTCHA on an ASP.NET Login page.
