Google reCAPTCHA helps keep your website safe from spammers and bots by requiring users to check a box or type the letters they see when submitting a form. You’ve likely seen reCAPTCHA before but there are a variety of implementations and Google is currently releasing a new version that we’ll explore below.

Introduction to Google ReCaptcha

How reCAPTCHA works is fairly complex but Google does give us an inside peek at the technology being used: “reCAPTCHA uses an advanced risk analysis engine and adaptive CAPTCHAs to keep automated software from engaging in abusive activities on your site. Every time our CAPTCHAs are solved, that human effort helps digitize text, annotate images, and build machine learning datasets. This in turn helps preserve books, improve maps, and solve hard AI problems”.

The NEW Invisible reCAPTCHA

In an effort to improve the user experience, Google is in the process of releasing a brand new option called “Invisible reCAPTCHA”. Essentially, Invisible reCAPTCHA works in the background while users are filling out a form to make sure they are legitimate users. Google doesn’t go into much detail on how it works, only saying that the system uses “a combination of machine learning and advanced risk analysis that adapts to new and emerging threats”. At this point, Google is keeping the technology very secretive – but for good reason.
