Google’s reCAPTCHA becomes Invisible

You might have seen many kinds of CAPTCHA on the web, mostly when trying to do sign-in or sign-up.
Some captchas will ask you to solve simple maths, or type the words shown on distored image, or select certain objects in a grid of pictures, or just click a checkbox.
This CAPTCHA entry is required to separate humans from spam bots.


reCAPTCHA is the famous CAPTCHA service currently owned by Google.
Hereafter we won’t be seeing these captcha entry screens much. That does mean that CAPTCHA service will be removed from web page. They will continue to exist. But Google is making them invisible.

Since the launch of No CAPTCHA reCAPTCHA, millions of internet users have been able to attest they are human with just a single click. Now Google is taking it a step further and making it invisible. Human users will be let through without seeing the “I’m not a robot” checkbox, while suspicious ones and bots still have to solve the challenges

reCAPTCHA is a free service that protects your website from spam and abuse. reCAPTCHA uses an advanced risk analysis engine and adaptive CAPTCHAs to keep automated software from engaging in abusive activities on your site. It does this while letting your valid users pass through with ease.

reCAPTCHA offers more than just spam protection. Every time Google’s 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.
