As we all know the main and basic feature of CAPTCHA is to stop spamming. Till today we were using ReCAPTCHA feature, users needed to enter the letters seen in the image which were being used to digitize the books, improve maps and solve the AI problems.

Why “No CAPTCHA reCAPTCHA”

Google was thinking that the old one is very time consuming, why they can’t use simpler and more accurate way. They figured out that it would be easier to directly ask to humans, whether they are humans and not robots.

So they started to implement such API that can work to simplify the reCAPTCHA experience. Only user with one click can verify that they are human and not robot in a secure manner.

Research shows CAPTCHAs are not the thing on which we can rely any more as today’sArtificial Intelligence Technology can solve even the most difficult variant of distorted text.

 

One more layer of security

Don’t think, No CAPTCHA reCAPTCHA is just a click on checkbox, it has one more layer to enhance more security. In case if the risk analysis can’t predict about human or robot, it will prompt a CAPTCHA as a security checkpoint.
