CAPTCHA is actually an acronym that stands for Completely Automated Public Turing test to tell Computers and Humans Apart. A CAPTCHA is actually an inverted Turing test whereby a machine tests to see if you are human or not. Now Google introduced a new re CAPTCHA procedure to verify a robot and it is very simple. You just need to “click” on the check box to complete verification instead of typing distorted text in text box.

By using this new API, a significant number of users will be able to securely and easily verify they’re human without actually having to solve a CAPTCHA. Instead, with just a single click, they’ll confirm they are not a robot. Here the video to explain you more about this.
However, CAPTCHAs aren’t going away just yet. In cases when the risk analysis engine can’t confidently predict whether a user is a human or an abusive agent, it will prompt a CAPTCHA to elicit more cues, increasing the number of security checkpoints to confirm the user is valid.
This new API re CAPTHCHA’s are more user friendly in mobiles. Here the below images explain you about this more. You can see a CAPTCHA based on a classic Computer Vision problem of image labeling. In this version of the CAPTCHA challenge, you’re asked to select all of the images that correspond with the clue. It’s much easier to tap photos of cats or turkeys than to tediously type a line of distorted text on your phone.
