What does “I am Not Robot” mean when visiting a site

CAPTCHA is a verification system from Google, to distinguish users between humans and robots.

When you access a site, we often have to fill in a CAPTCHA or verification system, a combination of letters and numbers.

The CAPTCHA is a test or acronym that stands for Completely Automated Public Turing test to tell Computers and Humans Apart or automatic public Turing test, to distinguish computers and humans.

Now, Google has changed the old CAPTCHA version, and replaced it with a version that can work quietly. These technologies will be applied to a new service called reCAPTCHA or “Invisible reCAPTCHA.”

Just like its initial function, reCAPTCHA is a free service from Google that helps protect websites from spam and abuse. It’s easy for humans to finish it, but it’s hard to “bot ” and other malicious software to find out. It is one of the tools used Running Room to ensure safety and security.

In the Internet world, the largest CAPTCHA service provider is Google’s reCAPTCHA.
