Have you ever wondered how the computer finds out with just one click of yours that you are a human and not a robot?

Under which a small box is given, where you can go further on the website only after clicking. In such a situation, many people must be thinking why do I have to prove to the computer that 'I am a human and not a robot.' At the same time, many people must be thinking about how does the computer understand as soon as I click that 'I am a human and not a robot.' If you also do not know and you are also looking for the answer to this question, then this news is special for you.
What is 'I am Not a Robot'
Even though 'I'm Not a Robot' seems like a small and simple click. But this simple click is a part of the very complicated CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) system. That is, a test that differentiates between humans and machines. In such a situation, all websites use this system to avoid activities like robot attack spam, fraud, data scraping.
The system starts checking even before you click
The 'I'm Not a Robot' CAPTCHA system seems easy, that one click and the computer finds out whether the person in front is a human or a robot. Whereas in reality the computer system is already keeping an eye on your behavior. Even before you click on the option of 'I'm Not a Robot', the computer system checks your page interaction. The computer system understands your mouse movement, scrolling and clicking speed. Because, the cursor movement of us humans is different and unusual. Whereas the cursor movement of a robot or bot is different and very accurate. Which makes it easy for the system to understand whether the person in front is a human or a robot.
Details of your device are also checked
By clicking on 'Im Not a Robot', the computer system not only checks the cursor movement but also the details of your device. Which is called browser fingerprinting. Under this process, the system checks your device's IP address, browser version, time zone, installed plugins, screen size etc. Through which the system finds out whether your browsing setup is normal or not. At the same time, if something is not normal like headless browser or VPN, then you will be given the next process.
Visual challenge
If the system feels that your identity is not clear, then it will give you a challenge like choosing traffic lights, car or bicycle. Because, bots face a lot of difficulty in such tasks whereas humans can do it easily. In simple words, this is an advanced system that verifies your identity. It checks your every action, how you clicked, what is your mouse movement. This is what determines whether you are a real person or a bot.
