This may seem like an ordinary challenge, but it's actually a mental battle between you and the machine.
In this "fully automated public Turing test that distinguishes between computers and humans," CAPTCHAs require us to complete a task to prove that we are not ruthless machines.
This process can sometimes be confusing, such as "Please point out the hill in **", and sometimes as simple as "Click here to confirm that you are not a robot".
But what is the real intent behind these tests?Isn't it true that a robot can't press that little button?
In fact, it is not.
While robots can easily press buttons, they struggle to simulate the small, unconscious movements of humans.
Even the most direct human actions have a certain randomness at the microscopic level, which is difficult for robots to imitate.
According to the cybersecurity company, the test closely tracks the user's movement as they move the cursor toward the box.
Even the most direct human actions have a degree of randomness at the microscopic level: tiny unconscious movements that robots can't easily imitate. If the cursor movement contains some uncertainty, then the test will determine that the user may be legitimate. ”
The test also digs deeper into the cookies your browser stores on your device, as well as your device's history, to further determine if you might be a robot.
For example, if you've browsed some cats' ** before ticking a box, liked a tweet about Greta Thunberg, or checked your Gmail account before working – all of these actions are silently telling the computer: You're human.
And in the process, we are declaring to the world: "I am a human, not a ruthless machine." ”
Often, such challenges are enough to convince the program that we're human, but occasionally we are asked to undergo other tests, such as whether our mouse tracks are too precise or whether our browsing history is more robot-like.
In the process, we may find that we can sometimes prove ourselves even better than real robots.
