Did you know that Ikea, ASDA and Tesco are either acronyms or portmental?
Even Lego, Haribo and Twix have hidden meanings.
But while some believe that WiFi stands for “Wireless Fidelity”, Phil Belanger, a founding member of the Wi-Fi alliance, revealed that “WiFi stands for nothing. It is not a acronym. There is no meaning.”
I will be honest: I always thought of Captcha’s same, these tests that you carry out to prove that you are not a robot.
At best, I thought the name was a piece for “captions” as well as for “capture” or the recording of an image (some of them contain click-the-pic pictures).
I was predictable.
What does Captcha stand for?
Although the technology that led to Captcha already circulated in the 1990s, in 2003 it needed a number of computer scientists from Carnegie Mellon University to start Captcha.
They were inspired to create the system after having a yahoo! Exec talk about bots that register for millions of fake e -mail accounts.
The name stands for “Fully automated public Turing test to say computers and people apart,IBM reports.
A Turing test is a test that Mathematician Alan Turing proposed to find out whether a machine can really “think”.
He also created the “imitation game”, which is now generally known as the “Turing test”, in which humans are asked to differentiate a person generated by humans to certain questions from a mechanical manufacturer.
Since the captcha tests aim to tell computers apart from people, the name basically means “automatic bot detector”.
How does the tick of a box show that I am not a robot?
This makes sense for the image and distorted text tests that most of us combine with captcha. But what about the boxes that you check and just say “I’m not a robot”?
After Cloudflare, these tests (which are actually recaptcha) do not examine the “actual action of clicking on the check box – it is all that leads to the check box -click”.
They take things into account on how to move your cursor into the box. In humans, these movements have an unavoidable element of microscopic randomness that bots cannot imitate.
In addition, Recaptcha’s things look like their biscuit history to determine whether they are a person or not.
