Want to download pictures from a site, or apply
something to a site. Suddenly multiple pictures appeared on the computer
screen. Now you have to make a choice from there bridge or car or traffic
light. This whole thing is captcha. But why? What is the reason
behind this? What is the CAPTCHA?
It is difficult to find a person who uses the
internet but is not familiar with Capture. Basically differentiates
between Human User and Automated User.
Details -
Suppose someone is trying to do something on the
Internet. Now the specific website will try to understand whether you are
the right user. This means that the work that you are going to do through
the internet can be understood whether a human user is really doing it or a
robotic user is doing that work.
Captcha contains different images or different
characters. They can't normally read robots. As a result, by looking
at them, a website can understand through captcha code whether the user is a
human or a robot.
What are the
functions of CAPTCHA?
Captchas are used in blogs and forums to prevent
spam comments, prevent invalid accounts, and maintain the accuracy of polls.
Why am
I writing a robot ?
Before we get into that, we need to say a few
more things about Captcha. At the moment Google has the most advanced
technology in the world to create Captcha. But here a complex problem is
created. Among the most complex captchas Google saw in 2014, their machine
learning algorithm (MLA) was 99.8 percent successful. But in the case of
ordinary people it was creating problems. Only 33 percent of ordinary
people were able to do it correctly. So Google introduced a new
method. Named NoCaptcha ReCaptcha.
What is the NoCaptcha ReCaptcha method?
In this way the machine monitors the data and
behavior of Internet users. It allows some users to test I am not a Robot
and some users to test images.
