Know about various captcha solving
services
We all have heard about the term captcha solving but do you know what
does captcha means? The term captcha stands for “Completely Automated Public
Turing test to tell Computers and Humans Apart”. The captcha phrase was first
used by the people of Carnegie Mellon University in 2000 named Luis von Ahn, Manuel
Blum, Nicholas Hopper, and John Langford. In captcha there is a term Turing which
means a repeatable test of the computer ability to deal with the human
intelligence.
Computer can easily make human a
fool by making him think that they are talking to the other human and the
machine forwards the test. In 1950 a test used to be conducted named “computing
machinery and intelligence” which was commenced by Alan Turing. A captcha or
challenge system is mainly used to see that the one who is working is a human.
Captcha is in the form of text, pictures or sound that cannot be easily
understood by the automated computers or robots.
Earlier the captcha solving test
was only for the people who have vision problems, hearing problems, small
children and abnormal people. But nowadays captcha or challenges systems are
only for those people who have perfect vision, perfect hearing and who can
easily solve the computer puzzle. In the year 2007 these tests used to be quite
simple. Captcha solving service is
provided by many companies in the market if you search about them. In the year
2007 it was estimated that 160,000 human hours a day were spent in solving
these puzzles at ten seconds per try.
It is no wonder if the number has
been reached closer to a million human hours per day and you can note this
thing by noticing number of times a person retry to solve the puzzle. Some are
quite easy to solve. When someone visits captcha.net they come through some
simple examples that anyone can solve. But the problem which arises these days
is the tests are made to defeat Optical Character Readers (OCRs). The words and
numbers are jumbled in such a way that an average person has to make some
retry.
This service is provided by many
companies in the market but one of the leading companies which provide the cheap captcha solving service is Asia
virtual solution. The numbers and alphabets are jumbled that even a teenager
cannot solve them and then they move back to the simple tests like addition of
two numbers, deformation of simple text etc. Captcha solving is worse for those
people who have vision problem because so much of efforts are involved in it.
Facility of audio button is also available where person can try by listening,
not by reading. One can try this and get to know that whether the audio is
easily understood or not.
