When I first heard captcha I thought it is some relaxed pronunciation like gotcha. Hey! I caught you! Some sort of an exclamation over an unexpected capture. My vocabulary of jargons definitely needs to be worked up. Well, a Captcha is nothing but one of those word verification processes where you are given a distorted image and asked to type in what you make out of it. It aims to differentiate human beings from bots. Entering the correct answer strengthens the user's probability of being a human.
(Picture courtesy of geekandpoke.typepad.com)Captcha stands for Completely Automated Public Turing test to tell Computers and Humans Apart. The first captcha was developed to be used by Yahoo. Though the whole idea is security, sometimes it can get extremely annoying. I don't really like them. In fact I hate them. (A hate post immediately after a love post is just not intentional at all.) The other day it took me three attempts to get convinced I'm not a human. Calling off the registration seemed easier. 20% of the time, I just can't decode them. With captchas like these can you ever prove your existence?

The technology is used mostly to block spammers and bots that try to automatically harvest email addresses or try to automatically sign up for or make use of Web sites, blogs or forums. CAPTCHA, whose users include Yahoo and Google, blocks automated systems, which can't read the distorted letters in the graphic.
One of the problems with CAPTCHA is that sometimes the characters are so distorted that they can't even be recognized by people with good vision, let alone visually handicapped individuals.
Didn't you do a seminar on Neural networks ?
Google's search bots took a snapshot of some site you posted your resume on.I was verifying your e-mail and found all this
Like the with hologram in the movie I-robot,you just have to ask the right question.
Thats were the captchas come in,they are the sentries of the internet.
With advancements in Neural Networks,soon there will be bots that can be 'thought' to read the captchas.
But can the agents match humans at perception?.
Future Generation of Captchas
Way to go! Are you doing some research on artificial intelligence? Yeah I did some study on facial recognition using neural networks way back in 2003. It's actually very interesting.
I studied both AI and Neural Networks(+fuzzy systems) in Engg,however the syllabus was ridiculous.
What fascinated me was the Artificial Agent,more so the autonomous Agent.
Until then I didn't know that Google and well all of the web uses crawlers,and bots and botnets to bring us these results in 0.25secs
(of course not included in my syllabus which was crap)
I have been experimenting with search engines which is why I find things that usually others don't.
Only recently I started looking at Search Engine Optimization, which is the other way round(ie not finding things you want but getting your thing up there on the first page for people to find)
Will that be of any help to me :P
Can I hire you!
Minu, couple of months back, I came across an innovative captcha.
Here you dont have to stress your eyes to read those funky letters, its just some plain text with letters in different colors and we are asked to key in letters which were in a specific color. Isn't it cool.
Oh yeah these captchas come in a lot of variety..Did you check out that link I had in the post..
You gave me a new word and a definite question for the next quiz I conduct!! Whats a captcha??? And the comic strip in ur post takes the cake.. lovely..
Sajeev’s comment to the post definitely made it much more interesting and informative… to a great extent, he succeeded to neutralise your “hate-post” effect..
I refer to an earlier comment of Sajeev’s regarding getting captchas like biles and faeces.. How interesting… all I get is boring skewed illogical alpha-numerals making u wonder whether it is the numeral “1” or an upper case “i” or a lower case “L”..
But lemme tell u, Ik hou van Captcha… I love captchas... Just for the fun of doing it.. Isn’t there a kiddish excitement in typing out these words and checking whether we got it right???
try miniclips.com...they have better games online (http://www.miniclip.com/games/bloxorz/en/) You may even try acno's energizer. Leave the captchas alone :) I don't like them unless the letters are neatly laid out or it is some simple association / match the following tricks to solve it...as I said the other day the captchas kept reloading (thrice) and I got pissed. That's when the hate element sprouted in my mind.
