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?
