CAPTCHA.. ever heard ??
If not heard definitely seen every where.. These are image code verifications. CAPTCHA is a contrived acronym for Completely Automated Public Turing Test to tell whether its a person or a computer because CAPTCHA are one of the very few things which are next to impossible for computers even and a cake walk really for us.
This should ring a bell..
Captcha are used to prevent automated softwares from performing actions to stop spammers. Many of us hav seen them on orkut , rapidshare and many more places. But but.. Mostly like orkut uses 4 letter words or 5 letter words. Which sum upto 12338343 combinations.
I was actually scrapping one of my friends on orkut with a link , and it gave me this really funny image verification code which took me quite sometime to register in my brains while scoffing at it . Have a look and you'll understand ..
Let the pictures tell you everything ! [ Eyes open boy, Not ears.. ;-) ]
