Captcha – What do you really see?

On May 14, 2011, in Programming, by Akash Kava

I was trying to login to my Windows Live account and I may have mistyped my password but next screen locked me out for nearly 4 times asking me more and more difficult captchas.

What-Do-You-See-Captcha

What is Captcha?

Well there are some dirty people who write automated programs to login to website and steal data, so website owners needed something to identify the user as Human or Program. And they made Captcha, a real painful way to prove that I am a human.

Captcha Implemented wrongly on Windows Live

Now I have no way to know whether the password I typed was wrong or the captcha went wrong? Because the error message says,

Type your password and characters in the picture correctly.

So even after nearly 4th effort I posted this blog, because I have no idea what is this. I can figure out first character is probably X or it is a and e. Second character could be anything, A or n or even U for that matter.

Image Captcha is bad

I feel Image Captcha is very bad, I hear from senior citizens that they just cant read and cant understand what is it.

Bad Captcha Implementations

 

Windows Live

Great, just after my experience with Captcha, I posted this blog, that my second attempt of entering password got me feel guilty and I was presented to certify myself as a human.

StackOverflow

It is website where we ask and answer questions, always if I have answered and I may have realized spelling or semantic mistake and I go back to edit it quickly, this website turns on me thinking I am an evil computer program and posts me back a CAPTCHA thinking that it is very rare for a human to click and edit and correct spelling or words within 10 seconds.

I want to add more painful captcha implementations in this post so guys help me adding your own experiences.
