CAPTCHA

Submitted by Corey Smith on Thu, 03/20/2008 - 05:19

Completely Automated Public Turing test to tell Computers and Humans Apart.

Just the name is annoying. Have you seen this anywhere? Do you know what it is? This is the stupid little box at the bottom of many forms that ask you to validate if you are human or not. Some are simple (like add 2 + 2 and input your answer). Some are obscured text to input. Sometimes they are downright impossible to decipher. I had to try 4 times the other day before I could get my account set up on one site.

John points us to a list of the worst CAPTCHAs found on the web. If you find worse, let me know. Here they go:

Bad Captcha 1

Bad Captcha 2

 Bad Captcha 3

 Bad Captcha 4

 Bad Captcha 5

 Bad Captcha 6

 Bad Captcha 7

 Bad Captcha 8

Corey, I was in my firewall vendor's support site, logged in mind you, and they now have added a CAPTCHA to the ticket submission... that's insane! I have had to experience the wrath of a hacker to a form site we used at work, and luckily it was only about 10,000 e-mails in 10 minutes and 3 days of that site being down ! I know there are some reasons to use them, but I agree that some are way to hard to figure out...

Hi Corey, as hackers continue evolving, these CAPTCHA will be more and more difficult for the human eye. Be prepared. Buy glasses. Study math!

Those are brutal! What about the best CAPTCHA's? I've been trying to find one that is easy to install. Any suggestions?

I recognze that sometimes you can't get away from preventing spam. On a blog, I just use Akisment and don't use anything (as you can tell). For Drupal, there is a module called CAPTCHA Riddler. It allows you to create simple questions that require at least a little logic to answer. I have seen them as simple as "What is one plus one? Or What color does Blue and Yellow make? You can create your own text field that does this if you like and then update it manually on a regular basis, but it may not solve the problem.

I just released a script that prevents spam from forms with out the irritating image based captcha (for designers who want to download or comment on it, just click the link in my name above).  Anyway, I love the images you have of bad captchas.  I was wondering if I could use one or more on my blog in the article annoucing this script?

 

You have some of the best bad examples I've seen yet.

so what say you will you help me Stop Form Sapm and pu and end tothese irritating image based caotcha's that don't work (there's a couple programs out there for spammers that can read the captcha image now).
