Why are the CAPTCHAs so unreadable nowadays ?
-
I am wondering why the websites nowadays are showing up the CAPTCHAs so dirty that even a software guy is not able to read it. He keeps on clicking the re-captcha button 8-10 times till a clearly readable (for humans) appears. The facebook CAPTCHAs are the nightmares for me... Some of the worst captcha samples online http://forums.nvidia.com/index.php?showtopic=84108 http://www.luuux.com/technology/unreadable-website-captchas http://www.socialreflections.com/unreadable-captchas-can-destroy-your-business/ I would like to give the worst captcha award to tagged.com . Try registering for the site and I bet 50% of the new users will close the browser without registering. Why dont these people go for a simple captcha with a varying background? Any thoughts? :^)

Worse than a KAKACAPCHA is a broken link. It's like saying you don't believe in Tim[^].

I think a CAPCHA that asks you to do math and authentication is based on the correct answer sounds good to me. Probably already tested and/or rejected though because I have yet to see one in action.

Because OCR is getting better. Things like KittenAuth are much harder to break for a computer, but easy for humans.

Yeah, that's be better than character recognition, cause computers aren't all that good at math. :-D Maybe if authentication was based on wrong answers?

Not only the wrong answer but you have to translate the wrong answer into another language that uses symbols and characters instead of letters and numbers. :)

I would like to give the worst captcha award to tagged.com . Try registering for the site and I bet 50% of the new users will close the browser without registering.Of the 4 samples there I found 3 obvious. The 3rd one is bad since the swirl obfuscates too much of one letter.
3x12=36 2x12=24 1x12=12 0x12=18

I thought all of them where pretty obvious, some of the easiest captchas I've seen in a while.

The recaptcha ones are bad because they are used to digitise books. Basically, every recaptcha consist of 2 words, 1 word that is known in their sytem, and 1 word that could not be digitised. If enough people give the correct answer for the valid word, and the same answer for the second word, they assume that the second word is correct to. So if you get a recaptcha, and you can only read one word correct, just type in random stuff for the second one it should work :) The ones on a colored background are a real PITA though.

What I hate most are those sites that clear every single field you've painfully filled in before and have you start all over again just because you didn't get the captcha right! Try log in at yahoo and you see what I mean (not to mention they even require you to manually type in the @yahoo.com suffix of your ID - how stupid is that?). The stupid thing about captchas is that it doesn't really matter how hard they are: if a bot does have a built in OCR software, it can just try over and over again and eventually it will find a match. It doesn't matter to the bot how hard the captcha is. It's not like it's running out of time somehow. If a bot does not have OCR built in however, even the most simple captcha would do. I highly doubt there is a significant difference between successuful bot registrations on sites with simple or hard captchas! Has anyone ever done a study about their effectiveness?
