CAPTCHA

Post by alphacentauri » Sun Aug 22, 2010 10:15 am

Okay, CAPTCHAs are officially out of hand.

I just got a reCAPTCHA when I posted a WOT comment that included this mathematical forumula:

βσ2t-1

Not only did it include Greek characters, the 2 should have been a superscript and the t-1 a subscript. I had to use Microsoft Word to get the beta and sigma to paste it in, as I don't have a Greek keyboard.

You could have just requested a refresh of the Capatcha and would not have had to go through that pallaver. ;)

It seems reCAPTCHA has turned up the difficulty level recently... :)



Yes, requesting a new one should solve the problem.

Cant say I have seen any of these hense my previous comment. I must admit that this too would give me a headache when faced with it. Lets hope the new one does the trick.

It's supposed to have a purpose

The whole idea of reCAPTCHA is that only one of the images is the test. The other is something in a literary source that OCR software is having trouble identifying. Having people who solve CAPTCHAs also help decipher those is useful to digitizing books, especially works whose only hard copies are aging and at risk of being lost. ("Stop spam. Read books.")

If you know which is which, you can enter anything you want for the literary source image and still be able to get credit for solving the entire CAPTCHA. It isn't really necessary to ask for another, as the whole reason the second image is there is that there is no right answer for it yet. But you're potentially poisoning the statistics used for the OCR software. That's why I did go to some trouble to provide an accurate answer. There's examples of how it works here: http://www.google.com/recaptcha/digitizing

If they're going to give examples that use non-English keyboards, they need to find a way to matching it with users using those keyboards. Perhaps they used to and it's gone on the fritz?

Not exactly. In fact, both are from books that couldn´t be read. But one is identified, which means that you still can enter something different, like change a letter, and it will work. The other could be neglected. It´s pretty easy to see which one should be entered.

sorry I meant to say about "leaving you with roses " == I read the posts , and I could not understand why OP would not listen , but that is life = b/w ARGH = do you think , that a key board in Greek [ down loaded ] could have resolved the problem of using some words to create a password ? thank you

@AlphaCentauri

Consider it just another Anti-Bot check. Who knowing the fact that cannot reproduce such characters, would try to write that two words, instead of simply ask for another couple? ;o)
