A paper came out awhile ago showing that neural networks are extremely vulnerable to adversarial examples [1]. They showed even slight perturbations of an image generated with their method could cause NNs to misclassify it, but appear no different at all to a human. I am interested if methods like this could be used to extend the life of CAPTCHA a bit longer, even as computers are starting to beat even humans at object recognition tasks.

#132I had one read 'drink issue' once... Wasn't sure if normal capture or advice.

#133The squished-up word is the control word, and the straight one is the unknown one. You only need to get the wavy word right and just guess at all the cut-off examples.
I've solved a lot of captcha's in my time, and really have never experienced the trouble the author is detailing. Not only am I relieved when I see a reCaptcha since they are some of the easiest and most forgiving challenges, but I don't recall ever having repeated bad/unsolvable challenges presented on the same page. Sure, maybe sometimes you get a weird one and fail it. But typically the next challenge is easy to p…
have you tried this recently? zendesk's use of recaptcha was so bad that they are getting rid of it.
I personally experienced this and can't wait.

You need to realize that only one word needs to be entered. For the other word just enter any string (or even no string works in some/all cases).

I think you have made a good point and possible solution here. But I am keen to see if researchers can quickly address this issue with NNs. Someone might find an easy fix to this problem.

"Captcha's are not going anywhere anytime soon." Its turning in to the new version of "3rd world outsourced phone support" A strong indicator the user simply doesn't care about the customer experience. For some industries / companies, this is perfectly OK and BAU. For others it can be a company-killer. I see a captcha and I know the company doesn't like me, doesn't like what I'm doing, and doesn't care if I know how…

How the hell is anyone "to realize that only one word needs to be entered" when that's not what the instructions say to do?

If most other people entered the same thing then the word gets into the database, and your guess may not pass muster. So the question is - what percentage of users should be able to get the captcha before the answer is set?

You don't need to enter anything at all for the second (non-control) word
