Now Even Photo CAPTCHAs Have Been Cracked 340
MoonUnit writes "Technology Review has an interesting article about the way CAPTCHAS are fueling AI research. Following recent news about various textual CAPTCHAs being cracked, the article notes that a researcher at Palo Alto Research Center has now found a way crack photo-based CAPTCHAs too. Most approaches are based on statistical learning, however, so Luis von Ahn (one of the inventors of the CAPTCHA) says it is usually possible to make a CAPTCHA more difficult to break by making a few simple changes."

Good idea. Here are a few questions to start with:
1) What is the best editor: Vi or Emacs?
2) Was there a cabal?
3) Did Romero make you his bitch?
4) Rick Astley would never: give you up; let you down; run around and desert you; make you cry; say goodbye; tell a lie and hurt you?

So CAPTCHA images are ineffective at blocking the bots. No surprise. It won't be long before these AIs start joining Yahoo or Google mail for the same reasons we do: Chatting.

you're pitting a machine generating questions and answers against a machine designed to answer questions.
You make it sound like that's hard. Here's a question that a machine could generate that another machine could not answer:
"What number am I thinking of?"

That'll really foil spammers, because it is impossible to solve the AI problem from that angle as computers will never be as dumb as the average human.

Asking simple math or site-relevant questions are not only easier for humans (I'm talking about "What's 5 - 3") to read, but they're harder for automated parsing by software to crack.
If you really wanted to screw with these bots, you would've made the question 4 divided by 0. :-)
