CAPTCHA poate fi spart

You know those annoying, hard-to-read CAPTCHA text images that Web sites make you type to prove that you're not a machine? Vicarious, a California-based artificial intelligence startup, claims to have written software that can successfully interpret and reproduce the text inside the CAPTCHA image with 90% accuracy.

If it's true, that's better than what a lot of people can do with those skewed letters.

CAPTCHA--the Completely Automated Public Turing test to tell Computers and Humans Apart--was designed to keep hackers from flooding Web sites with automated responses. By reading and then typing a distorted image of text designed to confuse OCR software, you prove that you're a real human being.

Vicarious claims a 95-percent success rate on reading and decoding individual letters in a CAPTCHA, and a 90-percent success rate on the full, two-word code.

The company is cracking CAPTCHA to show off its Recursive Cortical Network (RCN) technology, intended to mimic the human brain's neocortex (the part of the brain that manages language and complex thought).

According to a company announcement and Vicarious co-founder Dr. Dileep George, Vicarious is taking a whole new approach to artificial intelligence, with "a long term strategy for developing human level artificial intelligence" The process begins "with building a brain-like vision system."

Fortunately, Vicarious isn't planning to hack websites with their AI program. Potential commercial applications include medical analysis, image search, and robotics, but the company warns that any practical application is "still many years away."

So why the big announcement about CAPTCHA? According to George, "Modern CAPTCHAs provide a snapshot of the challenges of visual perception, and solving those in a general way required us to understand how the brain does it." Vicarious sees cracking CAPTCHA as a public demonstration of the software's capabilities. And a great opportunity to get some exposure.

Numai americanii au nevoie de AI pentru a sparge recaptcha-uri.

Kelvin@SV nu foloseste AI si tot are o rata de 60-70%.
