CAPTCHAs are an unfortunate side effect of the internet. They're those irritating collection of numbers and letters morphed into some Surrealist dreck that leaves us guessing, and guessing, and guessing. Google wants to improve all of that with updates to reCAPTCHA, a one-click solution for telling websites that you are, in fact, a human being. Wouldn't abandoning those Dali-like distortions defeat the purpose of protecting websites from bots? Not really, Google says, because the old CAPTCHA system wasn't working that great anyways: While the new reCAPTCHA API may sound simple, there is a high degree of sophistication behind that modest checkbox. CAPTCHAs have long relied on the inability of robots to solve distorted text. However, our research recently showed that today's Artificial Intelligence technology can solve even the most difficult variant of distorted text at 99.8% accuracy. Thus distorted text, on its own, is no longer a dependable test. View the full article
CAPTCHA are a thorn in the side of web users. Those almost indecipherable string of letters and numbers that are meant to help websites determine that you are a human rather than a spambot often cause more frustration for users than anything else, and they have now been cracked. Vicarious, a California-based AI team, reveals that it has been able to develop algorithms that can successfully solve CAPTCHAs from the likes of Google, Yahoo and PayPal. The cracking of CAPTCHAs by machine is nothing all that new, but Vicarious is reporting an extremely high success rate -- the algorithm is successful in up to 90 percent of cases. The company goes as far as saying that "this advancement renders text-based CAPTCHAs no longer effective as a Turing test". The Turing test -- introduced by Alan Turing, one of the old-masters of computing -- was developed to test whether a computer could pass itself off as a human being. View the full article
