House numbers on Google Street View can turn up as blobby, blurry things, so its engineers built a pretty crazy neural network to decipher them. Except this algorithm also turns out to be very very good at deciphering other blobby, blurry texts—like CAPTCHAs, which it cracks with 99 percent accuracy. Take that, human.
The CAPTCHA is a wonderful thing, but it’s not without its failings. And as hackers get better and better at cracking them, a team of CMU engineers are proposing an alternative: Inkblot tests.

Captcha is the worst, and Tickmaster’s particular strain of the virus is especially, well, impossible. It’s changing that, though, to a system that will hopefully be more friendly to actual people trying to use it. More »
Everybody wants a better Captcha. Trying to type in those distorted words can be a serious pain, and it’s becoming less and less of an impedance to ever-more-intelligent spam bots. The Civil Rights Captcha takes a different approach; you’ve got to have a little empathy. More »
More and more people understand that texting while driving is a bad idea, but RIM has just been granted a patent that would have smartphones step in before things get out of hand. Going beyond just filtering inbound messages like some motion-based lockdown apps, the BlackBerry maker’s invention also turns off the creation of any outbound messages as long as the phone is moving within a given speed range. The override for the lock is the dictionary definition of ironic, however: the technique makes owners type out the answer to a CAPTCHA challenge onscreen, encouraging the very problem it’s meant to stop. As much as we could still see the hassle being enough to deter some messaging-addicted drivers, we have a hunch that the miniscule hurdle is a primary reason why the 2009-era patent hasn’t found its way into a shipping BlackBerry. Maybe RIM should have chronic texters solve a Rubik’s Cube instead.
