Researchers Dare AI Experts To Crack New GOTCHA Password Scheme

alphadogg writes "If you can't tell the difference between an inkblot that looks more like 'body builder lady with mustache and goofy in the center' than 'large steroid insect with big eyes,' then you can't crack passwords protected via a new scheme created by computer scientists that they've dubbed GOTCHA. GOTCHA, a snappy acronym for the decidedly less snappy Generating panOptic Turing Tests to Tell Computers and Humans Apart, is aimed at stymying hackers from using computers to figure out passwords, which are all too often easy to guess. GOTCHA, like its ubiquitous cousin CAPTCHA, relies on visual cues that typically only a human can appreciate. The researchers don't think that computers can solve the puzzles and have issued a challenge to fellow security researchers to use artificial intelligence to try to do so. You can find the GOTCHA Challenge here."

    It may or may not be uncrackable. Woot. But it certainly is untenable, unwieldy, and unimplementable. I've got to generate 6+ random-ish images, assign descriptions, and then at some point in the future re-match them? Why not have me generate a one-time pad at the length needed and ask me to remember that?

    Carrying around your password in your wallet is probably safe enough for most people. People carry money, credit cards, all kinds of valuable things in their wallet. Probably safer than using an insecure password.
