Sometimes it feels like it would be easier to translate hieroglyphics than try and determine what garbled text lies in a CAPTCHA box. We've all been annoyed by it, yet the reason it exists is to keep the spam bots from ruining our online playgrounds. Still, does it have to be so difficult? Perhaps not -- Google is introducing an easier method to prove you're a human called "No CATCHA reCAPTCHA." A quick history lesson is in order here. Like CAPTCHA, the Google-owned reCAPTCHA user-dialogue system tasks website visitors with typing in a pair of words that appear onscreen. What's unique about it... Read more...
Well, this isn’t good news (or else it’s awesome news, depending on how you look at it): An artificial intelligence software startup called Vicarious says that it can “reliably” (which is to say, 90% of the time) defeat text-based CAPTCHAs, those jumbled words and phrases that you have to decipher to prove that you’re a human online. This includes Google’s reCAPTCHA as well as those from Yahoo!, PayPal, Captcha.com, and more. Vicarious asserts that because of this, its software obviates CAPTCHAs as a Turing test, which sorts out who is a human and who is an AI... Read more...
As the Internet has grown up before our very eyes, a bevy of security protocols have taken shape to protect its users from ill-willed computers and those who program them. It may sound a bit dystopian, but Google has been one of the companies on a mission to make security easier and more foolproof for the masses. As it goes, CAPTCHAs have become commonplace on the web, typically used on ticketing services and sign-up pages to ensure that bots aren't buying or creating accounts en masse. As Google states: "Over the last few years advances in artificial intelligence have reduced the gap between human... Read more...
Few things on the Internet are both as necessary and annoying as CAPTCHAs, but it’s difficult to otherwise verify that a human being is attempting to access a site or send information. There have been and continue to be plenty of methods to improve CAPTCHAs, including an oddball empathy-based version, a twisted image that requires the user to drag sliders around to re-orient the image, taking the two-birds-with-one-stone approach of combining ads and CAPTCHAs, and more. One company that has developed a novel idea is AreYouAHuman, which offers a game-based verification system called PlayThru.... Read more...
Have you ever found yourself caught in a Captcha loop? It's where you do your best to decipher strings of text that sometimes look like a bunch of hieroglyphics, only to get it wrong over and over again until finally, you punch in the correct characters and are granted to access to a site you're now too frustrated to visit. Even more annoying is if you lose out on concert tickets because you couldn't figure out the code. Ticketmaster has long used Captcha to keep the bots at bay, which try to purchase large numbers of tickets that can later be scalped. Unfortunately, it slows down the process of... Read more...
The quest for a bullet-proof but human-usable CAPTCHA continues. A couple of months ago, we talked about a CAPTCHA implementation that relies on human empathy to bypass, but for a couple of reasons, it might not be ideal for a lot of people. Now, the folks at Minteye have given us yet another option: slide-to-fit. The idea is simple, and so is its usage. The user is presented with a nonsensical, twisted image. With a sliding bar, they can untwist the image so that it looks normal, at which point they'll be flagged as human and permitted to continue. As long as the basic premise is understood, this...

Love 'em or hate 'em, CAPTCHAs remain one of the most valuable tools for website owners to help keep comment spam to a minimum. While figuring out exactly what a CAPTCHA is trying to tell you can be frustrating as a user, the alternative is to peruse a comments section littered with spam, scams and other garbage. That's not to say that the CAPTCHA idea is perfect, however, because it certainly isn't. Simple CAPTCHA's can be easily broken through by bots, and if you tweak the settings too much, it suddenly becomes a real chore to those legit users who have to use them. But if you can easily understand... Read more...
After all these years, we're still trying to find the perfect CAPTCHA technique, something that will protect against automated system signups, but still be easy and not annoying for humans. Google has just released a report on what we can only hope is a step in that direction, which they call image orientation CAPTCHA. CAPTCHA (or "Completely Automated Public Turing Test to Tell Computers and Humans Apart") is used to prevent automated computer systems from signing up at sites or posting comments. The report, called "What's Up CAPTCHA?" (.PDF) outlines a new version, which uses image orientation,... Read more...
There's an old saying that if you gave a million monkeys a million typewriters and at least a million years, eventually they'd type the Collected Works of Shakespeare. It's  a way to illustrate a slim, but not infinitely impossible likelihood of anything. Researchers at Carnegie Mellon University have decided to try to use a similar vast but unfocused pool of available typing skills to digitize books- they're using the "CAPTCHA" test on websites to decipher printed words from important books and digitize them.  Researchers estimate that about 60 million of those nonsensical jumbles...
