Google introduces simple "Are you a robot" captcha
It seems the days of having to squint to work out what the words mean, as you decipher your want to progress through a form, are numbered. Google have introduced a new captcha mechanism, called 'no captcha'.
A brief history of CAPTCHAs
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.
To counter this, last year we developed an Advanced Risk Analysis backend for reCAPTCHA that actively considers a user’s entire engagement with the CAPTCHA—before, during, and after—to determine whether that user is a human. This enables us to rely less on typing distorted text and, in turn, offer a better experience for users. We talked about this in our Valentine’s Day post earlier this year.
The new API is the next step in this steady evolution. Now, humans can just check the box and in most cases, they’re through the challenge.
Are you sure you’re not a robot?
However, CAPTCHAs aren't going away just yet. In cases when the risk analysis engine can't confidently predict whether a user is a human or an abusive agent, it will prompt a CAPTCHA to elicit more cues, increasing the number of security checkpoints to confirm the user is valid.
