Google makes reCAPTCHA easier for humans
MANILA, Philippines - In a post over the weekend on the Google Onine Security Blog, Google announced an upgrade to its reCAPTCHA service to make it more adaptive. The result: a potentially easier time inputting secondary passcode information for human users, and harder reCAPTCHA entries for automated software.
CAPTCHA, which stands for "Completely Automated Public Turing test to tell Computers and Humans Apart," is a popular security test some websites use to distinguish human users from software.
Most people have likely used CAPTCHA services without knowing it. If you've ever put in your password, then went through a secondary process to distinguish words or numbers from one another, you've likely had an experience with CAPTCHA.
According to Vinay Shet, Product Manager at reCAPTCHA, the updated system "uses advanced risk analysis techniques, actively considering the user’s entire engagement with the CAPTCHA – before, during and after they interact with it."
While the announcement didn't explain the specifics, reCAPTCHA now has multiple CAPTCHA classes for different user types. reCAPTCHA will try to sort out beforehand if you're human, and makes it your codes much easier for you to solve if you are.
Automated software will get a different CAPTCHA puzzle from reCAPTCHA. It's one that's "considerably more difficult" so they don't bypass the security.
As an example, humans have an easier time solving CAPTCHA codes with numbers. The company's upgraded system makes it more likely that humans get numerical CAPTCHA codes, whereas automated attempts will likely never see a numerical CAPTCHA again.
The reCAPTCHA service was acquired by Google in 2009. - Rappler.com
