Google Introduces New reCAPTCHA System : to find Human or Robot

As Google recently announced reCAPTCHA, this will protects the websites you love from spam and abuse. So, when you go online say, for some last-minute holiday shopping. You won't be competing with robots and abusive scripts to access sites.

Captcha, standing for completely automated public turing test to tell Computers and Humans Apart, is designed to prevent automated spamming of sites by setting this test, which people find easier than machines.

Google's ReCaptcha system introduces hard-to-read text from newspapers, books and other old sources such as maps.

On websites using this new API, a significant number of users will be able to securely and easily verify they’re human without actually having to solve a CAPTCHA. Instead, with just a single click, they’ll confirm they are not a robot.

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.

last year we developed an Advanced Risk Analysis backend for reCAPTCHA that actively considers a user’s entire engagement with the CAPTCHA before.

Many weird and wonderful alternatives to the unloved mangled-text CAPTCHA have been tried, ranging from videos and "games" to calculus-based CAPTCHAs. Google's reCAPTCHA at least serves some useful purpose in helping to digitize books.

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.

For mobile phones and tablets the tick-box test does not work on its own because there is no mouse. So users will be presented with an image and asked which of nine others is its closest match. Google says its new checks make sites safer from automated infiltration than before.
