Today the Google has announced that everyone unhappy with CAPTCHAs should be happy. Of course it did not announce this, but the new CAPTCHA known service is designed to block automated connections to malicious users using bots. 
The good news is that you will no longer have to try to guess what the deformed letters and numbers are. Google says it can, in many cases, recognize the difference between a person or an automated program simply by watching the user's movements. It will then be able to separate a person from a machine in the way the mouse moves.
"For most users, this dramatically simplifies the experience," reports Vinay Shet, Admin του προϊόντος της ομάδας Captcha της Google. “Μπορείτε να λύσετε το catptcha χωρίς να χρειάζεται να το λύσετε.”
Google's new captcha, which requires just one click in a box.

So instead of the traditional distorted words, “ReCaptcha” of Google will examine messages that each user gives unintentionally: IP addresses and cookies they will provide proof that the user is real as Google will also remember them from somewhere else on the internet. Shet also mentioned that the tiny movements of the user's mouse as they hover when approaching a box can help the company detect automated bots.
"All of this gives us a model for how a person behaves," says Shet. "It's a whole process that a bot can't get over." He adds that Google will use other variables that it will not disclose, so as not to help botmasters improve their software and undermine Google's filters.
In cases where a simple click does not work, a pop-up window will appear and will require users to decipher the same old distorted text.
For smartphones and tablets, Google has not yet developed the one-click captcha. Instead, it will show users a collection of pictures and will ask them to make distinctions that are difficult for bots to make.
