According to Google would therefore be much easier to apply directly to users whether they are human or robot. This allows users to quickly register or use of a service, which also eliminates the annoyance of solving the captcha.

API

On the basis of the way in which the user handles were examined with the captcha or the user was a human. The new API is a development of this, which is looked at many factors which indicate that it is a human being. Where does the risk of insufficient evidence to make this decision will appear captcha again. In addition, the API also makes it possible to test other types of captcha's. The new API would now be used on various websites, including Snapchat, WordPress and Humble Bundle.
