Paper [PDF] a new approach of Captchas, has been released by Google researchers. This new feature will be very useful instead of using captchas to confirm that user is not a spam and he is a human. This new feature is about to orient a picture into an upright-facing position. We can change the position of the given image, it is too better than entering captchas.

This method is too hard for humans too, as they have to adjust this one correctly.
