Google Can Now Tell You’re Not a Robot With Just One Click

On Wednesday, Google announced that many of its “Captchas”the squiggled text tests designed to weed out automated spambots will be reduced to nothing more than a single checkbox next to the statement “I’m not a robot.” No more typing in distorted words or numbers; Google says it can, in many cases, tell the difference between a person or an automated program simply by tracking clues that don’t involve any user interaction.
