Abstract: An augmented reality (AR) authentication method and system provides an AR environment that is presented on a display. The AR environment combines real-world object images captured by a camera with computer generated virtual icons. The virtual icons may be “mapped” to the real-world objects, whereupon the real-world objects take on the characteristics of the mapped images. During an authentication process, a user interacts with the AR environment by a variety of techniques to enter their passcode. Such interaction may include physically moving objects in the real-world so that such movement is reflected in the AR environment; controlling the “mapped” real-world objects through user interaction with the AR environment via an input device; and controlling the virtual icons through user interaction with the AR environment via the input device. Accordingly, if the user interacts with the AR environment in a manner that matches their previously “set” passcode the user is authenticated.
