Abstract
A device and method for securely rendering content on a gesture-enabled computing device includes initializing a secure execution environment on a processor graphics of the computing device. The computing device transfers view rendering code and associated state data to the secure execution environment. An initial view of the content is rendered by executing the view rendering code in the secure execution environment. A gesture is recognized, and an updated view of the content is rendered in the secure execution environment in response to the gesture. The gesture may include a touch gesture recognized on a touch screen, or a physical gesture of the user recognized by a camera. After the updated view of the content is rendered, the main processor of the computing device may receive updated view data from the secure execution environment.
