Abstract: A touch event processing method and a portable device implementing the same is provided for protecting a touch event occurring on a touch screen from hacking. Touch coordinates from a touch panel are first provided to the first operating system. It is then determined whether a function corresponding to the touch coordinates is to execute a security application. If so, a touch event processing right handover message is transmitted from the first operating system to the second, to hand over a right of processing a touch event that occurs on the touch panel to the second operating system.

Abstract: A method of processing touch events and an electronic device adapted to the method are provided. The electronic device includes: a touch screen; a processor electrically connected to the touch screen; a touch control circuit, electrically connected to the touch screen and the processor, the touch control circuit configured to create a touch event in response to a touch input detected on the touch screen; and a memory electrically connected to the processor. The processor is configured to execute at least one application stored in the memory, to determine attribute information of the executed application, to generate touch area information containing an attribute corresponding to at least part of the area of the touch screen and information regarding at least part of the area of the touch screen, based on the attribute information, and to provide the touch area information to the touch control circuit. The touch control circuit determines whether a touch event corresponding to the detected touch input is created, based on the touch area information.
