Patent Title: System for delaying the activation of inactivity security mechanisms by allowing an alternate input of a multimedia data processing system

Abstract: A data processing system has a security mechanism to lock up a secured input device, such as a keyboard, after the secured input device has been inactive or unused after a predetermined event, such as the expiration of a period of time, has occurred. Multimedia input devices are used to provide alternatives to the secured input device. Activation of the security mechanism is delayed when using an alternate or multimedia input device by providing an emulating input to the security mechanism. The emulating input simulates an input produced by the secured input device. The emulating input is produced before the predetermined event occurs if the alternate input device has produced an input. Furthermore, some alternate input devices, such as voice recognition systems, have general input properties and provide non-user inputs, such as background noise. Therefore, user inputs are distinguished from non-user inputs so that non-user inputs do not delay activation of the security mechanism.
