Abstract
A device is configured to enter a stealth mode in response to a trigger and/or triggering event. The trigger/triggering event can be a voice command, a depression(s) of a button(s) or pattern of buttons on the device, a keyboard and/or softkey entry, entry of a pattern on the display of the device, a designated movement of the device, detection of an event, and/or lack of detection of an event. The device activates the stealth mode without any indication to the user of the device that the device is activating the stealth mode. The stealth mode operates concurrently with all other functions of the device. A virtual secure channel can be established that allows communication with the device without providing an indication that the device is communicating via the virtual secure channel. A token can be utilized for authentication and to discriminate be stealth and normal modes.
