Method, system and program product for a window level security screen-saver

Screensaver functionality is provided at the individual window level. A windows security module monitors the windows displayed by the computer to detect when a window becomes inactive in the display, for example by the user clicking and working within another window in the display. Upon becoming inactive, the windows security module overrides the application data being sent to a secured window and displays a predetermined screensaver-type image in its place, thereby hiding sensitive information from being displayed by the window during periods of inactivity. The windows security module can implement any user selected security type to hide or obscure the windows content such as blanking the individual window, displaying a text message or other graphic in the window, or minimizing the individual window upon becoming inactive. A time delay can also be set to delay the assertion of the security feature until a specified time following the window becoming inactive.
