Zusammenfassung:In the present invention, a dummy layer generation and completion unit (1301) generates a dummy layer if a screen layer of a secure virtual computer (101) has been created. A display driver switch unit (1322) switches display control to the secure virtual computer (101) in order to cause a screen data combination unit (1331) to combine screen layers if at least one dummy layer has been generated, whereas the display driver switch unit (1322) switches display control to a non-secure virtual computer (102) in order to cause a screen data combination unit (1321) to combine the screen layers if a dummy layer has not been generated.
