ABSTRACT:
An information processing apparatus and method for ensuring security when a virtual keyboard is used while an image displayed on a display is disclosed to the outside are provided. According to an embodiment of the present invention, it is determined whether or not a virtual keyboard is displayed on a display (S100). If a virtual keyboard is displayed, it is determined whether or not a target character input window onto which characters are input by using the virtual keyboard is a password input window (S101). If this window is the password input window, VRAM distribution is temporarily stopped (S102). With this operation, the distribution of the image stored in the VRAM (i.e., the image displayed on the display) is stopped while a virtual input device is displayed on the display and the target character input window is the password input window.
