However, the password input at the time of logon cannot be performed by handwriting input, and an external connection is required. It is necessary to carry out using the keyboard or the virtual input screen 8. When the password input screen is displayed, a WM_WTSSESSION_CHANGE message is transmitted from the OS to the control software 10, and the control software 10 recognizes that it is in the password input state.

  When the external keyboard is not connected to the information processing apparatus 1, when the control software 10 recognizes that the external keyboard is not connected and the password input screen is activated, the virtual input screen is displayed. 8 is activated and displayed on the display 3. At this time, even if the user performs a predetermined operation so that the virtual input screen 8 is not displayed, the virtual input screen 8 is necessary for password input. The virtual input screen 8 is automatically redisplayed on the display 3.

  When the password input is completed and the user's logon process is executed, the control software 10 recognizes that the password input state has ended, and the virtual input screen 8 is automatically hidden. Thereafter, if necessary, the user can re-display the virtual input screen 8 by performing a predetermined process.

  When the password input screen is activated and the virtual input screen 8 is displayed on the display 3 in a state where the external keyboard is not connected to the information processing apparatus 1, the external keyboard is connected to the information processing apparatus 1. Then, the virtual input screen 8 remains displayed on the display 3, but when the user hides the virtual input screen 8, the virtual input screen 8 is not redisplayed unlike the above. In this case, the user may input a password using an external keyboard.

  In the state where the external keyboard is connected to the information processing apparatus 1, even if the state where the external keyboard is connected is recognized by the control software 10 and the password input screen is activated, the virtual input screen is displayed. 8 is not displayed on the display 3. At this time, even if the user performs a predetermined process to display the virtual input screen 8, the virtual input screen 8 cannot be displayed by the control operation of the control software 10.

  At this time, when the external keyboard is removed from the USB port in the state before the password input state is completed, the virtual input screen 8 is automatically displayed on the display 3.

  Since the virtual input screen 8 is always displayed on the forefront of the display 3, it covers other screens displayed on the display 3, but the virtual input screen 8 is displayed only when necessary as described above. By displaying on the display 3, the operability for the user is improved, and the usability can be improved.

  The virtual input screen 8 is activated by calling a predetermined executable file by the first software 9, and a predetermined digital signature is applied to the executable file. When calling, the digital signature is always confirmed and activated. Therefore, even if there is another file in the information processing apparatus 1 that has the same file name as the executable file and is not subjected to a predetermined digital signature, the other file is not displayed when the virtual input screen 8 is called. It is never called and the security is improved.
