First Claim
1. An information terminal device that reads character data including at least a character string from a server device on a communication line and displays the character data on a display screen,said information terminal device comprising:
- an option menu display module that displays on the display screen an option menu, which includes multiple options corresponding to multiple functions installed in said information terminal device in a selectable manner;
a general data display module that is activated by selection of a corresponding option in the option menu to enable a first function, which displays non-confidential character data as general data on the display screen in a selectable manner and, in response to selection of one of the displayed general data, displays content of the selected general data;
an operation unit that is operated to select one of the multiple options included in the option menu to activate a corresponding one of the multiple functions;
an operation detection module that detects operation of the operation unit; and
a confidential data display module that is not included as one option in the option menu but is activated by a specific series of operations of the operation unit in a preset order to enable a second function, which displays confidential character data as confidential data on the display screen in a selectable manner and, in response to selection of one of the displayed confidential data, displays content of the selected confidential data,wherein the operation detection module detects the specific series of operations of the operation unit in the preset order without displaying an operation-related window on the display screen.

Abstract
The information terminal device of the invention has a first function of displaying non-confidential data in a selectable manner on its display screen and, in response to the user'"'"'s selection of the non-confidential data, showing the details of the non-confidential data. The information terminal device also has a second function of displaying confidential data in a selectable manner and, in response to the user'"'"'s selection of the confidential data, showing the details of the confidential data. The first function is given as one normally selectable menu option and is activated by the user'"'"'s selection of the corresponding menu. The second function is, however, not given as a normally selectable menu option and is triggered only by the user'"'"'s series of operations of an operation unit in a preset sequence. No operation-related display appears on the display screen of the information terminal device during the user'"'"'s series of operations of the operation unit. The information terminal device of this configuration does not hint even the presence of confidential data to any third person and thus effectively prevents the third person from analyzing or decoding the data stored in the information terminal device and having illegal access to the confidential data. This arrangement of the invention desirably enables the safe handling of confidential data without the potential for leakage of the confidential data from the information terminal device.
