1. An information distribution system comprising:
- an information reading apparatus reading out data distributed from an information medium; and
an information display apparatus having an information acquisition unit for acquiring the data distributed from said information reading apparatus, a display for displaying the data acquired by said information acquisition unit, an authentication setting unit that accepts password settings for the data only when said information reading apparatus is in a directly-connected state with said information display apparatus using a connection cable and stops accepting password settings when said information reading apparatus is not in a directly-connected state with said information display apparatus using a connection cable, and a display limitation unit for imposing severer display limitations in cases where said information reading apparatus in an indirectly-connected state with said information display apparatus using connection cables between the information reading apparatus, an intermediary device, and the information display apparatus than in cases where said information reading apparatus is in a directly-connected state with said information display apparatus using a connection cable, wherein the display limitation unit requires password authentication with regard to the display of the data in cases where said information reading apparatus is not in a directly-connected state with said information display apparatus using a connection cable.

5. An information display apparatus comprising:
-
an information acquisition unit for acquiring the data distributed from external devices; a display for displaying the data acquired by said information acquisition unit; an authentication setting unit that accepts password settings for the data only when said external device is in a directly-connected state with said information display apparatus using a connection cable and stops accepting password settings when said external device is not in a directly-connected state with said information display apparatus using a connection cable; and a display limitation unit for imposing severer display limitations in cases where said external device is in an indirectly-connected state with said information display apparatus using connection cables between the external device, an intermediary device, and the information display apparatus than in cases where said external device is in a directly-connected state with information display apparatus using a connection cable, wherein the display limitation unit requires password authentication with regard to the display of the data in cases where said external device is not in a directly-connected state with said information display apparatus using a connection cable. - View Dependent Claims (9)

6. An information management method for managing data distributed from an information reading apparatus to an information display apparatus, comprising:
-
a step that the information reading apparatus reads out the data distributed from the information medium; a step that the information display apparatus acquires the data distributed from said information reading apparatus; a step that an authentication setting unit accepts password settings for the data only when said information reading apparatus is in a directly-connected state with said information display apparatus using a connection cable and stops accepting password settings when said information reading apparatus is not in a directly-connected state with said information display apparatus using a connection cable; and a step that the information display apparatus imposes severer display limitations in cases where said information reading apparatus is in an indirectly-connected state with said information display apparatus using connection cables between the information reading apparatus, an intermediary device, and the information display apparatus than in cases where said information reading apparatus is in a directly-connected state with said information display apparatus using a connection cable, wherein password authentication is required with regard to the display of the data in cases where said information reading apparatus is not in a directly-connected state with said information display apparatus using a connection cable. - View Dependent Claims (10)

7. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
-
accepting password settings for data acquired from an external device only when said external device is in a directly-connected state with said computer using a connection cable and stopping accepting password settings when said external device is not in a directly-connected state with said computer using a connection cable; imposing display limitations on the data acquired from the external device according to the state of physical connection between said external device and said computer; wherein the display limitations are severer in cases where said external device is in an indirectly-connected state with said computer using connection cables between the external device, an intermediary device, and the computer than in cases where said external device is in a directly-connected state with said computer using a cable; and requiring password authentication with regard to the display of the data in cases where said external device is not in a directly-connected state with said computer using a connection cable. - View Dependent Claims (11)
