Abstract

An apparatus for displaying information received from a communication apparatus including a key information producing unit configured to produce key information used to authenticate the communication apparatus; a key information distributing unit configured to distribute the key information; an authentication information receiving unit configured to receive authentication information; an authenticating unit configured to authenticate the communication apparatus by verifying whether or not the authentication information was formed based upon the key information; and a display information receiving unit configured to receive display information from the authenticated communication apparatus, wherein the authenticated communication apparatus has a distribution range during reception of the key information such that the outputted key information can be acquired.

Claims

1. An apparatus for displaying information received from a communication apparatus, comprising:

a key information producing unit configured to produce key information used to authenticate said communication apparatus;

a key information distributing unit configured to distribute said key information;

an authentication information receiving unit configured to receive authentication information;

an authenticating unit configured to authenticate said communication apparatus by verifying whether or not said authentication information was formed based upon said key information; and

a display information receiving unit configured to receive display information from said authenticated communication apparatus,

wherein said authenticated communication apparatus has a distribution range during reception of said key information such that said outputted key information can be acquired.

2. The apparatus as claimed in claim 1, wherein said key information distributing unit is a display unit configured to display said key information, and the distribution range of said key information is such that said key information displayed on said display unit can be viewed.

3. The apparatus as claimed in claim 2, wherein said display unit converts said key information into a picture that can be displayed by said information display unit and superimposes said picture on an image of the display information.

4. An apparatus as claimed in claim 2, further comprising:

a display panel, wherein said display unit displays said key information on said display panel as at least one of a character or an image.

5. The apparatus as claimed in claim 1, wherein said key information distributing unit is a sound output unit configured to output sound for distributing said key information, and the distribution range of said key information is such that a sound outputted by said output unit can be heard.

6. The apparatus as claimed in claim 1, wherein said key information distributing unit is a transmitting unit configured to transmit said key information by infrared transmission, and the distribution range of said key information is such that the infrared rays transmitted by said transmitting unit can be received.

7. The apparatus as claimed in claim 2, wherein the communication apparatus authenticated by said authenticating unit is further equipped with a display information transmitting unit configured to transmit the display information displayed by said display unit.

8. The apparatus as claimed in claim 7, wherein said display information transmitting unit encrypts the display information to be transmitted such that the encrypted display information can be decoded by said communication apparatus.
