Network authentication apparatus, network authentication method, network authentication system, and network authentication program

A program comprising a network authentication program for causing a computer to execute

• a process of reading out device attribute information containing individual identification information of a cellular phone from the cellular phone inserted in the fitting portion of a cellular phone connection unit in/from which the cellular phone can be inserted/removed, and
• a process of sending out the readout device attribute information as authentication information to the digital network.

A network authentication system comprising:

• a network authentication apparatus which includes an IT terminal device which has a display unit and an input unit and is connected to a digital network, a cellular phone connection unit which is connected to the IT terminal device, includes a fitting portion in/from which a cellular phone can be inserted/removed, and connects the cellular phone inserted in the fitting portion to the IT terminal device, and a fixed telephone set connected to the IT terminal device, the IT terminal device reading out device attribute information containing individual identification information of the cellular phone from the cellular phone connected to the cellular phone connection unit and sending out the readout device attribute information as authentication information to the digital network;
• and
• a provider connected through the digital network and including an information storage unit which includes an individual information recording database and is connected to said network authentication apparatus.
