1. A communication system comprising:
- an information providing unit configured to provide information data;
an information providing-side network configured to provide connectivity to the information providing unit, to restrict access to the information providing-side network, and to operate under a first security policy restricting access to the information providing-side network based on an authentication determination made from within the information providing-side network;
an information transmitter configured to obtain the information data by transmitting request data for requesting the information data to the information providing unit, and transmit obtained information data to a terminal;
an information transmitting-side network configured to provide connectivity to the information transmitter, to restrict access to the information transmitting-side network, and to operate under a second security policy restricting access to the information transmitting-side network based on an authentication determination made from within the information transmitting-side network; and
a transfer unit comprising an interface for each of the information transmitting-side network and the information providing-side network, the transfer unit configured to connect to each of the networks, determine whether or not transmitting-side data received via the information transmitting-side network is data transmitted from the information transmitter, and whether or not providing-side data received via the information providing-side network is data transmitted from the information providing unit, and transfer the transmitting-side data and the providing-side data based on determination results.

Abstract
A video data providing unit (10) connects to a restricted access providing-side VPN (20). A streaming server (60) connects to a restricted access transmitting-side VPN (50). A router (40) determines whether or not transmitting-side data such as request data or instruction data received via the transmitting-side VPN (50) is data that has been transmitted from the streaming server (60), and whether or not providing-side data such as video data received via the providing-side VPN (20) is data that has been transmitted from the information providing unit (10). The router 40 then transfers the transmitting-side data and providing-side data based on those determination results.

8. A transfer device comprising:
-
a first interface connected to an information providing-side network, wherein the information providing-side network is configured to provide connectivity to an information providing unit, to restrict access to the information providing-side network, and to operate under a first security policy restricting access to the information providing-side network based on an authentication determination made from within the information providing-side network; a second interface connected to an information transmitting-side network, wherein the information transmitting-side network is configured to provide connectivity to an information transmitter, to restrict access to the information transmitting-side network, and to operate under a second security policy restricting access to the information transmitting-side network based on an authentication determination made from within the information transmitting-side network, and the information transmitter obtains the information data by transmitting request data for requesting the information data to the information providing unit and transmitting obtained information data to a terminal; and a controller configured to determine whether or not transmitting-side data received via the information transmitting-side network is data transmitted from the information transmitter, determine whether or not providing-side data received via the information providing-side network is data transmitted from the information providing unit, and transfer the transmitting-side data and the providing-side data based on determination results.
