Patent ID: 7340769

Claim:
A gateway for coupling a first private home network to a second different network, the gateway comprising: a first interface to communicate with the first private home network; a second different interface to communicate with the second different network, the second interface coupled to the first interface such that a network device located in the first private home network can exchange communications with the second network through the gateway; and localization circuitry integrated into the gateway and coupled to the first and second interfaces, the localization circuitry configured to: enroll the gateway in a network service by obtaining a credential from a provider device located outside the first private home network and then storing the credential on the gateway; receive a request from the network device located in the first private home network to enroll in the network service for controlling access to DRM content; verify that the requesting device is a member of the first private home network; and issue the credential to the network device when membership is verified, said issuing of the credential allowing the network device to demonstrate possession of the credential to obtain access to the DRM content that is both located outside the first private home network and associated with the network service; wherein the localization circuitry is further configured to verify membership by determining whether a first IP address for the network device belongs to a same IP address range as a second IP address for the gateway when both IP addresses identify a same subnet, and in addition to the address range verification, determining whether the network device has demonstrated knowledge of a same preshared credential; and wherein the network device is at least one selected from a group of a household device, a mobile device, a visitor device and a foreign device.
