Abstract
A system is disclosed for a digital rights management system which enforces license rights by establishing an account domain of registered consumer devices which may each receive a decryption key to be used to decode digital content bought by any of the devices within the account domain. Such system further enables the decentralization of content sharing by establishing a network of trusted intermediate devices to manage licenses on end devices for a central rights provider.
