Digital rights are associated with a semi-unique node identifier obtained or calculated from characteristics of a mobile device attached to a consumer device, rather than with the node identifier of the consumer device itself. The user of the consumer device may access the digital rights management encrypted content (which may come from local persistent storage or a network) by attaching the mobile device to the consumer device. In this way, the rights can be associated with the node identifier of the mobile device, and the rights are thus usable for the consumer device to access the encrypted content.
