8,104,075, "Trust management systems and methods," assigned to Intertrust.
Abstract
Systems and methods are presented for facilitating the configuration of a trust management framework for use in conjunction with web services, digital rights management systems, and/or other applications. A method for configuring a trust management framework involves providing graphical user interfaces (GUIs) to a user that prompt the user to define certain aspects of the trust management framework in a self-consistent manner. In one embodiment, a method comprises providing a roles GUI that prompts a user to define roles, a services GUI that prompts the user to define services corresponding to the roles, a principals GUI that prompts the user to define principals, including associating at least one of the roles with a principal, and a nodes GUI that presents role bindings for principals that are designated to function as nodes and that prompts the user to define interactions between nodes.

Abstract
A system for providing digital rights management (DRM) license is provided. The system includes a sink system requesting a license for content, a source system generating and providing a first rights token including binding information related to the license, in accordance with the request, and a rights mediator generating a second rights token that is usable in the sink system on the basis of the first rights token and transmitting the generated second rights token to the sink system. The sink system provides the license for the content on the basis of the second rights token. The first rights token includes binding information of principals that indicates use subjects related to the license, and binding information of principals that indicates use objects related to the license.
