A publishing user publishes digital content and issues to itself a corresponding digital publisher license to allow itself to render the published digital content. The publishing user is supplied with a publishing certificate from a digital rights management (DRM) server, where the publishing certificate allows the publishing user to so publish the digital content and to so issue the publisher license.

Issuing a publisher use license off-line in a digital rights management (DRM) system

A method for managing rights in digital content includes generating rights data for a piece of digital content and forming a piece of rights managed digital content by associating the rights data with the piece of digital content. The rights data includes parameters that govern the terms on which the content may be licensed, and may include a list of entities to which the content may be licensed, a respective set of one or more rights that each such entity has in the digital content, and any conditions that may be placed on those rights. A method for licensing rights managed digital content includes receiving a license request for a license to use the piece of rights managed digital content, where the license request includes such a signed rights label. The digital signature on the signed rights label is validated to determine whether a trusted entity issued the signed rights label. If a trusted entity issued the signed rights label, a license to use the piece of rights managed digital content in accordance with the rights data may be issued.

Systems and methods for issuing usage licenses for digital content and services

A licensor receives a request from a requestor including an identifier identifying the requestor and rights data associated with digital content, where the rights data lists at least one identifier and rights associated therewith. The licensor thereafter locates the identifier of the requestor in a directory, and locates in the directory based thereon an identifier of each group which the requestor is a member of. Each of the located requestor identifier and each located group identifier is compared to each identifier listed in the rights data to find a match, and a digital license to render the content is issued to the requestor with the rights associated with the matching identifier.

Publishing digital content within a defined universe such as an organization in accordance with a digital rights management (DRM) system

A first trusted component on a first computing device performs cryptography, evaluation, and enforcement and is tied thereto, and a first user-machine certificate associated with the first computing device is tied to a user. Correspondingly, a second trusted component on a second computing device performs cryptography, evaluation, and enforcement and is tied thereto, and a second user-machine certificate associated with the second computing device is also tied to the user. The first trusted component obtains the content for rendering on the first computing device by way of the first user-machine certificate and the license, and the second trusted component obtains the content for rendering on the second computing device by way of the second user-machine certificate and the same license.

Tying a digital license to a user and tying the user to multiple computing devices in a digital rights management (DRM) system

A Digital Rights Management (DRM) system has a plurality of DRM servers performing DRM functionality and an entering DRM-E server is enrolled into the system by an enrolling DRM-R server such that the entering DRM-E server is to be trusted within the system. The DRM-E server sends an enrollment request to the DRM-R server including a proffering identification and a public key (PU-E). The DRM-R server validates the proffering identification, and, if the request is to be honored, generates a digital enrollment certificate with (PU-E) for the DRM-E server to enroll such DRM-E server into the DRM system. The now-enrolled DRM-E server with the generated enrollment certificate is able to employ same to issue DRM documents within the DRM system.
