Abstract:
A digital rights management (DRM) system operates on a computing device when a user requests that a protected piece of digital content be rendered by the computer device in a particular manner. The DRM system has a license store, a license evaluator, and a state store. The license store stores digital licenses on the computing device. The license evaluator determines whether any licenses stored in the license store correspond to the requested digital content and whether any such corresponding licenses are valid, reviews license rules in each such valid license, and determining based on such reviewed license rules whether such license enables the requesting user to render the requested digital content in the manner sought. The state store maintains state information corresponding to each license in the license store, where the state information is created and updated by the license evaluator as necessary.
Abstract:
A digital content package includes encrypted digital content to be rendered in accordance with a corresponding digital license and is separate and apart from the license. The encrypted digital content is decrypt-able according to a decryption key (KD) obtained from the license. The package also includes a content/package ID that identifies one of the digital content and the package, and license acquisition information including a location of a license provider for providing the license.
Abstract:
To determine whether digital content can be released to an element such as a computer application or module, a scaled value representative of the relative security of the element is associated therewith, and the digital content has a corresponding digital license setting forth a security requirement. The security requirement is obtained from the digital license and the scaled value is obtained from the element, and the scaled value of the element is compared to the security requirement of the digital license to determine whether the scaled value satisfies the security requirement. The digital content is not released to the element if the scaled value does not satisfy the security requirement.
Abstract:
To obtain a digital license for rendering a piece of digital content, a license requester contacts a license provider and sends a license request. The license provider checks the license request for validity and negotiates with the license requestor terms and conditions for the requested license. The license provider generates the requested license and issues the generated license to the license requestor.
