  • Patent number: 9898715
    Abstract: System and methods for manipulating rights expressions for use in connection with a rights management system include one or more tokenized templates. Each tokenized template includes one or more rights expression language statements and one or more tokens associated with at least one of the rights expression language statements. Further, the tokens can be place holders for data items or rights expression elements. The system further includes a license template module that creates the tokenized templates, and a license instance creation module that replaces at least one of the tokens in one or more selected license templates with one or more of the data items or rights expression elements to generate a license instance. Additionally, the system includes a license instance analysis module having sub-modules for validating and interpreting license instances, and a data parsing module for extracting data from created license instances.

  • Publication number: 20140304177
    Abstract: A system, method and computer program product for a digital content player having a DRM agent to perform rights management operations on a digital content package, including loading rights management instructions to be executed by the digital content player, the rights management instructions being associated with the digital content package, executing the rights management instructions on the digital content player, and loading supporting licenses associated with the digital content package for processing by the DRM agent. The DRM agent deciding whether to permit the rights management operations requested by the rights management instructions. Further exemplary embodiments include systems, methods and computer program products for associating usage rights with digital content packages, managing of digital rights tokens, managing of digital content packages having predetermined broadcast dates, preserving of usage rights when content is transferred between DRM environments, and distributing content packages.

  • Publication number: 20110209223
    Abstract: Extensible grammar-based rights expression system for processing rights expressions including an interpreter with plug-in subcomponents, a validator, and a framework. In another embodiment, system includes a framework having an extensible architecture with extensibility points for adding extensions to the grammar, and an interpreter, the extensions defining semantics and syntax of new rights expressions. A method for processing rights expressions is also provided having the steps of registering plug-in components, making a programmatic call, finding and invoking appropriate plug-in components, evaluating the request against the grant, and returning an authorization result. In another embodiment, method includes the steps of providing an extensible grammar-based rights expression system having an extensible architecture with an interpreter, evaluating the request against the grant using the interpreter, and returning an authorization result.

  • Patent number: 7853531
    Abstract: Digital rights management method and system for items having usage rights. A first activation device defines a first trust zone. A first license device associated with the first trust zone generates an open license having usage rights associated with a first item. A second activation device defines a second trust zone and is adapted to issue a software package that enforces usage rights. A user device associated with the second trust zone is adapted to receive the software package from the second activation device, to receive the open license associated with the first item, and to use the first item in accordance with the open license. In addition, a method is provided for enforcing a license granting usage rights associated with a protected item, and for classifying a license, the license being an open license or a closed license.

  • Patent number: 7177843
    Abstract: A rights expression system and method for facilitating creation and/or modification of rights expressions in a rights expression language based on one or more schemas are provided. In one embodiment, the rights expression system comprises selectable layouts corresponding to a rights granting paradigm and comprises type selection components. Each type selection component is adapted to present REL terms and input components. The input components allow input of parameters required by the selected REL term. The rights expression system also includes a data engine that generates rights expressions in proper REL semantics defined by the one or more schemas based on the selected layout and parameter inputted. The type selection components and input components may be type selectors and input forms, respectively, that are implemented in a graphical user interface.
