摘要： 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.

摘要： 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. The method may include the step of adding new extensions to the rights expression system to allow processing of new rights expressions.
