  • Patent number: 7386513
    Abstract: A method, system, and computer program product for exercising rights based on determining trust in an issuance of a rights expression, including issuing rights expressions by a chain of servers, forming a chain of rights expressions issued from server to server and finally from the last server to a client, such that each of the rights expressions except the last includes a specification of rights for the next server to issue the rights in the next rights expression; determining whether or not each of the servers has a right to issue the respective rights expression; exercising by the client the rights expressed in the last rights expression as being trusted, if it is determined that each of the servers had a right to issue the respective rights expression; and not exercising by the client the rights expressed in the last rights expression as not being trusted, if it is determined that at least one of the servers did not have the right to issue the respective rights expression.

  • Patent number: 7359884
    Abstract: A system and method for processing a rights expression for association with an item for use in a system for controlling use of the item in accordance with the rights expression. A rights expression is specified in a conventional manner in an original format. An intermediate format of the rights expression is generated based on at least one of syntax information and semantics information associated with the original format. The rights expression specifies a manner of use of said item for enforcement on a device. The intermediate format can be converted to a device specific format or a simplified format for resource constrained devices to permit rights enforcement on various devices.

  • Patent number: 7152046
    Abstract: A method and system for managing the state of a protected resource in a system for granting access to a protected resource in accordance with usage rights. The usage rights include at least one state variable indicating a status of an associated protected resource. A message related to the state variable is transmitted from a resource control device to an interface framework. The resource control device is coupled to the resource to control use of the resource by enforcing the usage right. A state controller operative to track the value of the state variable is loaded into the framework and instructed to manipulate the value of the state variable in accordance with said message. For example, the message can be a query of the current value of the state variable.

  • Patent number: 7085741
    Abstract: A method and an apparatus for specifying and editing rights associated with a content includes a general model that comprehends rights specification at different levels of the content life cycle. The rights specification includes content association, and the protection of the content is a byproduct of the content and rights association. The general model includes a rights component, a conditions component, a rights offer component, and a rights label component. The rights offers specify the relationship between rights and conditions. The rights labels are collections of the offers.

  • Publication number: 20040015426
    Abstract: A system and method for creating a rights expression for association with an item for use in a system for controlling use of the item in accordance with the rights expression. Rights expression information indicating a manner of use of an item is expressed. A sound signal based representation of the rights expression information is then generated. The sound signal based representation is configured to be interpreted by an interpreter of a system for controlling use of the item to permit enforcement of the rights expression.
