Abstract: A system and method for enforcing rights specifying manners of use of an item, include specifying by a recipient of an item a first rights expression indicating at least on of a desired manner of use of the item by the recipient and a condition of use of the item by the recipient; associating the rights expression with the item; and supplying the item to the recipient based on satisfaction of at least one of the desired manner of use of the item by the recipient and the condition of use of the item by the recipient.

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.

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.

Abstract: A method and apparatus for managing the transfer of rights associated with items from a rights supplier to a rights consumer. A set of rights is associated with an item and includes meta-rights specifying derivable rights that can be derived therefrom by the rights consumer. The set of rights is transferred, in the form of a license to the item, from the rights supplier to the rights consumer. If it is determined that the rights consumer is entitled to derive the derivable rights specified by the meta-rights, the derivable rights are derived and a license including the derived rights is generated with the rights consumer designated as a principal.

Abstract: A rights management system including one or more consequential rights associated with digital content, and specifying a manner of use of the digital content, a right management module that enforces the rights permitting use of the digital content in accordance with the rights upon occurrence of a consequential event. The consequential event is based on another usage right. In one embodiment, the consequential event is the exercise, expiration, or possession of another usage right.

Abstract: A system and method for managing use of items having usage rights associated therewith. In one embodiment, the method includes receiving a request for a license associated with an item on behalf of a license requesting user, the license requesting user having an associated identification mechanism. The method also includes determining whether the identification mechanism associated to the license requesting user is in an access list associated with the item, the access list having identification mechanisms associated with authorized users. The method further includes issuing the license associated with the item to the license requesting user upon determining that the identification mechanism associated to the license requesting user is in the access list.

Abstract: A method and apparatus for verifying data integrity. A compression parameter, such as the average code length of compressed data, is obtained. The parameter is transmitted to a recipient of the data to permit the recipient to again determine the parameter and compare the value of the parameter to the originally determined value. If the value of the parameter has changed, the data may have been modified or otherwise manipulated.

The system also includes a license server adapted to generate a license associate with the content from the rights label before the content is generated, the license including the distribution key encrypted with the public key, and a content distributor adapted to distribute the license before the content is generated.

Abstract: A method and apparatus for managing access to resources that integrates both authorization and protection for a wide range of resources. The rights to access a protected resource are based on conditions. Conditions are associated with both resource the resource and the state of the resource to thereby protect the resource at various stages during its life cycle. Conditions that are associated with the entire life cycle of the protected resource can be expressed by use of a grammar including data structures, sets of rules or a language.

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.

Abstract: Usage rights to digital content are dynamically assigned. Various dynamic conditions are monitored and the usage rights are adjusted in a predetermined manner based on the status of dynamic conditions. The dynamic conditions include the time of day, the load on a server or network, or the like. The resolution of an image can be determined based on the conditions and the image can be rendered using subband decomposition techniques to permit variable resolution images to be constructed on the fly.
