Disclosed is a system and method for super-distribution of rights-protected digital content. A first terminal offers digital content to a second terminal, using a unique content identifier to identify the content in the request. The second terminal requests information regarding the content from a service provider platform. The content information request includes a terminal type identifier for the second terminal. The service provider platform obtains format capabilities information for the second terminal from a terminal capabilities database, and selects a format type for the content using the format capabilities information. The service provider platform obtains a content object in the selected format type from a content storage database. The service provider platform then delivers the content object in the selected format to the second terminal.

Use of rights-managed content is enabled by a digital license that includes the identity of the licensee. The licensee redistributes the content by sending a package containing the content and the license to another party. That other party obtains a license to use the content by contacting a license server, and preferably pays a fee for this license. During the contact with the license server, the licensee's identifying information is uploaded to the license server, which allows the license server to determine who distributed the content to the other party. The license server can use this information to reward the original licensee for having redistributed the content.

Provided is an apparatus and method of securely moving security data. An apparatus for securely moving security stored in a first apparatus to a second apparatus, includes a status setting unit which set status information of the security data to a disabled state; a data providing unit which creates a copy of the security data and determines whether the created copy can be transmitted to the second apparatus; and a data deleting unit which deletes the security data when the copy is completely transmitted.
摘要:
A method for distributing content in a communications network including obtaining (210) encrypted content, for example, from a content provider or from another subscriber terminal, obtaining (220) a rights object for the content, and in some embodiments obtaining an encrypted token based on the identity of the subscriber terminal obtaining the rights object, maintaining (230) a relation between the content and identity of the subscriber obtaining the rights object, and tracking (240) distribution of the content by the subscriber terminal that obtained the rights object in the content.
摘要:
A technique for content redistribution. Digital content is packaged, and the package is associated with a first license that permits usage of the content on a first device. The first license also specifies the conditions upon which the content may be redistributed and licensed for use on a second device. When a content package is sent to the second device, the second device engages in a re-licensing transaction to obtain a second license that permits use of the content on the second device. Creation of the second license takes place according to conditions specified in the first license. For example, these conditions may specify a price for the second license, and/or a requirement that a portion of the purchase price be paid back to the owner of the first license, and/or a requirement that the first license be revoked upon creation of the second license.
摘要:
A descriptive data structure provides an abstract representation of a rights management data structure such as a secure container. The abstract representation may describe, for example, the layout of the rights management data structure. It can also provide metadata describing or defining other characteristics of rights management data structure use and/or processing. For example, the descriptive data structure can provide integrity constraints that provide a way to state rules about associated information. The abstract representation can be used to create rights management data structures that are interoperable and compatible with one another. This arrangement preserves flexibility and ease of use without compromising security.

A distributed computer system employs a license management system to account for software product usage. A management policy having a variety of alternative styles and contexts is provided. Each licensed program upon start-up makes a call to a license server to check on whether usage is permitted, and the license server checks a database of the licenses, called product use authorizations, that it administers. If the particular use requested is permitted, a grant is returned to the requesting user node. The product use authorization is structured to define a license management policy allowing a variety of license alternatives by values called "style", "context", "duration" and "usage requirements determination method". The license administration may be delegated by the license server to a subsection of the organization, by creating another license management facility duplicating the main facility. The license server must receive a license document (a product use authorization) from an issuer of licenses, where a license document generator is provided. A mechanism is provided for one user node to make a call to use a software product located on another user node; this is referred to as a "calling card", by which a user node obtains permission to make a procedure call to use a program on another node.

A Document Card (DocuCard) for storing documents and which is content revealing. The DocuCard is a transportable unit having a nonvolatile storage means for storing information in a digital form, a control processor for processing user initiated functions; an I/O port for interfacing to external devices for reading and writing digital information, and a user interface for allowing a user to directly interact with the DocuCard. The user interface on the DocuCard includes a display for displaying lists of functions and documents and information responsive to user invoked functions and a user input portion for allowing a user to traverse the lists of functions and documents, as well as information generated responsive to an invoked function. The control processor of the present invention include features for controlling access to documents stored therein.
