Digital rights management of content when content is a future live event

a technology for managing content rights and live events, applied in the direction of recording signal processing, instruments, television systems, etc., can solve the problems of not providing any mechanism to prevent legitimate users from obtaining clear documents, using and redistributing them in violation of content owners' intellectual property, and rendering applications such as browsers not trusted systems

Benefits of technology

The invention is a system that manages the use of digital content based on the user's rights to use it. The system includes an access list of trusted users, a device that associates content with this list, and a licensing device that issues a license to a user. The licensing device checks the access list to determine if the user is a member of the trusted community and issues a license for use of the digital content. If the user is not a member, the licensing device has a process to handle license requests from users who are not currently members of the trusted community. This system enables secure and controlled use of digital content.

Problems solved by technology

One of the most important issues impeding the widespread distribution of digital works via electronic means, and the Internet in particular, is the current lack of protection of intellectual property rights of content owners during the distribution and the usage of the digital content.
Clearly, the secure container approach provides a solution to protecting the document during delivery over insecure channels, but does not provide any mechanism to prevent legitimate users from obtaining the clear document and then using and redistributing it in violation of content owners' intellectual property.
While building tamper-proof trusted systems is a real challenge to existing technologies, current market trends suggest that open and untrusted systems such as PC and workstations using browsers to access the Web, will be the dominant systems used to access digital works.
In this sense, existing computing environments such as PCs and workstations equipped with popular operating systems (e.g., Windows™, Linux™, and UNIX) and rendering applications such as browsers are not trusted systems and cannot be made trusted without significantly altering their architectures.
Of course, alteration of the architecture defeats a primary purpose of the Web, i.e. flexibility and compatibility.

Embodiment Construction

[0030]The phrase “digital work” as used herein refers to any type of element having content in computer readable form. “Content” as used herein refers to the viewable or otherwise usable portion of a digital work. The phrase “usage rights” refers to manners of use which define permissions granted to a user of an existing digital work or a digital work to be created in the future with respect to use, access, distribution, and the like of the content of the work. In addition, one or more conditions may be specified which must be satisfied before the manners of use may be exercised.

[0031]A DRM system can be utilized to specify and enforce usage rights for items, such as digital content, goods or services. FIG. 1 illustrates a DRM system 10 that can be used to distribute digital content. DRM system 10 includes a user activation device, in the form of activation server 20, that issues public and private key pairs to content users in a protected fashion, as is well known. Typically, when ...

Abstract

A system for managing use of digital content within a trusted community. An access list defines the trusted community. License requests for use of content made from outside the trusted community are handled in accordance with a license request policy process.
