System For Controlling The Distribution And Use Of Digital Works Using Digital Tickets

View page
US Patent:
6708157, Mar 16, 2004
Filed:
Feb 7, 2001
Appl. No.:
09/778001
Inventors:
Mark J. Stefik - Portola Valley CA
Peter L. T. Pirolli - El Cerrito CA
Assignee:
ContentGuard Holdings Inc. - Bethesda MD
International Classification:
G06F 1760
US Classification:
705 59, 705 51, 705 54, 705 1, 705 67, 707 9, 707 10, 380227, 380230, 380229, 380228, 380278
Abstract:
A system for controlling the distribution and use of digital works using digital tickets. In the present invention, a âdigital ticketâ is used to entitle the ticket holder to exercise some usage right with respect to a digital work. Usage rights are used to define how a digital work may be used or distributed. Each usage right may specify a digital ticket which must be present before the right may be exercised. Digital works are stored in repositories which enforce a digital works usage rights. Each repository has a âgeneric ticket agentâ which punches tickets. In some instances only the generic ticket agent is necessary. In other instances, punching by a âspecial ticket agentâ residing on another repository may be needed.

The usage rights specify a manner of use indicating one or more stated purposes for which the digital content can be at least one of used and distributed by an authorized party. The usage rights are associated with the digital content. Information is exchanged with a first repository for storing the digital content and the associated usage rights and for processing a usage transaction specifying the usage rights to determine if access to the digital content can be granted. Information is exchanged with a second repository for generating the usage transaction specifying the usage rights for requesting access to the digital content.
