Abstract

A system for controlling the distribution and use of digital works using digital tickets. In the present invention, a “digital ticket” 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 “generic ticket agent” which punches tickets. In some instances only the generic ticket agent is necessary. In other instances, punching by a “special ticket agent” residing on another repository may be needed.

Claims

1. A system for controlling the distribution and use of digital works comprising:

means for associating one or more usage rights with a digital work, said one or more usage rights specifying a manner of use indicating a particular manner of how said digital work may be used and at least one condition that must be satisfied in order to exercise the manner of use, at least one of said usage rights specifying a digital ticket, the possession of said digital ticket being a condition for that usage right;

a plurality of repositories for storing and exchanging digital works, each of said plurality of repositories comprising;

storage means for storing digital works, their associated usage rights, and digital tickets;

transaction processing means having a requester mode of operation for requesting access to a digital work, said request specifying a usage right, and a server mode of operation for processing requests to access said requested digital work based on said usage right specified in said request, the usage rights associated with said digital work, and digital tickets associated with said usage rights;

a generic ticket agent for punching digital tickets to indicate that an associated usage right has been exercised in accordance with a manner of use specified by the usage right;

a granting means for granting access to said digital work in accordance with the manner of use specified by said usage right if the requester possesses the digital ticket, wherein said granting means is not only a Boolean operator for filtering; and

a coupling means for coupling to another of said plurality of repositories across a communications medium.

2. The system as recited in claim 1 wherein a usage right specifies a special ticket agent for punching a specified digital ticket and said system is further comprised of one or more authorization repositories containing special ticket agents for punching digital tickets.

3. The system as recited in claim 1 wherein said digital ticket is comprised of a first timestamp part for indicating a time when said digital ticket was copied and a second timestamp part for indicating a time when said digital ticket was punched.

4. The system as recited in claim 3 wherein said generic ticket agent is further comprised of a means for determining if a digital ticket is valid and timestamping means for timestamping digital tickets when they are punched.

5. The system as recited in claim 4 wherein said means for determining if a digital ticket is valid is further comprised of a comparison means for comparing said first timestamp of said digital ticket with said second timestamp of said digital ticket so that if said first timestamp is later in time than said second timestamp, said digital ticket is determined to be valid.

6. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is a manner of rendering at least a portion of the digital work.

7. The system as recited in claim 6 wherein the manner of rendering is viewing at least a portion of the digital work.

8. The system as recited in claim 6 wherein the manner of rendering is printing at least a portion of the digital work.

9. The system as recited in claim 6 wherein the manner of rendering is playing at least a portion of the digital work.

10. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is copying at least a portion of the digital work.

11. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is transferring at least a portion of the digital work.

12. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is loaning a copy of at least a portion of the digital work for a predetermined period of time.

13. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is backing up at least a portion of the digital work.

14. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is restoring at least a portion of the digital work.

15. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is deleting at least a portion of the digital work.

16. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is requesting information about a digital work from a directory.

17. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is one of creating and renaming a folder containing the digital work.

18. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is extracting at least a portion of the digital work and creating a new digital work containing the extracted portion of said digital work.

19. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is using at least a portion of the digital work to create another digital work.

20. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is authorizing one or more usage rights relating to the digital work.

21. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is installing at least a portion of the digital work.

22. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is uninstalling at least a portion of the digital work.

23. The system as recited in claim 1 wherein the manner of use specified by the one or more usage rights is executing at least a portion of the digital work.
