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. In a computer controlled system for the distribution of digital works including content and usage rights associated therewith, the usage rights specifying a manner of use of content of the digital works, the usage right also specifying a digital ticket that indicates a predetermined number of times that said usage right may be exercised, said system including at least one repository for enforcing usage rights, a method for controlling the number of times that a usage right associated with a digital work may be exercised, said method comprising the steps of:

a) storing said content, said usage right and said digital ticket in at least one storage;

b) receiving a request to access said digital work, said request specifying said usage right;

c) determining if said digital ticket for said usage right indicates that said usage right has been exercised said predetermined number of times;

d) if said digital ticket indicates that said usage right has been exercised said predetermined number of times, denying access to said digital work; and

e) if said digital ticket indicates that said usage right has not been exercised said predetermined number of times, granting access to said digital work and punching said digital ticket to indicate an instance of exercising said usage right.

7. The method of claim 1 wherein said usage right specifies a manner of rendering at least a portion of the digital work.

8. The method of claim 7 wherein the manner of rendering is viewing at least a portion of the digital work.

9. The method of claim 7 wherein the manner of rendering is printing at least a portion of the digital work.

10. The method of claim 7 wherein the manner of rendering is playing at least a portion of the digital work.

11. The method of claim 1, wherein said digital ticket is an instance of a digital work.
