Abstract

The present invention provides systems and methods for transferring electronic information from one location to another such that only one original work exists at a given time. The methods and systems of the present invention allow distribution of originals without requiring a registration authority or other entity to vouch for what constitutes an “original” piece of information, thus reducing (or eliminating entirely) the need to centrally record changes in ownership each time originals change hands.

Claims

1. A method of distributing a first original electronic work from a sender'"'"'s site to a receiver'"'"'s site, the first original electronic work having a securely and persistently associated first electronic attribute indicating that it is an original, the method comprising:

establishing communication, by the sender'"'"'s site, between the sender'"'"'s site and the receiver'"'"'s site;

sending, from the sender'"'"'s site to the receiver'"'"'s site, first authentication information certifying at least one aspect of the sender'"'"'s site;

receiving, at the senders'"'"' site from the receiver'"'"'s site, second authentication information certifying at least one aspect of the receiver'"'"'s site;

creating, by the sender'"'"'s site, a first copy of the first original electronic work and securely and persistently associating with the first copy a second electronic attribute indicating that it is a copy;

transmitting, from the sender'"'"'s site, the first copy to the receiver'"'"'s site;

receiving, at the sender'"'"'s site from the receiver'"'"'s site, a first acknowledgement indicating receipt of the first copy by the receiver'"'"'s site, and, responsive thereto, changing the first electronic attribute to indicate that it is a copy, thereby creating a second copy of the first original electronic work; and

sending, from the sender'"'"'s site to the receiver'"'"'s site, an authorization authorizing the receiver'"'"'s site to change the second electronic attribute to indicate that it is an original, thereby creating a second original electronic work,

wherein the first and second copies are prevented from being successfully passed off as original electronic works and the second electronic attribute associated with the first copy of the electronic work is configured to be authenticated independently by the receiver'"'"'s site after receipt of the first copy by the receiver'"'"'s site.

2. A method as in claim 1, further comprising:

receiving, at the sender'"'"'s site from the receiver'"'"'s site, a second acknowledgement indicating that the receiver'"'"'s site successfully changed the second electronic attribute associated with the first copy to indicate that it is an original.

3. The method of claim 1, wherein the senders site comprises a first protected computing environment operable to substantially impede users of the sender'"'"'s site from successfully tampering with the first and second electronic attributes.

4. The method of claim 3, wherein the step of sending first authentication information includes sending information regarding the presence or nature of the first protected computing environment at the sender'"'"'s site.

5. The method of claim 1, wherein the step of receiving second authentication information includes receiving information regarding the presence or nature of a second protected computing environment at the receiver'"'"'s site operable to substantially impede users of the receiver'"'"'s site from successfully tampering with the first and second electronic attributes.

6. The method of claim 2, further comprising:

notifying, by the sender'"'"'s site, a system administrator if the second acknowledgement is not received by the sender'"'"'s site within a predetermined period of time.

7. The method of claim 1, wherein the original electronic work is selected from the group consisting of:

ebooks, music, documents, bearer bonds, currency, movies, and software.

8. The method of claim 1, wherein at most one electronic work with an electronic attribute indicating that it is an original exists at the sender'"'"'s site and the receiver'"'"'s site during the steps of the method.

9. The method of claim 1, wherein one or more types of available use of the first and second copies by the sender'"'"'s and/or receiver'"'"'s sites is limited from one or more types of available use of original electronic works.

10. The method of claim 1, wherein the electronic work is a digital certificate.

11. A computer-readable medium storing instructions that, when executed by a processor included in a sender'"'"'s site, are configured to cause the processor to perform a method for sending an original electronic work from the sender'"'"'s site to a receiver'"'"'s site, the method including:

establishing communication with the receiver'"'"'s site;

exchanging authentication information with the receiver'"'"'s site;

generating a first copy of a first original electronic work, and securely and persistently associating a first electronic attribute with the first copy indicating that it is a copy;

sending the first copy to the receiver'"'"'s site;

receiving a first acknowledgement from the receiver'"'"'s site, the first acknowledgement indicating the receipt of the first copy by the receiver'"'"'s site, and, responsive thereto, changing a second electronic attribute associated with the first original electronic work to indicate that it is a copy, thereby creating a second copy of the first original electronic work;

sending, by the sender'"'"'s site, an authorization to the receiver'"'"'s site authorizing and directing the receiver'"'"'s site to securely change the first electronic attribute associated with the first copy to indicate that it is an original, thereby creating a second original electronic work, wherein the first and second copies are prevented from being successfully passed off as original electronic works and the first electronic attribute associated with the first copy is configured to be authenticated independently by the receiver'"'"'s site after receipt of the first copy by the receiver'"'"'s site.

12. The computer-readable medium of claim 11 further storing instructions that, when executed by the processor included in the sender'"'"'s site, cause the processor to perform a method including:

receiving a second acknowledgement from the receiver'"'"'s site, the second acknowledgement indicating that the receiver'"'"'s site successfully changed the first electronic attribute associated with the first copy to indicate that it is an original.

13. The computer-readable medium of claim 11, wherein the processor comprises a protected computing environment being operable to substantially impede users of the sender'"'"'s site from successfully tampering with the first and second electronic attributes.

14. The computer-readable medium of claim 13, wherein the step of exchanging authentication information includes exchanging information regarding the presence or nature of the protected computing environment at the sender'"'"'s site and a protected computing environment at the receiver'"'"'s site.

15. The computer-readable medium of claim 11 further storing instructions that, when executed by the processor included in the sender'"'"'s site, cause the processor to perform a method for including:

receiving a second acknowledgement from the receiver'"'"'s site, the second acknowledgement indicating that the receiver'"'"'s site successfully changed the first electronic attribute associated with the first copy to indicate that it is an original; and

notifying a system administrator if the second acknowledgement is not received from the receiver'"'"'s site within a predetermined period of time.

16. The computer-readable medium of claim 11, wherein the original electronic work is selected from the group consisting of:

ebooks, music, documents, bearer bonds, currency, movies, and software.

17. The computer-readable medium of claim 11, wherein at most one electronic work with an electronic attribute indicating that it is an original exists at the sender'"'"'s site and the receiver'"'"'s site during the performance of the method.
