System and methods for secure transaction management and electronics rights protection
First Claim
1. A method comprising:
- creating an electronic document at a first user'"'"'s electronic appliance;
at the first user'"'"'s electronic appliance, securely associating first rule-based control information with the electronic document, the control information indicating that the electronic document may be used only by one or more designated users and only in one or more authorized ways, the control information being configured to be enforced by one or both of tamper-resistant software and hardware;
distributing the electronic document and the first control information to a second user'"'"'s electronic appliance, the second user'"'"'s electronic appliance comprising one or both of tamper-resistant software or hardware configured to govern use of electronic documents in accordance with the first control information;
determining that the second user is one of said one or more designated users;
receiving a request at the first user'"'"'s electronic appliance from the second user'"'"'s electronic appliance, the request seeking a modification to the first control information, and providing second control information that alters the one or more authorized ways in which the electronic document may be used; and
sending a modified set of control information based on the first and the second control information to the second user'"'"'s electronic appliance in response to the request;
wherein the second user'"'"'s electronic appliance is configured to securely enable the second user to make at least one use of the electronic document in accordance with the modified set of control information.

Abstract
The present invention provides systems and methods for secure transaction management and electronic rights protection. Electronic appliances such as computers equipped in accordance with the present invention help to ensure that information is accessed and used only in authorized ways, and maintain the integrity, availability, and/or confidentiality of the information. Such electronic appliances provide a distributed virtual distribution environment (VDE) that may enforce a secure chain of handling and control, for example, to control and/or meter or otherwise monitor use of electronically stored or disseminated information. Such a virtual distribution environment may be used to protect rights of various participants in electronic commerce and other electronic or electronic-facilitated transactions. Distributed and other operating systems, environments and architectures, such as, for example, those using tamper-resistant hardware-based processors, may establish security at each node. These techniques may be used to support an all-electronic information distribution, for example, utilizing the “electronic highway.”

15. A method performed at a first user'"'"'s electronic appliance, the method comprising:
-
creating an electronic document; associating rule-based first control information with the electronic document, the first control information indicating that the electronic document may be used only by one or more designated users and only in one or more authorized ways, the first control information being configured to be enforced by one or both of tamper-resistant software and hardware to govern use of the electronic document; determining that a second user is one of said one or more designated users; distributing the electronic document and the first control information to the second user'"'"'s electronic appliance; receiving a request from the second user'"'"'s electronic appliance, the request seeking a modification to the first control information and providing additional control information configured to authorize at least one additional use of the electronic document not authorized by the first control information; and sending a modified set of control information based on the first and the additional control information to the second user'"'"'s electronic appliance in response to the request. - View Dependent Claims (16, 17, 18, 19, 20, 21)
