Systems and methods for secure transaction management and electronic rights protection
View Patent ↗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.”
1. A method comprising:
executing end user content processing application software in one or more virtual machine environments that are executed by a host operating system of a computer system;
executing rights management software by the host operating system of the computer system, wherein the rights management software executes outside the one or more virtual machine environments in which the end user content processing application software is executing;
processing a protected piece of digital content using the end user content processing application software; and
using the rights management software to make a determination as to whether to allow the protected piece of digital content to be transmitted between the one or more virtual machine environments and a resource external to the one or more virtual machine environments, wherein the determination is based at least in part on one or more controls associated with the protected piece of digital content that define usage conditions for the protected piece of digital content.
2. The method of claim 1 , in which the end user content processing application software runs on an operating system that executes within the one or more virtual machine environments.
3. The method of claim 1 , in which the resource is a communication channel.
4. The method of claim 1 , in which the resource is a writable storage device.
5. The method of claim 1 , in which the one or more controls identify a list of users permitted to access or use the protected piece of digital content.
6. The method of claim 1 , in which the one or more controls include a requirement for an explicit permission to be granted from an originator of the protected piece of digital content.
7. The method of claim 1 , in which the one or more controls include a requirement for use of the protected piece of digital content to be reported to an originator of the protected piece of digital content.
8. The method of claim 1 , in which the one or more controls include a requirement for use of the protected piece of digital content to be reported to a clearinghouse.
9. The method of claim 1 , in which the one or more controls include a requirement for use of the protected piece of digital content to generate a notice to an originator of the protected piece of digital content, the notice including information supplied interactively by a person using the protected piece of digital content.
10. The method of claim 1 , in which the one or more controls include a requirement for information identifying a redistributor of the protected piece of digital content to be embedded in the protected piece of digital content prior to redistribution.
11. The method of claim 1 , in which the one or more controls include a budget limiting usage.
12. The method of claim 11 , in which the budget includes a limit involving a time of access.
13. The method of claim 1 , in which the protected piece of digital content comprises a document.
