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."
