The present invention provides systems and methods for electronic commerce
including secure transaction management and electronic rights protection.
Electronic appliances such as computers employed 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. Secure subsystems used with 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. Secure distributed and other
operating system environments and architectures, employing, for example,
secure semiconductor processing arrangements that may establish secure,
protected environments at each node. These techniques may be used to
support an end-to-end electronic information distribution capability that
may be used, for example, utilizing the "electronic highway."
