`
`ABSTRACT
`
`The present invention provides systems and methods for
`secure transaction management and electronic rights protec(cid:173)
`tion. 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 elec(cid:173)
`tronically stored or disseminated information. Such a virtual
`distribution environment may be used to protect rights of
`various participants in electronic commerce and other elec(cid:173)
`tronic or electronic-facilitated transactions. Distributed and
`other operating systems, environments and architectures,
`such as, for example, those using tamper-resistant hardware(cid:173)
`based processors, may establish security at each node. These
`techniques may be used to support an all-electronic infor(cid:173)
`mation distribution, for example, utilizing the "electronic
`highway."
