`SYSTEM AND METHOD FOR MANAGING

`
`RELATED APPLICATION DATA
`
`This application is a continuation-in-part application of
`co-pending application Ser. No. 10/162,701 ?led on Jun. 6,
`2002, Which claims bene?t from US. provisional applica
`tions Ser. Nos. 60/331,624, 60/331,623, and 60/331,621 ?led
`on Nov. 20, 2001, and US. provisional applications Ser. Nos.
`60/296,113, 60/296,117, and 60/296,118 ?led on Jun. 7,
`2001, the entire disclosures of all of Which are hereby incor
`porated by reference herein.
`
`FIELD OF THE INVENTION
`
`The present invention generally relates to rights transfer
`and more particularly to a method, system and device for
`managing transfer of rights using shared state variables.
`
`20
`
`BACKGROUND OF THE INVENTION
`
`One of the most important issues impeding the Widespread
`distribution of digital Works (i.e. documents or other content
`in forms readable by computers), via electronic means, and
`the Internet in particular, is the current lack of ability to
`enforce the intellectual property rights of content oWners
`during the distribution and use of digital Works. Efforts to
`resolve this problem have been termed “Intellectual Property
`Rights Management” (“IPRM”), “Digital Property Rights
`Management” (“DPRM”), “Intellectual Property Manage
`ment” (“IPM”), “Rights Management” (“RM”), and “Elec
`tronic Copyright Management” (“ECM”), collectively
`referred to as “Digital Rights Management (DRM)” herein.
`There are a number of issues to be considered in effecting a
`DRM System. For example, authentication, authorization,
`accounting, payment and ?nancial clearing, rights speci?ca
`tion, rights veri?cation, rights enforcement, and document
`protection issues should be addressed. US. Pat. Nos. 5,530,
`235, 5,634,012, 5,715,403, 5,638,443, and 5,629,980, the
`disclosures of Which are incorporated herein by reference,
`disclose DRM systems addressing these issues.
`TWo basic DRM schemes have been employed, secure
`containers and trusted systems. A “secure container” (or sim
`ply an encrypted document) offers a Way to keep document
`contents encrypted until a set of authoriZation conditions are
`met and some copyright terms are honored (e. g., payment for
`use). After the various conditions and terms are veri?ed With
`the document provider, the document is released to the user in
`clear form. Commercial products such as CRYPTOLOPESTM
`and DIGIBOXESTM fall into this category. Clearly, the secure
`container approach provides a solution to protecting the
`document during delivery over insecure channels, but does
`not provide any mechanism to prevent legitimate users from
`obtaining the clear document and then using and redistribut
`ing it in violation of content oWners’ intellectual property.
`In the “trusted system” approach, the entire system is
`responsible for preventing u
