A system for controlling use and distribution of digital works. In the present invention, the owner of a digital work attaches usage rights to that work. Usage rights are granted by the “owner”of a digital work to “buyers”of the digital work. The usage rights define how a digital work may be used and further distributed by the buyer. Each right has associated with it certain optional specifications which outline the conditions and fees upon which the right may be exercised. Digital works are stored in a repository. A repository will process each request to access a digital work by examining the corresponding usage rights. Digital work playback devices, coupled to the repository containing the work, are used to play, display or print the work. Access to digital works for the purposes of transporting between repositories (e.g. copying, borrowing or transfer) is carried out using a digital work transport protocol. Access to digital works for the purposes of replay by a digital work playback device (e.g. printing, displaying or executing) is carried out using a digital work playback protocol.
A system for secure distribution and control of digital works between repositories comprising: means for creating usage rights, each instance of a usage right representing a specific instance of how a digital work may be used or distributed; means for attaching a created set of usage rights to a dig
A system for secure distribution and control of digital works between repositories comprising: means for creating usage rights, each instance of a usage right representing a specific instance of how a digital work may be used or distributed; means for attaching a created set of usage rights to a digital work; a communication medium for coupling repositories to enable exchange of repository transaction messages; a plurality of general repositories for storing and securely exchanging digital works with attached usage rights, each of said general repositories comprising: a storage means for storing digital works and their attached usage rights; an identification certificate for indicating that the associated general repository is secure; an external interface for removably coupling to said communications medium; a session initiation transaction processing means for establishing a secure and trusted session with another repository, said session initiation transaction processing means using said identification certificate; a usage transaction processing means having a requester mode of operation for generating usage repository transaction messages to request access to digital works stored in another general repository, said usage repository transaction message specifying a usage right, said usage transaction processing means further having a server mode of operation for determining if a request for access to a digital work stored in said storage means may be granted, said request being granted only if the usage right specified in said request is attached to said digital work; and an input means coupled to said usage transaction processing means for enabling user created signals to cause generation of a usage repository transaction message to request access to digital works.
