`
`FIELD OF THE INVENTION
`
`The present invention relates to the field of distribution
`and usage rights enforcement for digitally encoded works.
`BACKGROUND OF THE INVENTION
`
`A fundamental issue facing the publishing and informa-
`tion industries as they consider electronic publishing is how
`to prevent the unauthorized and unaccounted distribution or
`usage of electronically published materials. Electronically
`published materials are typically distributed in a digital form
`and recreated on a computer based system having the
`capability to recreate the materials. Audio and video
`recordings, software, books and multimedia works are all
`being electronically published. Companies in these indus-
`tries receive royalties for each accounted for delivery of the
`materials, e.g. the sale of an audio CD at a retail outlet. Any
`unaccounted distribution of a work results in an unpaid
`royalty (e.g. copying the audio recording CD to another
`digital medium
`The ease in which electronically published works can be
`“perfectly” reproduced and distributed is a major concern.
`The transmission of digital works over networks is com-
`monplace. One such widely used network is the Internet.
`The Internet is a widespread network facility by which
`computer users in many universities, corporations and gov-
`ernment entities communicate and trade ideas and informa-
`tion. Computer bulletin boards found on the Internet and
`commercial networks such as CompuServ and Prodigy
`allow for the posting and retrieving of digital information.
`Information services such as Dialog and LEXIS/NEXIS
`provide databases of current, information on a wide variety
`of topics. Another factor which will exacerbate the situation
`is the development and expansion of the National Informa-
`tion Infrastructure (the NII). It is anticipated that, as the NII
`grows, the transmission of digital works over networks will
`increase many times over. It would be desirable to utilize the
`NII for distribution of digital works without the fear of
`widespread unauthorized copying.
`The most straightforward way to curb unaccounted dis-
`tribution is to prevent unauthorized copying and transmis-
`sion. For existing materials that are distributed in digital
`form, various safeguards are used. In the case of software,
`copy protection schemes which limit the number of copies
`that can be made or which corrupt the output when copying
`is detected have been employed. Another scheme causes
`software to become disabled after a predetermined period of
`time has lapsed. A technique used for workstation based
`software is to require that a special hardware device must be
`present on the workstation in order for the software to run,
`e.g., see U.S. Pat. No. 4,932,054 entitled “Method and
`Apparatus for Protecting Computer Software Utilizing
`Coded Filter Network in Conjunction with an Active Coded
`Hardware Device.” Such devices are provided with the
`software and are commonly referred to as dongles.
`Yet another scheme is to distribute software, but which
`requires a “key” to enable it’s use. This is employed in
`distribution schemes where “demos” of the software are
`
`2
`arovided on a medium along with the entire product. The
`demos can be freely used, but in order to use the actual
`aroduct, the key must be purchased. These scheme do not
`iinder copying of the software once the key is initially
`aurchased.
`
`A system for ensuring that licenses are in place for using
`icensed products is described in PCT Publication WO
`93/01550 to Griswold entitled “License Management Sys-
`em and Method.” The licensed product may be any elec-
`ronically published work but is most effective for use with
`works that are used for extended periods of time such as
`software programs. Griswold requires that the licensed prod-
`uct contain software to invoke a license check monitor at
`nredetermined time intervals. The license check monitor
`generates request datagrams which identify the licensee. The
`request datagrams are sent to a license control system over
`an appropriate communication facility. The license control
`system then checks the datagram to determine if the data-
`gram is from a valid licensee. The license control system
`then sends a reply datagram to the license check monitor
`indicating denial or approval of usage. The license control
`system will deny usage in the event that request datagrams
`go unanswered after a predetermined period of time (which
`may indicate an unauthorized attempt to use the licensed
`product).
`In this system, usage is managed at a central
`location by the response datagrams. So for example if
`license fees have not been paid, access to the licensed
`product is terminated.
`It is argued by Griswold that the described system is
`advantageous because it can be implemented entirely in
`software. However, the system described by Griswold has
`limitations. An important limitation is that during the use of
`the licensed product, the user must always be coupled to an
`appropriate communication facility in order to send and
`receive datagrams. This creates a dependency on the com-
`munication facility. So if the communication facility is not
`available, the licensed product cannot be used. Moreover,
`some party must absorb the cost of communicating with the
`license server.

`A system for controlling the distribution of digitally
`encoded books is embodied in a system available from VPR
