Digital Creative Works such as copyrighted electronic media are packaged in a secure electronic format, or CONTAINER, and registered on associated registration server, which serves to provide on-line licensing and copyright management for that Work. Users are connected to the registration server through a computer network or the Internet to enable data transfers and to transact licenses to utilize the media. Packaged electronic media are typically created by an author or derivative user of the work. Once the packaged media is registered on the server, the media is made available for limited use and possible license through an authorization server. This limited use is specified within the minimum permissions data set assigned to each packaged media. Without a license, users are typically permitted to view the packaged media—through a system which unpackages the media—but cannot save, print or otherwise transfer the media without obtaining auxiliary permissions to do so from the authorization server. The electronic media is authenticated through digital signatures and optional encryption.
