ABSTRACT:
A digital rights management system for the distribution, protection and use of electronic content. The system includes a client architecture which receives content, where the content is preferably protected by encryption and may include a license and individualization features. Content is protected at several levels, including: no protection; source-sealed; individually-sealed (or “inscribed”); source-signed; and fully-individualized (or “owner exclusive”). The client components include a script of instructions that provides individualization information to a distributor of content so that the content may be individualized for the client and/or its operating persona.
