The invention, electronic book security and copyright protection system,
provides for secure distribution of electronic text and graphics to
subscribers and secure storage. The method may be executed at a content
provider's site, at an operations center, over a video distribution
system or over a variety of alternative distribution systems, at a home
subsystem, and at a billing and collection system. The content provider
or operations center and/or other distribution points perform the
functions of manipulation and secure storage of text data, security
encryption and coding of text, cataloging of books, message center, and
secure delivery functions. The home subsystem connects to a secure video
distribution system or variety of alternative secure distribution
systems, generates menus and stores text, and transacts through
communicating mechanisms. A portable book-shaped viewer is used for
secure viewing of the text. A billing system performs the transaction,
management, authorization, collection and payments utilizing the
telephone system or a variety of alternative communication systems using
secure techniques.
