Abstract
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.
