More Information
Summary:An electronic publishing and distribution system is provided for dissemination of written materials that can be read on a portable electronic book. A host computer (16) contains an inventory that can be selected and then downloaded into the book's memory. The host computer keeps track of the transactions, and encodes the data prior to downloading, using an encryption system (34). The encrypted data cannot be decrypted until it is resident in the memory of the book. Upon receipt of the encrypted data, the book decrypts the data. A plurality of electronic keys is provided corresponding (36, 37) to graphical representations such as icons adjacent to each key.
