Electronic speaking document viewer, authoring system for creating and editing electronic contents to be reproduced by the electronic speaking document viewer, semiconductor storage card and information provider server

A semiconductor storage card comprising:

• a non-volatile memory for storing unencrypted text data based on which typographic images are displayed by means of a typographic images displaying unit of an electronic viewer and for storing encrypted intermediate language data indicative of rules for how to phonetically read the text content data, wherein a speech synthesis is performed by means of a speech synthesis unit of the electronic viewer with reference to said unencrypted text data and said encrypted intermediate language data, wherein said non-volatile memory further comprises:
• a first storage region for storing said text data;
• a second storage region for storing said intermediate language data;
• and
• a third read only storage region for storing an ID number for identifying the semiconductor storage card itself, wherein said intermediate language data is encrypted by the use of the ID number;
• and
• a thin case for supporting said non-volatile memory.

An information provider server comprising:

• an information database for storing text data consisting of letters and intermediate language data indicative of rules for how to phonetically read said text data in the form of unencrypted plain data;
• and
• an information provider server connected to said information database,
• wherein said information provider server comprises an encryption program, receives a request for said text data and said intermediate language data together with data for use in encryption through a network, encrypts said intermediate language data by the use of said data for use in encryption and sends a response accompanied by said intermediate language data as encrypted together with said text data through said network,
• wherein said data for use in encryption is an ID number of a semiconductor storage card in the form of a detachable card type storage medium in which said text data consisting of letters and said intermediate language data indicative of the rules of how to phonetically read said text data, and said data for use in encryption is used to generate an encryption key.
