Patent ID: 7664964

Claim:
An electronic media communication apparatus that distributes encrypted electronic media from a server to a client over a network, the server comprising: encryption means that performs encryption of electronic media distributed to the client, using an encryption system according to mechanisms in the client: electronic media specific circuit configuration means that generates logic circuit data for decrypting the encrypted electronic media and removes from the generated logic circuit data a circuit data specific to a terminal uniquely implemented for the client to generate logic circuit data specific to the electronic media; and means for transmitting to the client the encrypted electronic media and the logic circuit data generated by the electronic media specific circuit configuration means; the client comprising: means for configuring an electronic media security circuit by receiving the logic circuit data generated by the electronic media specific circuit configuration means, generating a logic circuit specific to the electronic media and combining the logic circuit and a terminal specific circuit uniquely implemented for the client; and information output means that uses the electronic media security circuit to decrypt the encrypted electronic media and converts it to usable electronic media for an output, wherein the client operates correctly only when the electronic media specific circuit and the terminal specific circuit are correctly combined.
