摘要:
The present invention relates to an information-processing system, an information-processing apparatus and an information-processing method. At a step S1, a PDA transmits a request for purchase of a content to a server. At steps S11, S12 and S14, the server receives the request for purchase of a content from the PDA and transmits the content to the PDA. At a step S5, the PDA transmits a request for preservation of the content to the server. At a step S16, the server generates a preservation ID based on a user ID for identifying the user of the PDA and based on a content ID for identifying the content, and issues the preservation ID to the PDA. At the next step S17, the server stores the issued preservation ID in a preservation-ID database by associating the preservation ID with the content ID. At a step S6, the PDA receives the issued preservation ID from the server and stores the preservation ID in a memory. The present invention can also be applied to an information management system.

The present invention relates to an information processing apparatus by which a communication channel providing a high degree of privacy is established between a PDA and a data communication server. Data encrypted with a temporary key is shared by a PDA and a memory card. The memory card decrypts the data by the shared temporary key, and then stores the data in the memory card. Data encrypted with a temporary key shared by a PC and the memory card. The PC decrypts the data by the shared temporary key, and then stores the data in the PC. The PC and the data communication server are connected to each other, and perform mutual authentication. The data encrypted with a temporary key shared by the PC and the data communication server as a result of the authentication is transmitted from the PC to the data communication server via a broadband network.
摘要:
Contents and its key are supplied in different procedures. License management program authenticates telephone-integrated terminal device and authenticates first server or second server. Server LCM controls the reception of contents and key transmission requests and of data for identifying first server or second server. If data for identifying first server are received, contents and its key are received from first server in a procedure corresponding to first server. If data for identifying said server are received, contents and its key are received from second server in a procedure corresponding to second server. Server LCM controls the transmission of contents and its key to telephone-integrated terminal device.

The present invention is intended to quickly download contents while preventing unauthorized contents usage. PD authentication program authenticates telephone-integrated terminal device. Server authentication program authenticate key server. Server LCM controls the reception of a request for data for identifying key server and a key from telephone-integrated terminal device. On the basis of the data for identifying key server, server LCM sends a request for the key to key server and receives the requested key from key server. Key distribution program sends the key to telephone-integrated terminal device.
