Abstract: According to one embodiment, an apparatus includes a permission/inhibition information storage which stores a permission/inhibition information file, a changer which changes a first encryption key of a first private key encrypted with the first public key to the second public key by using the first re-encryption key, a first storage which stores a second private key in a device private key temporary storage, a second storage which stores a second re-encryption key in a re-encryption key storage, a permission/inhibition information registration module which registers second permission/inhibition information in the permission/inhibition information file, and a transmitter which transmits the second private key in the re-encryption key storage to the second terminal.

Abstract: An imaging distribution apparatus includes a reception unit configured to receive a distribution request for distribution of a specific program from a client apparatus via a network, a program scenario acquisition unit configured to acquire a program scenario corresponding to the specific program requested for by the distribution request, a content acquisition unit configured to acquire a plurality of information contents based on the program scenario, a conversion unit configured to convert the information contents to image scene based on the program scenario, an encoding unit configured to encode the image scene, to generate a stream, and a stream distribution unit configured to distribute the stream to the client apparatus via the network.

Abstract: According to one embodiment, an information processing apparatus provides a data storage service via a network for storing data of a user. The apparatus includes a recipient setting module and an account issuing module. The recipient setting module is configured to accept and set a recipient of data and recipient-receivable data, designated by the user. The account issuing module is configured to issue an account to the recipient set by the recipient setting module. The account has an access right for enabling the recipient to access the recipient-receivable data.

Abstract: An information supplying server includes a retrieval request receiver (101) for receiving a query containing a keyword, a retriever (102) for transmitting a received query to a retrieval server identified by a retrieval destination identifier associated with a superordinate concept of received keyword in retrieval destination data, and receiving a retrieved data from the retrieval server, a narrowing word determiner (103) for determining a narrowing word in accordance with a priority determined from a provisional priority set to a narrowing word candidate as a candidate of narrowing word for use to narrow down information from retrieved data, and a degree of relevancy set to a superordinate concept of narrowing word candidate and a superordinate concept of the keyword, and a supply data transmitter (107) configured to transmit to the client terminal a supply data as a synthesis of the retrieved data with a new query having a determined narrowing word combined with the received query.
