A client terminal comprises a first application unit which transmits and receives data to and from a server, and a second application unit which transmits and receives data to and from the first application unit. An instruction transmitting unit in the second application unit transmits a user's instruction to the first application unit, and a state holding and transmitting unit transmits state information of the second application unit to the first application unit. A request generation unit in the first application unit generates a request command for the server based on the instruction received from the instruction transmitting unit, a state addition unit adds the state information received from the state holding and transmitting unit to the request command, and a request transmitting unit transmits the request command to which the state information is added to the server.

Client terminal, content utilizing system, and data transmitting/receiving method

An application on a client terminal transmits application session information indicating a state of the application itself and an application signature proving the identity of the application to a browser. The browser transmits the application session information and the application signature to a server. The server generates an HTML page in which a script specifying an operation to be performed by the application is inserted and server session information and transmits the HTML page and the server session information to the browser along with the application signature received from the browser. When the script is activated, the browser passes the information received from the server to the application. The application performs processing according to the server session information only if the application signature passed from the browser is an application signature generated by the application itself.

Client terminal, server, server-client system, cooperation processing method, program and recording medium

An information processing system includes an electronic apparatus, a server, and an external apparatus. The electronic apparatus acquires operation information for the electronic apparatus from the server, and directs the electronic apparatus to operate according to the operation information. The server receives an external apparatus identifier, electronic apparatus identifier, and operation information, from the external apparatus, and accumulates the information. The external apparatus accepts input of the electronic apparatus identifier and the operation information, and transmits the external apparatus identifier and the operation information to the server. Such an information processing system enables operation information for an electronic apparatus to be set and acquired, without directly accessing an electronic apparatus from an external apparatus, improving security.

A data transmitting and receiving method for improving transmission and reception efficiency can be obtained by improving the security through update of a control key and reduction of the frequency of the authentication and key exchange process. An STBtransmits encrypted digital data Kw (D) obtained by encrypting digital data D using a work key Kw, and an encrypted work key Kc (Kw) obtained by encrypting the Kw using a control key Kc. The Kc is periodically or non-periodically updated, and an identifier L identifying the Kc is assigned to each Kc. A VTR devicedecrypts the received Kc (Kw) using the Kc obtained by performing the authentication and key exchange process with the STB, decrypts the Kw (D) received using the Kw to obtain the D. It is determined whether or not the Kc has been updated while the reception process is suspended by referring to the transmitted L when the reception process is suspended and then resumed. If it is determined that the Kc has been updated, then the authentication and key exchange process is performed again to obtain the updated Kc.

An internet terminal, which includes a communication unit for sending and receiving packet data, an encryption unit for encrypting and decrypting packet data, a packet generation unit for generating packet data to be sent to a server apparatus, a protocol determination unit for determining a communication protocol to be used between the internet terminal and the server apparatus, a control request reading unit for reading in packet data and a control request packet that includes a control request, a control unit for receiving control information and controlling the internet terminal or a terminal apparatus accordingly. Further, the internet terminal includes a server certificate authentication unit for authenticating the validity of a server certificate sent by the server apparatus, a client certificate management unit for sending a client certificate to the server apparatus, and a storage unit for storing a terminal ID and other information.

Apparatus, method and computer software products for controlling a home terminal

A communication system includes a device and a server connected to the Internet, which transfers communications between the device and a terminal connectable to the Internet via the server. The device periodically transmits a notice packet to the server. The server transmits a connection request packet to the device in reply to the notice packet when a transfer to the device is requested from the terminal. The device transmits a TCP connection request to the server when receiving the connection request packet from the server. The server accepts the TCP connection request transmitted from the device to the server in reply to the connection request packet, to establish the TCP connection. Thus, the server transfers communications between the terminal and the device on the TCP connection after the TCP connection is established.
