Authentication Proxy Method, Distribution Management Device, And Authentication Proxy Method Program
[Problem] To obtain an authentication proxy method, a distribution management device to be proxy for authentication, etc. in which a user does not have to be aware of authentication in distribution of contents needing authentication. [Means for Resolution] A distribution management device 22 for managing distribution of signals including data of contents to a mobile communication network 10 determines whether a contents providing server 31 on another communication network 30 has made a transmission request for a signal including authentication data in response to a distribution request for a signal including data of contents which request has been sent from a mobile terminal device 11 through the mobile communication network 10 . When it is concluded that the transmission request has been made, the distribution management device 22 creates a signal including the authentication data for the mobile terminal device 11 and transmits the created signal to the contents providing server 31.

determining whether a transmission request for a signal including authentication data has been made from a contents providing server to a terminal device or not; and
creating a signal including the authentication data for the terminal device and transmitting the created signal to the contents providing server when it is concluded that the transmission request has been made.
2 . An authentication proxy method characterized in that a distribution management device for managing distribution of signals including data of contents to one communication network performs:
determining whether a transmission request for a signal including authentication data has been made from a contents providing server on another communication network in response to a distribution request for a signal including data of contents from a terminal device through the one communication network or not; and
creating a signal including the authentication data for the terminal device and transmitting the created signal to the contents providing server when it is concluded that the transmission request has been made.
3 . An authentication proxy method according to claim 2 , characterized by including the steps of:
searching authentication data stored in a storage means in advance, so as to acquire authentication data corresponding to the terminal device, the contents or the contents providing server; and
creating a signal including the acquired authentication data.
4 . A distribution management device characterized in that:
the distribution management device is provided between one communication network and another communication network; and
when a transmission request for a signal including authentication data for a terminal device on the one communication network has been made from a contents providing server on the other communication network, the distribution management device creates a signal including the authentication data for the terminal device and transmits the created signal to the contents providing server.
5 . A distribution management device characterized in that:
the distribution management device is provided between one communication network and another communication network; and
the distribution management device comprises:
a storage means for storing authentication data about one or plural terminal devices;
a data processing means for searching the storage means so as to acquire authentication data corresponding to one of the terminal devices, and creating a signal including the acquired authentication data, when the terminal device makes a distribution request for a signal including data of contents and a contents server makes a transmission request for a signal including the authentication data for the terminal device in response to the distribution request; and
a communication means for transmitting the signal including the authentication data to the contents providing server.
6 . A distribution management device according to claim 5 , characterized in that:
the storage means stores one or plural pieces of the authentication data for each of the terminal devices correspondingly to the contents or the contents providing server; and
the data processing means searches authentication data corresponding to the terminal device, the contents or the contents providing server.
7 . A distribution management device according to claim 4 , characterized in that the data of the contents are data in a streaming format, and the signal including the authentication data is a signal created according to RTSP.
8 . A distribution management device according to claim 4 , characterized in that the one communication network is a mobile communication network for wireless communication with mobile terminal devices.
9 . An authentication proxy method program characterized by making a computer execute the steps of:
determining whether a signal indicating a request for authentication data for a terminal device has been transmitted from a contents providing server or not in response to a distribution request from the terminal device for a signal including data of contents; and
creating a signal including the authentication data for the terminal device and transmitting the created signal to the contents providing server through a communication means when it is concluded that the signal indicating the request for the authentication data has been transmitted.
10 . An authentication proxy method program according to claim 9 , characterized by making the computer execute the steps of:
searching authentication data stored in a storage means in advance, so as to acquire authentication data corresponding to the terminal device, the contents or the contents providing server; and
creating a signal including the acquired authentication data.
11 . A distribution management device according to claim 5 , characterized in that the data of the contents are data in a streaming format, and the signal including the authentication data is a signal created according to RTSP.
12 . A distribution management device according to claim 6 , characterized in that the data of the contents are data in a streaming format, and the signal including the authentication data is a signal created according to RTSP.
13 . A distribution management device according to claim 5 , characterized in that the one communication network is a mobile communication network for wireless communication with mobile terminal devices.
