Abstract

In a configuration allowing a client to be designated as a proxy server, the proxy server to register an external client to serve as a member client and the member to utilize a content, a content-utilization management server designates a client as a proxy server whereas the proxy server checks an external client connected to an external network and registers the external client to serve as a member client having a right to utilize a content managed by the content-utilization management server. Then, the proxy server gives a license to the external client as a right to utilize such a content. Thus, the external client not connected to a local network of the content-utilization management server is also capable of utilizing the content based on the license.

Claims

1. An information-processing method comprising:

a proxy-server designation step of designating a client as a proxy server by execution of a communication through a local network between a content-utilization management server connected to said local network and said client; and

a member registration step of setting and registering an external client to serve as a member client having a right to utilize a content managed by said content-utilization management server on the basis of a result of processing carried out by said proxy server to verify said external client.

2. An information-processing method according to claim 1, wherein a communication carried out at said member registration step as a communication between said proxy server and said external client is processing carried out outside said local network to which said content-utilization management server is connected.

3. An information-processing method according to claim 1, further comprising a member registration completion notification step of driving said proxy server to inform said content-utilization management server that an operation to register said external client to serve as a member client has been completed.

4. An information-processing method according to claim 1, wherein, at said proxy-server designation step, as verification processing of a client to be designated as a proxy server, said content-utilization management server carries out a membership confirmation process to confirm membership of said client to be designated as a proxy server by verifying that said client is a member client already registered in said content-utilization management server and a locality confirmation process to confirm locality of said client to be designated as a proxy server by verifying that said client is a client connected to said local network, to which said content-utilization management server is connected, and designates said client as a proxy server on condition that said membership and said locality are confirmed.

5. An information-processing method according to claim 1, wherein, at said member registration step, as verification processing of said external client, said proxy server carries out a locality confirmation process to confirm locality of said external client by verifying that said external client is a client connected to an external local network to which said proxy server is connected and a member registration process to register said external client to serve as a member client on condition that said locality is confirmed.

6. An information-processing method comprising:

a license-granting right delegation step of permitting a proxy server to grant a license to an external client by carrying out a communication between a content-utilization management server and said proxy server, which are connected to a local network, through said local network; and

a license-granting step of granting a license from said proxy server to said external client as a right to utilize a content managed by said content-utilization management server on the basis of a result of a process carried out by said proxy server to verify said external client.

7. An information-processing method according to claim 6, wherein, a communication carried out at said license-granting step as a communication between said proxy server and said external client is processing carried out outside said local network to which said content-utilization management server is connected.

8. An information-processing method according to claim 6, further comprising a license-granting completion notification step of driving said proxy server to inform said content-utilization management server that an operation to grant a license to said external client has been completed.

9. An information-processing method according to claim 6, wherein, at said license-granting right delegation step, as verification processing of a proxy server, said content-utilization management server carries out a membership confirmation process to confirm membership of said proxy server by verifying that said proxy server is a member client already registered in said content-utilization management server and a locality confirmation process to confirm locality of said proxy server by verifying that said proxy server is a client connected to said local network, to which said content-utilization management server is connected, and delegates a right to grant a license to said proxy server on condition that said membership and said locality are confirmed.

10. An information-processing method according to claim 6, wherein, at said license-granting step, as verification processing of said external client, said proxy server carries out a locality confirmation process to confirm locality of said external client by verifying that said external client is a client connected to an external local network to which said proxy server is connected and a license-granting process to grant a license from said proxy server to said external client on condition that said locality is confirmed.

11. An information-processing apparatus used as a content-utilization management server, comprising:

a storage unit for storing a member-client list of registered clients each having a right to utilize a content; and

a data-processing unit for carrying out a process to verify a proxy server,

wherein;

said data-processing unit includes;

a member-client list management unit for carrying out a membership confirmation process to confirm membership of said proxy server on the basis of said member-client list; and

a locality check unit for carrying out a locality confirmation process to confirm locality of said proxy server by verifying that said proxy server is a client connected to a local network, to which said content-utilization management server is connected, and

designation of a client as a proxy server or delegation of a right to grant a license to said proxy server is performed on condition that said membership and said locality are confirmed.

12. A computer program to be executed to carry out a proxy-server designation process of designating a client as a proxy server by execution of a communication through a local network between a content-utilization management server connected to said local network and said client, said computer program comprising:

a membership confirmation step of confirming membership of said client to be designated as a proxy server by verifying that said client is a member client already registered in said content-utilization management server;

a locality confirmation step of confirming locality of said client to be designated as a proxy server by verifying that said client is a client connected to said local network, to which said content-utilization management server is connected; and

a step of designating said client as a proxy server on condition that said membership and said locality are confirmed.

13. A computer program to be executed to carry out a license-granting right delegation process of permitting a proxy server to grant a license to an external client by carrying out a communication between a content-utilization management server and said proxy server, which are connected to a local network, through said local network, said computer program comprising:

a membership confirmation step of confirming membership of said proxy server by verifying that said proxy server is a member client already registered in said content-utilization management server;

a locality confirmation step of confirming locality of said proxy server by verifying that said proxy server is a client connected to said local network, to which said content-utilization management server is connected; and

a step of delegating a right to grant a license to said proxy server on condition that said membership and said locality are confirmed.
