Monitoring method and device

A method of implementing an interface between a first network (NW-B) and a second network (NW-A), the method being performed by a trusted entity (PFS), said method comprising:

• a step (E120) of receiving a notification message (M2) from a control device of the first network, the notification message (M2) containing a remote access rule (RAD) authorizing a user of the second network to access multimedia contents of a user of the first network;
• a step (E130) of configuring said trusted entity to use said remote access rule upon reception of an access request to the multimedia content of the first network from said user of the second network;
• a step (F160,G20) of receiving an access request (M5,M6), coming from said user (T-A) of the second network (NW-A) relating to at least one multimedia content of said user of the first network (NW-B);
• a verification step (F180) seeking to verify that said user of the second network is authorized to access multimedia contents of said user of the first network by means of the remote access rule;
• if said user of the second network is so authorized, a transfer step (F190,G40) of transferring the access request to a gateway (HGW-B) of the first network;
• and
• else a step of rejecting the request.

A treatment method implemented by a gateway (HGW-B) of a first network (NW-B), said method comprising:

• a configuration step (E170) of configuring the first network by means of a local access rule received from a control device (CCP-B) of the first network, and configuring said gateway so that, on receiving an access request from a user of the second network via a trusted entity (PFS) forming an interface between the first network and the second network, with said request relating to a catalog of multimedia contents of a user of the first network, said gateway transmits said catalog of multimedia contents which said user of the second network is authorized to access;
• on reception (F190) of a request (M5) to access said catalog of contents coming from said user of the second network, a verification step (F210) seeking to verify that said user of the second network is authorized to access said catalog;
• if said user of the second network is so authorized:
• a step (F220) of obtaining the catalog;
• and
• a step (F230) of sending said catalog to said trusted entity (PFS);
• and
• else a step of rejecting the request,
• wherein the trusted entity is configured to use a remote access rule upon reception of an access request to the multimedia content of the first network from said user of the second network.

A transfer method implemented by a control device (CCP-A) of a first network (NW-A), the method comprising:

• on reception (F150) of an access request (M5) from a user (T-A) of the first network relating to at least one multimedia content of a user of a second network (NW-B) that said user of the first network is authorized to access by an access rule, a step (F160) of interrogating a trusted entity (PFS) forming an interface between the first network and the second network in order to obtain a catalog of contents;
• and
• a step (G20) of transferring a request (M6) to access multimedia content (C) selected by the user from said catalog, the request coming from the user (T-A) of the first network and going to the trusted entity (PFS),
• wherein the trusted entity is configured to use a remote access rule upon reception of an access request to the multimedia content of the first network from said user of the second network.

A control device (CCP-B) for controlling a first network (NW-B), the device comprising:

• means for receiving a message (M1) sent by a user (T-B) of the first network, said message containing an access rule authorizing a user of a second network to access at least one multimedia content (C), said content being indexed with a content server (MS-B2) of the first network;
• means for sending to a trusted entity (PFS) constituting an interface between the first network (NW-B) and the second network (NW-A), the first notification message (M2) containing a remote access rule authorizing a user of the second network to access multimedia contents belonging to a user of the first network;
• and
• command means for commanding a gateway (HGW-B) of the first network (NW-B) by means of a local access rule configuring said gateway, such that said gateway transmits a catalog of contents to which a user of the second network is authorized to access on reception of an access request relating to said catalog coming from a user of the second network via said trusted entity (PFS),
• wherein the trusted entity is configured to use the remote access rule upon reception of an access request to the multimedia content of the first network from said user of the second network.

A trusted entity implementing an interface between a first network (NW-B) and a second network (NW-A), the entity comprising:

• means for receiving a notification message (M2) from a control device of the first network, said message containing a remote access rule authorizing a user of the second network to access multimedia contents of a user of the first network;
• means for configuring said trusted entity to use said remote access rule upon reception of an access request to the multimedia content of the first network from said user of the second network;
• means for receiving an access request (M5,M6) from a user (T-A) of the second network (NW-A) relating to at least one multimedia content of a user of the first network indexed in the first network (NW-B);
• verification means for verifying that said user of the second network is authorized to access multimedia contents of said user of the first network by means of the remote access rule;
• means for transferring the access request to a gateway (HGW-B) of the first network, which means are activated if said user of the second network is authorized;
• and
• means for rejecting the request that are activated if the user is not authorized.

A gateway (HGW-B) of a first network (NW-B), the gateway comprising:

• means for configuring the first network by means of a local access rule received from a control device (CCP-B) of the first network, adapted to configure said gateway so that, on receiving an access request from a user of the second network via a trusted entity (PFS) forming an interface between the first network and the second network, with said request relating to a catalog of multimedia contents of a user of the first network, said gateway transmits said catalog of multimedia contents that said user of the second network is authorized to access;
• verification means, activated on reception of a request (M5) to access said catalog of contents coming from a user of the second network, and serving to verify whether said user of the second network is authorized to access said catalog;
• means activated if said user of the second network is so authorized:
• to obtain the catalog;
• and
• to send the catalog to said trusted entity (PFS);
• and
• means activated to reject the request if said user is not authorized,
• wherein the trusted entity is configured to use the remote access rule upon reception of an access request to the multimedia content of the first network from said user of the second network.

A control device (CCP-A) of a first network (NW-A), the device comprising:

• means activated on reception of an access request (M5) from a user (T-A) of the first network relating to at least one multimedia content of a user of a second network (NW-B) that said user of the first network is authorized to access by an access rule (RA), to interrogate a trusted entity (PFS) forming an interface between the first network and the second network in order to obtain a catalog of contents;
• and
• means for transferring a request (M6) to access multimedia content (C) selected by the user from said catalog, the request coming from the user (T-A) of the first network and going to the trusted entity (PFS),
• wherein the trusted entity is configured to use the remote access rule upon reception of an access request to the multimedia content of the first network from said user of the second network.
