Abstract

A system and method for receiving first information from a primary individual and establishing the primary individual as a first trusted user using the first information. Second information is then received from an interested subscriber, the second information including information relating the interested subscriber to the primary individual and establishing the interested subscriber as a second trusted user using the second information. A triggering event is received from the primary individual, where the triggering event includes third information verifying the primary individual as the first trusted user. An indication is provided to the interested subscriber based on the triggering event.

Claims

1. A non-transitory computer readable storage medium storing a set of instructions executable by a processor, the set of instructions, when executed by the processor, causing the processor to perform operations comprising:

receiving, at a rendezvous point, a registration message including first information from a primary individual, the rendezvous point being a location remote from the primary individual receiving subscriptions requests for a multicast group and distributing messages to the multicast group;

establishing the primary individual as a first trusted user using the first information;

receiving, at the rendezvous point via a subscription router, a subscribing message including second information from an interested subscriber to the primary individual;

establishing the interested subscriber as a second trusted user authorized to receive private information relating to the first trusted user using the second information;

receiving, via a source router, a triggering event including a plurality of data packets from the primary individual, the plurality of data packets including the private information relating to the first trusted user, where the triggering event includes third information verifying the primary individual as the first trusted user;

multicasting the data packets from the rendezvous point to the interested subscriber based on the triggering event; and

wherein the first information, The second information, and the triggering event are received by an encrypted secure database.

2. The non-transitory computer readable storage medium of claim 1, wherein the operations further comprise:

forwarding the subscribing message from the rendezvous point to the source.

3. The non-transitory computer readable storage medium of claim 1, wherein the operations further comprise:

updating the first information from the primary individual;

providing an indication based on the triggering event to the interested subscriber further based on the updated first information.

4. The non-transitory computer readable storage medium of claim 1, wherein the interested subscriber is a one or more interested subscribers.

5. The non-transitory computer readable storage medium of claim 1, wherein the indication includes a time-stamp.

6. The non-transitory computer readable storage medium of claim 2, wherein the rendezvous mechanism includes a multicast routing protocol.

7. The non-transitory computer readable storage medium of claim 6, wherein the multicast routing protocol is one of a Protocol-Independent Multicast Sparse Mode architecture and a Core-Based Trees architecture.

8. A system, comprising:

a hardware computer processor;

a first receiving element for receiving, at a rendezvous point, a registration message sent from a source router and including first information from a primary individual, the rendezvous point being a location remote from the primary individual receiving subscription requests for a multicast group and distributing messages to the multicast group;

a first verification element for establishing the primary individual as a first trusted user using the first information;

a second receiving element for receiving, at the rendezvous point, a subscribing message sent from a subscription router and including second information from an interested subscriber, the second information including information relating the interested subscriber to the primary individual;

a second verification element for establishing the interested subscriber as a second trusted user authorized to receive private information relating to the first trusted user using the second information;

a third receiving element for receiving, at the rendezvous point, a triggering event from the primary individual, where the triggering event includes a plurality of data packets the plurality of data packets including the private information relating to the first trusted user, and third information verifying the primary individual as the first trusted user;

an indication element for providing, from the rendezvous point, an indication to the interested subscriber based on the triggering event, the indication including the plurality of data packets; and

wherein the first information, the second information, and the triggering event are received by an encrypted secure database.

9. The system of claim 8, wherein the subscription message is forwarded from the rendezvous point to the source.

10. The system of claim 8, further comprising:

an updated subscription information based on a further information from the primary individual, wherein the indication based on the triggering event is provided to the interested subscriber further based on the updated first information.

11. The system of claim 8, wherein the interested subscriber is one or more interested subscribers.

12. The system of claim 8, wherein the indication includes a time-stamp.

13. The system of claim 9, wherein the rendezvous mechanism includes a multicast routing protocol.

14. The system of claim 13, wherein the multicast routing protocol is one of a Protocol-Independent Multicast Sparse Mode architecture and a Core-Based Trees architecture.
