Abstract

In accordance with a particular embodiment of the present invention, a method for providing privacy protection to network users includes receiving a subscription request from a first end user. The subscription request identifies a second end user for whom the first end user would like to become a registered presence watcher. A cost to be assessed to become the registered presence watcher of the second end user is determined, and the first user is registered as the registered presence watcher of the second end user.

Claims

1. A method for providing privacy protection to network users, comprising:

receiving a subscription request from a first end user, the subscription request identifying a second end user for whom the first end user would like to become a registered presence watcher;

determining a cost to be assessed to become the registered presence watcher of the second end user; and

registering the first user as the registered presence watcher of the second end user.

2. The method of claim 1, further comprising:

receiving a first communication from a first endpoint associated with the first end user, the first communication directed to a second endpoint associated with the second end user;

determining that the first end user is the subscribed presence watcher of the second end user; and

forwarding the communication to the second endpoint.

3. The method of claim 1, wherein the cost comprises a subscription fee to be paid by the first end user.

4. The method of claim 1, wherein the cost comprises a computational cost to be incurred by the first end user.

5. The method of claim 4, further comprising:

receiving a solution to a puzzle; and

authorizing a communication session between the first end user and the second end user in response to receiving the solution to the puzzle.

6. The method of claim 4, wherein the computation cost comprises the execution of programmed commands to enable the monitoring of presence information.

7. The method of claim 1, further comprising

maintaining an association list identifying a plurality of end users with whom the first end user is associated in a memory;

and

storing information from the subscription request in the memory.

8. The method of claim 7, wherein storing the information from the subscription request in the memory comprises updating the association list to include the second end user.

9. The method of claim 1, further comprising providing presence information to the first end user, the presence information indicating the availability of the second end user at least the second endpoint.

10. The method of claim 9, wherein providing the presence information to the first end user comprises:

determining the availability of the second end user to the establishment of a communication session between the first endpoint and the second endpoint; and

displaying the availability of the second end user to the first end user at the first endpoint.

11. A system for providing privacy protection to network users, comprising:

a plurality of endpoints operable to establish one or more communication sessions over a network; and

a presence server coupled to the network, the presence server operable to;

receive a subscription request from a first end user, the subscription request identifying a second end user for whom the first end user would like to become a registered presence watcher;

determine a cost to be assessed to become the registered presence watcher of the second end user; and

register the first user as the registered presence watcher of the second end user.

12. The system of claim 11, wherein the presence server is further operable to:

receive a first communication from a first endpoint associated with the first end user, the first communication directed to a second endpoint associated with the second end user;

determine that the first end user is the subscribed presence watcher of the second end user; and

forward the communication to the second endpoint.

13. The system of claim 11, wherein the cost comprises a subscription fee to be paid by the first end user.

14. The system of claim 11, wherein the cost comprises a computational cost to be incurred by the first end user.

15. The system of claim 14, wherein the computational cost comprises the generation of a solution to a puzzle, the presence server further operable to authorize a communication session between the first end user and the second end user in response to receiving the solution to the puzzle.

16. The system of claim 14, wherein the computation cost comprises processing required to enable the monitoring of presence information.

17. The system of claim 11, wherein the presence server is further operable to:

maintain an association list identifying a plurality of end users with whom the first end user is associated in a memory; and

store information from the subscription request in the memory.

18. The system of claim 17, wherein the presence server is further operable to update the association list to include the second end user.

19. The system of claim 11, wherein the presence server is further operable to provide presence information to the first end user, the presence information indicating the availability of the second end user at least the second endpoint.

20. The system of claim 19, wherein the presence server is further operable to:

determine the availability of the second end user to the establishment of a communication session between the first endpoint and the second endpoint; and

display the availability of the second end user to the first end user at the first endpoint.

21. A system for providing privacy protection to network users, comprising:

means for receiving a subscription request from a first end user, the subscription request identifying a second end user for whom the first end user would like to become a registered presence watcher;

means for determining a cost to be assessed to become the registered presence watcher of the second end user; and

means for registering the first user as the registered presence watcher of the second end user.

22. Logic embodied in a computer readable medium, the computer readable medium comprising code operable to:

receive a subscription request from a first end user, the subscription request identifying a second end user for whom the first end user would like to become a registered presence watcher;

determine a cost to be assessed to become the registered presence watcher of the second end user; and

register the first user as the registered presence watcher of the second end user.
