Abstract

Users on a peer-to-peer network, particularly a local subnet or ad hoc wireless network, may publish first contact information to a graph or data store on the network. The first contact information may include a certificate with a public-key and a user identification, such as a peer name. Other users may discover the first contact information and use the first contact information to request additional information from the user. Data in the first contact information may also be “promoted” by adding the information to a trusted contacts database, allowing the user additional privileges. The user publishing the first contact information may be given the opportunity to approve or deny the request for additional information.

Claims

1. A method of acquiring contact information related to users on a peer-to-peer network comprising:

determining the presence of a user on a peer-to-peer network;

sending a request message to the user, the request message comprising a request for contact information;

receiving contact information from the user, the contact information comprising information corresponding to the user; and

adding the contact information to a local contact database.

2. The method of claim 1, wherein determining the presence of the user further comprises at least one of querying a user graph of a peer-to-peer network or use of a discovery protocol.

3. The method of claim 2, further comprising displaying information associated with the user in a pane of a display window.

4. The method of claim 3, wherein the displaying information associated with the user further comprises displaying public data about the user.

5. The method of claim 3, wherein information associated with the user further comprises displaying status information about the user.

6. The method of claim 1, wherein the local contact database comprises at least one of an address book, a messaging application, or a meeting application.

7. The method of claim 1, wherein determining the presence of a user from the user comprises receiving a public key corresponding to the user.

8. The method of claim 7, further comprising adding the public key to a database comprising trusted contacts.

9. The method of claim 8, wherein adding the public key to the database comprising trusted contacts grants additional access privileges to the user.

10. A method for distributing contact information for users on a peer-to-peer network comprising:

storing first and second contact information corresponding to a user;

publishing the first contact information;

receiving a request from a requesting party over a peer-to-peer network for the second contact information;

displaying a query to the user requesting authorization to share the contact information with the requesting party;

receiving a response to the query; and

sending the second contact information to the requesting party when the response to the query is affirmative.

11. The method of claim 10, further comprising:

generating a certificate comprising a public key and user identification information; and

providing the certificate when publishing the first contact information.

12. The method of claim 11, wherein generating the certificate further comprises generating a self-signed certificate comprising a public key and user identification information.

13. The method of claim 10, further comprising verifying an identity of the user at a remote peer using the certificate.

14. A computer adapted for a operation in a peer-to-peer network, the computer comprising:

a processing unit for executing instructions;

a networking device coupled to processing unit for coupling data transmitted between the computer and the peer-to-peer network;

a memory for storing computer executable instructions, coupled to the processing unit, the computer executable instructions for executing a method comprising;

obtaining an identity record for a user publishing contact information on a subnet of the peer-to-peer network;

displaying information from the identity record;

sending a request message to the user, the request message comprising a request for additional contact information;

receiving a response to the request message;

adding the additional contact information to a local contact database if the response includes the additional contact information.

15. The computer of claim 14, further comprising extracting addressing data from the identity record, wherein the addressing data is used for sending the request message to the user.

16. The computer of claim 14, wherein the identity record comprises at least one of a certificate or information corresponding to presence on the subnet.

17. The computer of claim 14, wherein obtaining the identity record for a user further comprises at least one of a query of a meeting graph or use of a discovery protocol.

18. The computer of claim 14, wherein displaying information from the identity record further comprises displaying in a pane of a display window at least one of public data about the user, contact information for the user, and status information about the user.

19. The computer of claim 14, further comprising putting data from a public-key infrastructure certificate into a trusted contacts database.

20. The computer of claim 19, further comprising verifying user identity using the public key infrastructure certificate and granting the user privileges corresponding to the user identity.
