Abstract

In accordance with various aspects, the present invention relates to accessing and publishing documents between two computer systems or nodes that are connected together in a network environment. The system and method for name resolution stores an identity information document containing a user-friendly handle signifying identity, such as an email address, and a machine location, such as an IP address, for the publishing computer system where the documents are stored. Next, the system and method intercepts an initial request for access to documents when the initial request includes a user-friendly handle and replaces the user-friendly handle with the machine location, so that network users may easily access these documents through knowledge only of the user-friendly handle.

Claims

6. The method of claim 1 further comprising an initial step of receiving at the second computer system the identity information document from the first computer system.

7. A method of publishing documents between a plurality of nodes, the nodes connected in a network environment, said method comprising:

sending an identity information document from a publishing node to an accessing node, the identity information document comprising a user-friendly handle identifying a principal of the publishing node and a machine location for the publishing node;

storing the identity information document on the accessing node;

resolving at the accessing node the user-friendly handle with the machine location in a request for access to documents, wherein the request is made to the publishing node from a user of the accessing node via a user interface implemented on the accessing node; and

sending the request for access to documents from the accessing node to the publishing node.

8. The method of claim 7 wherein the user-friendly handle comprises an email address.

9. The method of claim 7 wherein the user-friendly handle comprises a telephone number.

10. The method of claim 7 wherein the machine location comprises an IP address.

11. The method of claim 7 wherein the machine location comprises a public key.

12. The method of claim 11 further comprising:

using the public key to determine the current machine location for the publishing node.

13. The method of claim 11 further comprising:

registering an encrypted machine name and a registered machine location for the publishing node with a DNS server;

resolving the user-friendly handle with the public key;

converting the public key to the encrypted machine name;

using the encrypted machine name to look up the registered machine location for the publishing node on the DNS server; and

sending the request for access to documents to the registered machine location.

14. The method of claim 7 further comprising:

verifying that the accessing node has authorization from the publishing node to review the requested documents before publishing the requested documents.

15. The method of claim 7 further comprising:

delivering a path name for documents stored on the publishing node to the accessing node.

16. The method of claim 15 wherein the path name is delivered to the accessing node by email.

17. The method of claim 7 further comprising:

delivering a path name for documents stored on the publishing node to a principal of the accessing node.

18. The method of claim 17 wherein the path name is delivered to the principal of the accessing node by a telephone call.

19. The method of claim 7 wherein the resolving step further comprises:

intercepting the request for access to documents when the request is directed to the user-friendly handle;

finding a matching identity information document having a user-friendly handle that matches the user-friendly handle in the request;

determining the machine location from the matching identity information document; and

amending the request to substitute the user-friendly handle with the machine location.

22. The method of claim 7 wherein the identity information document further comprises more than one machine location for principal identified by the user-friendly handle.

20. The method of 7 further comprising:

delivering a path name combined with the user-friendly handle to the accessing node; and

parsing the path name from the user-friendly handle prior to resolving the user-friendly handle with the machine location.

21. The method of claim 20 further comprising:

adding the path name to the request for access to documents before sending the request to the publishing node.

23. A method of using a user-friendly handle to access documents stored on a first computer system in a network environment, the method comprising:

storing at a second computer system an identity information document from the first computer system, the identity information document comprising a user-friendly handle identifying a first user of the first computer system and a machine location of the first computer system;

implementing a user interface on the second computer system to enable a second user of the second computer system to request access to documents stored on the first computer system;

receiving at the user interface implemented on the second computer system a request from the second user of the second computer system to access a first document of the documents stored on the first computer system, the request including the user-friendly handle and being directed to the first computer system;

intercepting at the second computer system the request from the user interface to access the first document;

amending at the second computer system the request to replace the user-friendly handle with the machine location of the first computer system;

sending the amended request from the second computer system to the machine location of the first computer system; and

accessing the first document at the second computer system.

24. The method of claim 23 wherein the user-friendly handle is an email address.

25. The method of claim 23 wherein the machine location comprises an IP address.
