Abstract

Embodiments of the present invention address deficiencies of the art in respect to validating a specified identity for a participant to a chat session and provide a novel and non-obvious method, system and computer program product for trusted contact name validation for an instant messaging session. In one embodiment of the invention, an instant messaging contact name validation method can be provided. The method can include establishing a trusted relationship among at least two instant messaging servers in a trusted community of instant messaging servers, receiving a request to add a specified contact to a list of instant messaging contacts in association within one of the instant messaging servers in the trusted community of instant messaging servers, and validating the specified contact with another of the instant messaging servers in the trusted community of instant messaging servers.

First claim

We claim:

1. An instant messaging contact name validation method comprising:
establishing a trusted relationship among at least two instant messaging servers in a trusted community of instant messaging servers by establishing between the at least two instant messaging servers an authenticated communicative coupling over which session initiation protocol (SIP) messages are exchanged;
receiving a request to add a specified contact to a list of instant messaging contacts in association within one of the at least two instant messaging servers in the trusted community of instant messaging servers; and,
validating the specified contact with another of the at least two instant messaging servers in the trusted community of instant messaging servers only on behalf of ones of the instant messaging servers in the trusted community among which a trusted relationship has been established by way of the authenticated communicative coupling over which SIP messages are exchanged, the validating comprising passing the specified contact to the another of the at least two instant messaging servers, comparing the specified contact with a list of valid contacts managed in the another of the least two instant messaging servers, and matching the specified contact with the list of valid contacts managed in the another of the least two instant messaging servers.

2. The instant messaging contact name validation method of claim 1 , wherein the instant messaging servers are chat servers.

3. The instant messaging contact name validation method of claim 1 , wherein receiving the request to add the specified contact to the list of instant messaging contacts in association within the one of the at least two instant messaging servers in the trusted community of instant messaging servers, comprises receiving a request to add a specified contact name to the list of instant messaging contacts in association within the one of the at least two instant messaging servers in the trusted community of instant messaging servers.

4. The instant messaging contact name validation method of claim 3 , wherein validating the specified contact with the another of the at least two instant messaging servers in the trusted community of instant messaging servers, further comprises validating the specified contact name with the another of the at least two instant messaging servers in the trusted community of instant messaging servers.

5. The instant messaging contact name validation method of claim 1 , wherein validating the specified contact with the another of the at least two instant messaging servers in the trusted community of instant messaging servers, further comprises reporting the specified contact as invalid.

6. The instant messaging contact name validation method of claim 1 , wherein validating the specified contact with the another of the at least two instant messaging servers in the trusted community of instant messaging servers, further comprises reporting the specified contact as invalid when the specified contact cannot be located among a list of valid contact names for the another of the at least two instant messaging servers.

7. The instant messaging contact name validation method of claim 1 , wherein validating the specified contact with the another of the at least two instant messaging servers in the trusted community of instant messaging servers, further comprises reporting the specified contact as invalid and returning a listing of possible correct contacts to the one of the at least two instant messaging servers in the trusted community of instant messaging servers.

8. The instant messaging contact name validation method of claim 7 , further comprising:
determining that the specific contact is invalid;
searching the list of valid contacts managed in the another of the at least two instant messaging servers using the specified contact found to be invalid according to fuzzy matching to locate possible correct contacts; and,
creating the listing of possible correct contacts.

9. An instant messaging data processing system comprising:
a plurality of instant messaging servers in a trusted community of instant messaging servers, the instant messaging servers in the trusted community comprising an established trusted relationship with each other using an authenticated communicative coupling over which session initiation protocol (SIP) messages are exchanged; and,
trusted contact name validation logic coupled to each of the instant messaging servers, the trusted contact name validation logic comprising program code enabled to receive a request to add a specified contact to a list of instant messaging contacts in association within one of the instant messaging servers in the trusted community of instant messaging servers, and to validate the specified contact with another of the instant messaging servers in the trusted community of instant messaging servers only on behalf of ones of the instant messaging servers in the trusted community among which a trusted relationship has been established by way of the authenticated communicative coupling over which SIP messages are exchanged, the validating comprising passing the specified contact to the another of the instant messaging servers, comparing the specified contact with a list of valid contacts managed in the another of the instant messaging servers, and matching the specified contact with the list of valid contacts managed in the another of the instant messaging servers.

10. The instant messaging data processing system of claim 9 , wherein the trusted contact name validation logic further comprises program code enabled to:
determine that the specific contact is invalid;
search the list of valid contacts managed in the another of the instant messaging servers using the specified contact found to be invalid according to fuzzy matching to locate possible correct contacts; and,
create a listing of possible correct contacts.

11. A computer program product comprising a non-transitory computer usable storage medium storing thereon computer usable program code for instant messaging contact name validation, the computer usable program code comprising a set of instructions which when executed by a machine cause the machine to perform:
establishing a trusted relationship among at least two instant messaging servers in a trusted community of instant messaging servers by establishing between the at least two instant messaging servers an authenticated communicative coupling over which session initiation protocol (SIP) messages are exchanged;
receiving a request to add a specified contact to a list of instant messaging contacts in association within one of the at least two instant messaging servers in the trusted community of instant messaging servers; and,
validating the specified contact with another of the at least two instant messaging servers in the trusted community of instant messaging servers only on behalf of ones of the instant messaging servers in the trusted community among which a trusted relationship has been established by way of the authenticated communicative coupling over which SIP messages are exchanged, the validating comprising passing the specified contact to the another of the at least two instant messaging servers, comparing the specified contact with a list of valid contacts managed in the another of the least two instant messaging servers, and matching the specified contact with the list of valid contacts managed in the another of the least two instant messaging servers.

12. The computer program product of claim 11 , wherein the instant messaging servers are chat servers.

13. The computer program product of claim 11 , wherein the receiving
