Abstract

Disclosed is a method and system for managing contacts for a communication system by storing contact information in a centralized storage system and permitting receiving users to access the centralized contact information storage system using a token passed with communications from a sending user. The communications system may be a trusted network with trusted sending and receiving members. Each communications system member provides contact information the member may wish to make available to other parties. The member may also create a policy defining which contact information may be made available to different classes of users. A member of the communications system generates a message to send to a receiving user. A token that identifies the sending user to the communications system is embedded into the message to be sent to the receiving user. The receiving user, after identifying the message as a message containing a token, may request contact information for the sending user from the communications system using the token identifying the sending user to the communication system. The communication system delivers a subset of the sending user'"'"'s contact information to the receiving user based on the sending user'"'"'s contact information and policy definitions stored in the centralized contact information storage system of the communication systems. The system and method are especially adaptable to e-mail communications, but other forms of electronic communications may also be included in an embodiment, either solely or in combination.

Claims

1. A method, comprising:

receiving, at a communication system, sender contact information and security policy information from a sending user, said security policy information defining a user relationship and a subset of said sender contact information;

sending an electronic message including a sender identification token from the communication system to a receiving user, wherein the sender identification token identifies said sending user;

in response to a reception of the electronic message, at the communication system, from said sending user, extracting, by the communication system, from the electronic message, the sender identification token;

receiving, at the communication system, a request from the receiving user for the sender contact information, the request including the sender identification token;

obtaining, in response to the request, the subset of the sender contact information from a contact database, based on the sender identification token;

in response to the request, determining said user relationship between the receiving user and the sending user; and

sending, from the communication system, the subset of the sender contact information, based on the security policy information and the user relationship, wherein

the subset of the sender contact information is a first subset including an e-mail address of the sending user, based on said user relationship indicating said receiving user accesses said communication system via a publicly accessible gateway,

the subset of the sender contact information is a second subset including the first subset and a first phone number, based on said user relationship indicating said receiving user is in a same enterprise as said sending user, and

the subset of the sender contact information includes the second subset and a second phone number, based on said user relationship indicating said receiving user individually is defined by said sending user.

2. The method of claim 1, wherein said communication system is a trusted communication system, said sending user is a trusted sending user, and said receiving user is a trusted receiving user.

3. The method of claim 1, wherein said security policy information further defines a user relationship including at least one of the group consisting of:

said receiving user globally being part of said communication system, and said receiving user having a friend-of-a-friend in common with said sending user.

4. The method of claim 2, wherein the security policy information restricts and permits release of each individual element of said sender contact information for each of a plurality of user relationships.

5. The method of claim 2, further comprising:

integrating a trusted list of contacts for said trusted receiving user into a contact management system.

6. The method of claim 5, wherein said electronic message is an e-mail message, and said contact management system is a mail user agent (MURA).

7. The method of claim 2, further comprising:

providing a public gateway for a non-user to access said contact database when said non-user receives said electronic message from said trusted sending user; and

representing said non-user as said trusted receiving user when said non-user requests said sender contact information.

8. The method of claim 7, further comprising:

indicating to said contact database that said non-user is accessing said contact database via said public gateway; and

restricting said sender contact information available to said non-user to a subset of said sender contact information based on an information policy defined by said trusted sending user.

9. The method of claim 1, further comprising:

locating cross-reference information for said sender contact information in an audit/token database prior to locating said sender contact information in said contact database, such that said cross-reference information locates said sender contact information in said contact database based on said sender identification token sent to said audit/token database.

10. The method of claim 1, further comprising:

creating said sender identification token using encoding techniques and technology.

11. The method of claim 10, wherein said encoding techniques and technology comprise utilizing at least one hash algorithm for a portion of the electronic message or the sender contact information.

12. The method of claim 1, wherein said sender identification token is embedded into a sub-portion of said electronic message.

13. The method of claim 12, wherein said sub-portion of said electronic message is at least one of the group consisting of:

a header portion of said electronic message, a body portion of said electronic message, and an attachment portion of said electronic message.

14. The method of claim 1, further comprising:

updating said sender contact information in a list of contacts for said receiving user when said sender contact information is changed at said contact database.

15. The method of claim 1, wherein said electronic message is at least one of the group consisting of:

an e-mail, a text message, an instant message, a telephone call, a voice over Internet protocol (VOIP) call, a voicemail, a facsimile, a file transfer, and a document archiving.

16. The method of claim 1, wherein said sender contact information further includes at least one of the group consisting of:

a name, a nick name, a postal address, an instant message address, a text message address, a facsimile number, an enterprise/company name, a job title, a photograph, an image, an avatar, a birthday, and contact information defined by the Internet Engineering Task Force (IETF) vcard standard.

17. The method of claim 1, wherein the first phone number is a business phone number, and the second phone number is a home phone number.

18. A system, comprising:

a computer that receives sender contact information and security policy information from a sending user, said security policy information defining a user relationship and a subset of said sender contact information, wherein

the computer sends an electronic message including a sender identification token to a receiving user, the sender identification token identifying said sending user,

in response to a reception of the electronic message from said sending user, the computer extracts, from the electronic message, the sender identification token, and

the computer receives a request including the sender identification token from the receiving user; and

the computer is configured to obtain, in response to the request, the subset of the sender contact information from a contact database, based on the sender identification token, to determine, in response to the request, said user relationship between the receiving user and the sending user, and to send the subset of the sender contact information, based on the security policy information and the user relationship,

the subset of the sender contact information is a first subset including an e-mail address of the sending user, based on said user relationship indicating said receiving user accesses said system via a publicly accessible gateway,

the subset of the sender contact information is a second subset including the first subset and a first phone number, based on said user relationship indicating said receiving user is in a same enterprise as said sending user, and

the subset of the sender contact information includes the second subset and a second phone number, based on said user relationship indicating said receiving user individually is defined by said sending user.

19. The system of claim 18, wherein the computer filters the electronic message from spam.

20. The system of claim 18, wherein said sender contact information includes contact information defined by the Internet Engineering Task Force vcard standard.
