Abstract

A sender'"'"'s degrees of separation from a recipient may be used to aid in spam filtering or to otherwise handle a communication. The “degrees of separation” represent a metric used to quantify whether/how the recipient is linked to the sender through intermediary people or other entities. A level of “trust” or “legitimacy” about a sender'"'"'s communication can be inferred by looking at whether the sender is linked to an intended recipient. Typically, user contact lists (e.g., address book, buddy list, and/or white list) are evaluated to determine the number of degrees (or hops) are required to link or relate two users.

Claims

1. A method for handling a communication from a sender to an intended recipient, the method comprising:

receiving a communication from a sender, wherein the communication is directed to an intended recipient;

identifying the sender of the communication;

identifying the intended recipient of the communication;

accessing a contact list of the intended recipient, the contact list of the intended recipient being maintained in association with a different form of communication than the communication from the sender to the intended recipient and including at least a first user identifier associated with the different form of communication;

accessing a contact list of the first user identifier, the contact list of the first user identifier including at least a second user identifier;

determining, based in part on the accessed first contact list and the accessed second contact list, whether the sender and the intended recipient are linked by less than a threshold number of degrees of separation; and

displaying an interface to the intended recipient prior to displaying the communication to the intended recipient when the sender and the intended recipient are not linked by less than the threshold number of degrees of separation, wherein the interface comprises an interface element that allows the intended recipient to indicate that the communication should be displayed.

2. The method of claim 1 wherein the interface informs the intended recipient that the sender has sent a communication to the intended recipient.

3. The method of claim 1 wherein the interface displays to the intended recipient an identifier of the sender.

4. The method of claim 1 further comprising displaying the communication when the intended recipient uses the interface element to indicate that the communication should be displayed.

5. The method of claim 1 wherein determining whether the sender and the intended recipient are linked by less than the threshold number of degrees of separation includes determining whether the sender and the intended recipient are linked by at least one intermediary entity.

6. The method of claim 1 wherein the contact list of the first user identifier is maintained is association with the type of communication that includes the communication from the sender to the recipient.

7. The method of claim 1 wherein the contact list of the intended recipient comprises an address book.

8. The method of claim 1 wherein the contact list of the intended recipient comprises a buddy list.

9. The method of claim 1 wherein the contact list of the intended recipient comprises a personal phone book.

10. The method of claim 1 wherein the contact list of the intended recipient comprises a white list.

11. The method of claim 1 wherein the communication is an e-mail message.

12. The method of claim 1 wherein the communication is an instant message.

13. The method of claim 1 wherein the communication is an SMS message.

14. The method of claim 1 wherein the communication is a telephone call.

15. A computer-usable medium storing a computer program for handling a communication from a sender to an intended recipient, the computer program comprising instructions for causing a computer to:

receive a communication from a sender, wherein the communication is directed to an intended recipient;

identify the sender of the communication;

identify the intended recipient of the communication;

access a contact list of the intended recipient, the contact list of the intended recipient being maintained in association with a different form of communication than the communication from the sender to the intended recipient and including at least a first user identifier associated with the different form of communication;

access a contact list of the first user identifier, the contact list of the first user identifier including at least a second user identifier;

determine, based in part on the accessed first contact list and the accessed second contact list, whether the sender and the intended recipient are linked by less than a threshold number of degrees of separation; and

display an interface to the intended recipient prior to displaying the communication to the intended recipient when the sender and the intended recipient are not linked by less than the threshold number of degrees of separation, wherein the interface comprises an interface element that allows the intended recipient to indicate that the communication should be displayed.

16. The medium of claim 15 wherein the interface informs the intended recipient that the sender has sent a communication to the intended recipient.

17. The medium of claim 15 wherein the interface displays to the intended recipient an identifier of the sender.

18. The medium of claim 15 further comprising displaying the communication when the intended recipient uses the interface element to indicate that the communication should be displayed.

19. The medium of claim 15 wherein, to determine whether the sender and the intended recipient are linked by less than the threshold number of degrees of separation, the computer program further comprises instructions for causing a computer to determine whether the sender and the intended recipient are linked by at least one intermediary entity.

20. The medium of claim 15 wherein, the contact list of the first user identifier is maintained is association with the type of communication that includes the communication from the sender to the recipient.

21. The medium of claim 15 wherein the contact list of the intended recipient comprises an address book.

22. The medium of claim 15 wherein the contact list of the intended recipient comprises a buddy list.

23. The medium of claim 15 wherein the contact list of the intended recipient comprises a personal phone book.

24. The medium of claim 15 wherein the contact list of the intended recipient comprises a white list.

25. The medium of claim 15 wherein the communication is an e-mail message.

26. The medium of claim 15 wherein the communication is an instant message.

27. The medium of claim 15 wherein the communication is an SMS message.

28. The medium of claim 15 wherein the communication is a telephone call.
