Degrees of separation for handling communications
View Patent ↗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. For example, a recipient may know a first user (first degree of separation) and the first user may know a second user (second degree of separation) who knows the sender of an e-mail. In this case, the sender is separated from the recipient by two degrees of separation (by two other contact). 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 are evaluated to determine the number of degrees (or hops) are required to link or relate two users.
1. A computer-implemented method comprising:
receiving a communication from a sender, wherein the communication is directed to an intended recipient;
accessing a contact list associated with the intended recipient, the contact list of the intended recipient identifying at least one user identifier;
accessing a contact list associated with the at least one user identifier;
determining, based on the contact list of the intended recipient and the contact list of the at least one user identifier, whether the sender and the intended recipient are linked by less than a threshold number of degrees of separation; and
determining, using at least one processor, whether the communication is a spam communication based on whether the sender and the intended recipient are linked by less than the threshold number of degrees of separation.
2. The method of claim 1 , further comprising:
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.
3. The method of claim 2 , wherein the interface informs the intended recipient that the sender has sent a communication to the intended recipient.
4. The method of claim 2 , wherein the interface comprises an interface element that allows the intended recipient 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 , further comprising:
displaying the communication to the intended recipient when the sender and the intended recipient are linked by less than the threshold number of degrees of separation.
7. The method of claim 1 , wherein the contact list of the intended recipient comprises at least one of an address book, a buddy list, a personal phone book, or a white list.
8. The method of claim 1 , wherein the communication is one of an email message, an instant message, an SMS message, or a telephone call.
9. The method of claim 1 , further comprising:
displaying the communication to the intended recipient when the threshold number of degrees of separation corresponds to a value of at least one and when the contact list of the user identifier includes an identifier of the sender.
10. The method of claim 1 , further comprising:
displaying an interface to the intended recipient, prior to displaying the communication to the intended recipient, when the threshold number of degrees of separation corresponds to a value of at least two and when an identifier of the sender is not included in the contact list of the intended recipient and the contact list of the user identifier.
11. A non-transitory computer-readable storage medium storing programmable instructions, which when executed by at least one processor, causes the processor to perform a method comprising:
receiving a communication from a sender, wherein the communication is directed to an intended recipient;
accessing a contact list associated with the intended recipient, the contact list of the intended recipient identifying at least one user identifier;
accessing a contact list associated with the at least one user identifier;
determining, based on the contact list of the intended recipient and the contact list of the at least one user identifier, whether the sender and the intended recipient are linked by less than a threshold number of degrees of separation; and
determining, using at least one processor, whether the communication is a spam communication based on whether the sender and the intended recipient are linked by less than the threshold number of degrees of separation.
12. The non-transitory computer-readable storage medium of claim 11 , wherein the programmable instructions further cause the at least one processor to perform the following step:
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.
13. The non-transitory computer-readable storage medium of claim 12 , wherein the interface is displayed to the intended recipient when the threshold number of degrees of separation corresponds to a value of at least two and when an identifier of the sender is not included in the contact list of the intended recipient and the contact list of the user identifier.
14. The non-transitory computer-readable storage medium of claim 13 , wherein the interface comprises an interface element that allows the intended recipient to indicate that the communication should be displayed.
15. The non-transitory computer-readable storage medium of claim 11 , wherein the programmable instructions further cause the at least one processor to perform the following step:
displaying the communication to the intended recipient when the sender and the intended recipient are linked by less than the threshold number of degrees of separation.
16. The non-transitory computer-readable storage medium of claim 11 , wherein the contact list of the intended recipient comprises at least one of an address book, a buddy list, a personal phone book, or a white list.
17. The non-transitory computer-readable storage medium of claim 11 , wherein the communication is one of an e-mail message, an instant message, an SMS message, or a telephone call.
18. An apparatus comprising:
a memory device storing instructions;
at least one processor executing the instructions to:
receive a communication from a sender, wherein the communication is directed to an intended recipient;
access a contact list associated with the intended recipient, the contact list of the intended recipient identifying at least one user identifier;
access a contact list associated with the at least one user identifier;
determine, based on the contact list of the intended recipient and the contact list of the at least one user identifier, whether the sender and the intended recipient are linked by less than a threshold number of degrees of separation; and
determine whether the communication is a spam communication based on whether the sender and the intended recipient are linked by less than the threshold number of degrees of separation.
19. The apparatus of claim 18 , wherein the communication is displayed to the intended recipient when the threshold number of degrees of separation corresponds to a value of at least one and when the contact list of the user identifier includes an identifier of the sender.
20. The apparatus of claim 18 , wherein the at least one processor is further adapted to:
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.
