Abstract

Messaging patterns for a plurality of subscribers are obtained and analyzed to determine a “trust score” that is an indication of the likelihood that a given message for a particular subscriber is of interest, as opposed to unwanted, e.g., spam or telemarketing phone calls. Subscribers establish or set trust score thresholds and call processing actions to take based on the thresholds and the trust score for a given incoming communication. For example, if a subscriber establishes a processing action of “block call” for calls with a “low” threshold trust score, and an incoming message (email, SMS, instant message, or phone call) has a trust score of “low” or “very low”, the message is blocked. Conversely, if the trust score for the message is “high” and the user has specified to pass through “high” trust score messages, the message is passed through. Various algorithms can be used compute trust scores based on messaging patterns.

Claims

1. A method for processing an incoming message for delivery to a recipient, the message originating from a source, comprising the steps of:

a) determining a trust score for said incoming message based on a messaging pattern of messages from the source, the messaging pattern comprising data relating to the following;

(1) a number of messages sent by the source, (2) a number of messages received by the source, (3) where the message is a phone call an average length of phone calls made by the source, (4) where the message is a phone call an average length of phone calls received by the source, (5) where the message is an electronic message a ratio of electronic messages sent by the source to electronic messages received by the source;

b) obtaining at least one threshold trust score based on a type of the incoming message, said threshold trust score being associated with a message processing instruction; and

c) performing processing of said incoming message in accordance with said trust score, said threshold trust score and said associated message processing instruction.

2. The method of claim 1, wherein step a) comprises the steps of identifying the source of said incoming message and obtaining a trust score for said source, and using the trust score of the source as the trust score for the incoming message.

3. The method of claim 1, wherein said trust score is calculated in advance of a time of receipt of said incoming message and thus independent of content of the incoming message.

4. The method of claim 1, wherein said trust score is stored in a central database.

5. The method of claim 1, wherein said incoming message comprises an electronic message and wherein said trust score is obtained from a messaging pattern of the source of the incoming electronic message.

6. The method of claim 5, wherein said incoming electronic message comprises an email message.

7. The method of claim 1, wherein said incoming message comprises a phone call.

8. The method of claim 1 wherein messaging patterns are tracked for a plurality of subscribers to a common telecommunications service, said plurality of subscribers including said recipient, wherein trust scores are determined based on messaging patterns of said subscribers, wherein the source of said incoming message comprises a subscriber in said plurality of subscribers, and wherein step a) is performed by calculation of the trust scores prior to a time of transmission of said incoming message.

9. The method of claim 1, wherein the data further includes (6) contents of an electronic address book for a plurality of subscribers.

10. The method of claim 1, wherein the data includes, for an electronic message, a mean length of response messages to previous messages from the source.

11. The method of claim 1, wherein said trust score comprises a numerical index and wherein said threshold trust score comprises a numerical index.

12. A method for filtering a message from a first party to a second party, comprising the steps of:

a) obtaining messaging patterns for a plurality of parties, said plurality of parties including said first party, and the messaging patterns comprising data relating to (1) a number of messages sent, (2) a number of messages received, (3) where the message is a phone call an average length of phone calls made, (4) where the message is a phone call an average length of phone calls received, (5) where the message is an electronic message a ratio of electronic messages sent to electronic messages received;

b) deriving, from said messaging patterns, a trust score for each of said parties in said plurality of parties, wherein the trust score is derived independently and in advance of the receipt of the message from the first party to the second party;

c) comparing the trust score for said first party to a threshold trust score specified by the second party, the threshold trust score being based on a type of the message; and

d) filtering the message in accordance with instructions from said second party and the results of the comparison at step c).

13. The method of claim 12, wherein said first and second parties are subscribers to a common telecommunications service provider service.

14. The method of claim 12, wherein said messaging patterns comprise patterns of the number of electronic messages sent and received by said plurality of parties.

15. The method of claim 12, wherein said messaging patterns comprise patterns of phone calls and include at least one of:

phone call length per call, number of phone calls made, number of phone calls received, and ratio of phone calls made to phone calls received.

16. The method of claim 12, wherein said trust score comprises a numerical index and wherein said threshold trust score comprises a numerical index.

17. The method of claim 12, wherein said step of filtering comprises the step of blocking said communication if said trust score is below the threshold trust score.

18. A network apparatus for use in processing a message directed to a subscriber in accordance with instructions from said subscriber, wherein a source of said message is assigned a trust score;

said network apparatus comprising;

a database of trust scores for a plurality of subscribers based upon messaging patterns of the subscribers, the messaging patterns including statistical data pertaining to messages sent and received by the subscribers, and the messaging patterns comprising data relating to (1) a number of messages sent, (2) a number of messages received, (3) where the message is a phone call an average length of phone calls made, (4) where the message is a phone call an average length of phone calls received, (5) where the message is an electronic message a ratio of electronic messages sent to electronic messages received;

a machine readable storage medium storing a threshold trust score from said subscriber, said threshold trust score being associated with a processing instruction and based on a type of message; and

a processing system comparing said trust score assigned to said source with said threshold trust score and responsively processing said message in accordance with said comparison and the processing instruction associated with said threshold trust score.

19. The network apparatus of claim 18, wherein said processing system compares trust scores assigned to messages directed to said plurality of subscribers with threshold trust scores from said plurality of subscribers and responsively processing said messages in accordance with said comparison and processing instructions associated with said threshold trust scores.

20. The network apparatus of claim 18, wherein said threshold trust score comprising a numerical index.

21. The network apparatus of claim 18, wherein said message comprises an electronic message.

22. The network apparatus of claim 18, wherein said message comprises a phone call.
