Abstract

Disclosed are systems, methods, and computer readable media for tracking a person of interest. The method embodiment comprises identifying a person of interest, capturing a voiceprint of the person of interest, comparing a received voiceprint of a caller with the voiceprint of the person of interest, and tracking the caller if the voiceprint of the caller is a substantial match to the voiceprint of the person of interest.

Claims

1. A method comprising:

establishing a tracking threshold based on a relationship between a caller and a call recipient conversing on a call;

establishing a level of certainty associated with an identity of the caller;

automatically adjusting, via a processor, the tracking threshold based on data external to the call, to yield an adjusted threshold; and

when the level of certainty meets the adjusted threshold, electronically tracking the caller.

2. The method of claim 1, wherein the level of certainty is based on one of a location of the caller, a phone number, a device associated with the caller, a time of day, a content of the call, an information profile, and a person communicating with the caller.

3. The method of claim 1, further comprising fine-tuning the data external to the call based on the relationship.

4. The method of claim 1, further comprising storing the call in a database.

5. The method of claim 4, wherein the data external to the call is also stored in the database.

6. The method of claim 1, further comprising storing additional external data associated with the call, wherein the additional external data comprises one of a content, a transcription, a duration, a time of day, a location, a device, a rate of movement, a phone number, a button pressed, an ambient noise, the call recipient, and the caller.

7. The method of claim 1, wherein the tracking of the caller is performed by recording information associated with a communication device used by the caller.

8. A system comprising:

a processor; and

a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising;

establishing a tracking threshold based on a relationship between a caller and a call recipient conversing on a call;

establishing a level of certainty associated with an identity of the caller;

automatically adjusting the tracking threshold based on data external to the call, to yield an adjusted threshold; and

when the level of certainty meets the adjusted threshold, electronically tracking the caller.

9. The system of claim 8, wherein the level of certainty is based on one of a location of the caller, a phone number, a device associated with the caller, a time of day, a content of the call, an information profile, and a person communicating with the caller.

10. The system of claim 8, the computer-readable storage medium having instructions stored which, when executed by the processor, result in operations comprising fine-tuning the data external to the call based on the relationship.

11. The system of claim 8, the computer-readable storage medium having instructions stored which, when executed by the processor, result in operations comprising storing the call in a database.

12. The system of claim 11, wherein the data external to the call is also stored in the database.

13. The system of claim 8, the computer-readable storage medium having instructions stored which, when executed by the processor, result in operations comprising storing additional external data associated with the call, wherein the additional external data comprises one of a content, a transcription, a duration, a time of day, a location, a device, a rate of movement, a phone number, a button pressed, an ambient noise, the call recipient, and the caller.

14. The system of claim 8, wherein the tracking of the caller is performed by recording information associated with a communication device used by the caller.

15. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:

establishing a tracking threshold based on a relationship between a caller and a call recipient conversing on a call;

establishing a level of certainty associated with an identity of the caller;

automatically adjusting the tracking threshold based on data external to the call, to yield an adjusted threshold; and

when the level of certainty meets the adjusted threshold, electronically tracking the caller.

16. The computer-readable storage device of claim 15, wherein the level of certainty is based on one of a location of the caller, a phone number, a device associated with the caller, a time of day, a content of the call, an information profile, and a person communicating with the caller.

17. The computer-readable storage device of claim 15, having instructions stored which, when executed by the computing device, result in operations comprising fine-tuning the data external to the call based on the relationship.

18. The computer-readable storage device of claim 15, having instructions stored which, when executed by the computing device, result in operations comprising storing the call in a database.

19. The computer-readable storage device of claim 18, wherein the data external to the call is also stored in the database.

20. The computer-readable storage device of claim 15, having instructions stored which, when executed by the computing device, result in operations further comprising storing additional external data associated with the call, wherein the additional external data comprises one of a content, a transcription, a duration, a time of day, a location, a device, a rate of movement, a phone number, a button pressed, an ambient noise, the call recipient, and the caller.
