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, via a processor, a threshold of match certainty associated with an identity of a first person communicating with a second person in a first audio communication via a communication network, wherein the threshold of match certainty relates to whether a voiceprint matches voice characteristics of the first person;

dynamically adjusting, via the processor, the threshold of match certainty based on data external to the first audio communication, the data also being external to the voiceprint, to yield an adjusted threshold of match certainty, wherein the adjusted threshold of match certainty defines factors which, if met, cause initiation of tracking of the first person; and

when the factors are met, initiating, via a tracking module, electronic tracking of the first person to identify the first person in a second audio communication initiated after the first audio communication.

2. The method of claim 1, wherein the adjusted threshold of match certainty is based on one of a location of the first person, a location of the second person, a phone number, a device associated with the first person, a time of day, a content of the first audio communication, and an information profile.

3. The method of claim 1, further comprising fine-tuning the data external to the first audio communication based on a relationship between the first person and the second person.

4. The method of claim 1, further comprising storing the first audio communication in a database.

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

6. The method of claim 1, further comprising storing additional external data associated with the first audio communication, 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 second person, and the first person.

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

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 threshold of match certainty associated with an identity of a first person communicating with a second person in a first audio communication via a communication network, wherein the threshold of match certainty relates to whether a voiceprint matches voice characteristics of the first person;

dynamically adjusting the threshold of match certainty based on data external to the first audio communication, the data also being external to the voiceprint, to yield an adjusted threshold of match certainty, wherein the adjusted threshold of match certainty defines factors which, if met, cause initiation of tracking of the first person; and

when the factors are met, initiating, via a tracking module, electronic tracking of the first person to identify the first person in a second audio communication initiated after the first audio communication.

9. The system of claim 8, wherein the adjusted threshold of match certainty is based on one of a location of the first person, a phone number, a device associated with the first person, a time of day, a content of the first audio communication, an information profile, and the second person.

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 first audio communication based on a relationship between the first person and the second person.

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 first audio communication in a database.

12. The system of claim 11, wherein the data external to the first audio communication 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 first audio communication, 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 second person, and the first person.

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

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 threshold of match certainty associated with an identity of a first person communicating with a second person in a first audio communication via a communication network, wherein the threshold of match certainty relates to whether a voiceprint matches voice characteristics of the first person;

dynamically adjusting the threshold of match certainty based on data external to the first audio communication, the data also being external to the voiceprint, to yield an adjusted threshold of match certainty, wherein the adjusted threshold of match certainty defines factors which, if met, cause initiation of tracking of the first person; and

when the factors are met, initiating, via a tracking module, electronic tracking of the first person to identify the first person in a second audio communication initiated after the first audio communication.

16. The computer-readable storage device of claim 15, wherein the adjusted threshold of match certainty is based on one of a location of the first person, a phone number, a device associated with the first person, a time of day, a content of the first audio communication, an information profile, and the second person.

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 first audio communication based on a relationship between the first person and the second person.

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 first audio communication in a database.

19. The computer-readable storage device of claim 18, wherein the data external to the first audio communication 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 first audio communication, 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 second person, and the first person.
