Methods and systems for a voice ID verification database and service in social networking and commercial business transactions

1. A method of contact tracking comprising:

identifying whether a distance from a first device to a second device is less than a threshold value;

obtaining a contact time of when the distance was less than the threshold value;

obtaining contact information and location information of the first device at the contact time;

adding the contact and location information and the contact time to a contact list, where the contact list is stored in computer memory of the second device; and

measuring an acoustic environment about the second device for a time segment, where the contact time is within the time segment, and wherein the second device does the measuring.

2. The method according to claim 1 , further including the step of:

obtaining second location information from the second device.

3. The method according to claim 2 , further including the step of:

time matching the location information with the second location information.

4. The method according to claim 3 , wherein the step of identifying whether the distance is less than the threshold value is accomplished by calculating the difference between the location information and the second location information and checking if the difference is less than the threshold value.

5. The method according to claim 4 , further including the step of:

setting a positive notification value if the distance is less than the threshold value.

6. The method according to claim 4 , further including the step of:

setting a negative notification value if the distance is not less than the threshold value.

7. The method according to claim 5 , further including the step of:

sending a positive notification signal.

8. The method according to claim 7 , further including the step of:

sending a notification message to the second device.

9. The method according to claim 4 , where the second device is at least one of an earphone, a phone, or a computer.

10. The method according to claim 9 , where the threshold value is between 1 ft and 30 ft.

11. The method according to claim 10 , further including the step of:

obtaining acoustic information from the measured acoustic environment.

12. The method according to claim 11 , further including the step of:

identifying an acoustic segment of the acoustic information within a time of interest.

13. The method according to claim 12 , further including the step of:

obtaining acoustic characteristics of the acoustic segment.

14. The method according to claim 13 , further including the step of:

comparing the acoustic characteristics with stored voiceprints to identify contact information associated with the first device.

15. The method according to claim 14 , further including the step of:

sending the contact list wirelessly to a computer.
