Abstract

The invention relates to a system and method for tracking clients as they visit the locations of various recipients. Clients are provided with access to telephones and identification devices which the client uses to communicate with a remote computer. Information is communicated as to the clients location, the time of the clients visit to that location, and other types of information, such as to a service provided at the location. Location information may be provided by automatic number identification, wireless phone location information, or a global position device. The computer uses information received during the communication to identify and authenticate the client making the communication and the location of the client at the time of the communication. Authentication is accomplished by obtaining unique biometric parameters from a client and comparing those to biometric parameters in a database. Biometric data can include a voice print sample, or a finger or retinal print electronically transmitted to the remote computer. Because each of these identifiers results from a physiological characteristic which is unique to the client, the system assures that the identified client is the client making the communication.

Claims

1. A method for tracking a client, the method comprising the acts of:

receiving a phone call from the client;

receiving, from the client, a biometric identifier resulting from a unique physiological characteristic of the client;

comparing the biometric identifier with a client database correlating clients with their physiological characteristics; and

selecting which of the physiological characteristics corresponds to the client identifier to identify the client.

2. The method of claim 1, further comprising the act of:

identifying the client correlated with the selected physiological characteristic.

3. The method of claim 1, further comprising the act of:

identifying an origin of the phone call.

4. The method of claim 3, wherein the identifying act further comprises:

identifying a client geographic location of the phone call;

comparing the client geographic location with a database correlating addresses with geographic locations; and

selecting, from among the geographic locations included in the database, the geographic location which corresponds with the client geographic location.

5. The method of claim 3, wherein the identifying act further comprises:

receiving an ANI;

comparing the received ANI with a database correlating ANIs with addresses; and

selecting, from among the ANIs listed in the database, the address correlated with the received ANI.

6. The method of claim 1 wherein the act of comparing further comprises the act of:

receiving from the client a client identifier;

using the client identifier to define a subset of the client database; and

comparing the client identifier with the client identifiers in the subset of the client database.

7. The method of claim 6, wherein the client identifier is a code which is unique to the client.

8. The method of claim 6, wherein the client identifier is a code which is unique to an employer of the client.

9. The method of claim 1, wherein the biometric identifier corresponds to at least one of a group of biometric identifiers consisting of a voice pattern, a fingerprint pattern, an ear pattern, an iris pattern and retina pattern.

10. The method of claim 1, further comprising the act of:

identifying the address of the origin of the phone call.

11. The method of claim 1, further comprising the act of:

identifying the time of the phone call.

12. The method of claim 1, further comprising the act of:

identifying whether the client is arriving at or departing from the location where the phone call is placed.

13. The method of claim 1, wherein each physiological characteristics stored in the client database is a sample of a client identifier for the client correlated with the sample.

14. A method for tracking clients, the method comprising the acts of:

receiving a wireless phone call from a client;

identifying a client geographic location of the phone call;

comparing the client geographic location with a database correlating addresses with geographic locations; and

selecting, from among the geographic locations included in the database, the geographic location correlated with the client geographic location.

15. The method of claim 14, further comprising:

identifying the address correlated to the selected geographic location.

16. The method of claim 14, further comprising the act of:

identifying the client making the phone call.

17. The method of claim 16, wherein the act of identifying the client further comprises:

receiving, from the client, a client identifier resulting from a unique physiological characteristic of the client;

comparing the client identifier with a client database correlating clients with their physiological characteristics; and

selecting from the client database the physiological characteristic which corresponds to the received physiological characteristic so as to identify the client.

18. The method of claim 14, wherein the identifying act further comprises:

determining the geographic location of a plurality of receiving stations which are monitoring the phone call;

determining the range of the client from the at least two receivers; and

applying a triangulation calculation to the determined ranges and geographic locations to determine the client geographic location.

19. The method of claim 14, wherein the identifying act further comprises:

determining the geographic location of at least one receiving station monitoring the phone call;

determining the range of the client from the at least one receiving station; and

determining the orientation of the client relative to the at least one receiving station and calculating the client geographic location from the receiving station geographic location, the range and the orientation.

20. The method of claim 14, wherein the comparing act further comprises the act of:

calculating the distance between the client geographical location and at least one geographic location listed in the database.

21. The method of claim 14, wherein the selecting act further comprises:

identifying the geographic location listed in the database which is least far from the client geographic location.

22. The method of claim 14, further comprising the act of identifying the time of the phone call.

23. The method of claim 14, further comprising the act of:

identifying whether the client is arriving at or departing from the location where the phone call is placed.

24. A method for tracking a client, the method comprising the acts of:

receiving a phone call from a client;

receiving a biometric identifier from the client;

receiving a client identifier from the client; and

identifying the origin of the phone call.

25. The method of claim 24, wherein the biometric identifier results from a unique physiological characteristic of the client.

26. The method of claim 24, wherein the biometric identifier results from at least one of the group of biometric identifiers consisting of the client'"'"'s voice pattern, fingerprint pattern, ear pattern, iris pattern and retina pattern.

27. The method of claim 24, wherein the client identifier is a code which is unique to the client.

28. The method of claim 24, wherein the client identifier is a code which is unique to an employer of the client.

29. The method of claim 24, wherein the identifying act further comprises:

identifying a client geographic location of the phone call;

comparing the client geographic location with a database correlating addresses with geographic locations; and

selecting, from among the geographic locations included in the database, the geographic location which corresponds with the client geographic location.

30. The method of claim 24, wherein the identifying act further comprises:

receiving an ANI;

comparing the received ANI with a database correlating ANIs with addresses;

and selecting, from among the ANIs listed in the database, the address correlated with the received ANI.

31. The method of claim 24, further comprising the act of:

providing a client database which correlates clients with client identifiers and samples of client biometric identifiers.

32. The method of claim 31, wherein the client identifier is used to define a client database subset.

33. The method of claim 32, further comprising the act of:

comparing the biometric identifier with the client identifiers in the client database subset.
