Abstract

Disclosed is a method of indexing a first database of records. A fingerprint is received and a biometric identification number is determined based thereon. A database is formed and is indexed based on the biometric identification number. As such, absent knowledge of the actual index value, the index is reconstructable based on a provided fingerprint data.

Claims

1. A method of indexing a first database of records comprising:

receiving biometric information of an individual;

processing the biometric information of the individual to determine a biometric identification number, the biometric identification number derived from the biometric information;

receiving personal data relating to the individual;

storing within at least a first field within a record the personal data and within at least a second field within the record the biometric identification number; and

,

indexing the records within the database based on data within the at least a second field.

2. A method according to claim 1, wherein some of the data within a record including the biometric identification number is recorded on a portable storage medium, the biometric identification number recorded in a machine readable form.

3. A method according to claim 2, wherein the personal storage medium is an identification card.

4. A method according to claim 3, wherein the machine readable form is a barcode.

5. A method according to claim 1, wherein the biometric information comprises a fingerprint.

6. A method according to claim 5, wherein the biometric identification number is a number determined through an analysis of features within the fingerprint, the number resulting from the analysis.

7. A method according to claim 6, wherein the number is approximately a same number for a same provided fingerprint regardless of the angle of acquisition of said fingerprint.

8. A method according to claim 5, wherein the number is indicative of some features within the fingerprint, the features selected for repeatable extraction, reliability, and in such a fashion as to provide an approximately unique result.

9. A method according to claim 1, wherein at least some records of the first database include biometric data relating to biometric samples of individuals and comprising:

providing a second database comprising a plurality of records at least some records including biometric data relating to biometric samples of individuals; and

,

correlating the biometric data within the first database and the biometric data within the second database to identify records pertaining to a same individual.

10. A method according to claim 9, comprising when biometric data within the first database and the biometric data within the second database pertain to a same individual, flagging a record associated with the same individual within the first database.

11. A method according to claim 1, wherein the biometric identification number is repeatably and approximately stably derived from the biometric information.

12. A method according to claim 11, wherein the biometric information comprises a fingerprint.

33. A method according to claim 3, comprising comparing biometric template data stored within the portable storage medium with the received biometric information of the individual.

13. A system comprising:

a biometric transducer for receiving biometric information of an individual; and

,

a processor

for processing the biometric information of the individual to determine a biometric identification number, the biometric identification number derived from the biometric information,

for receiving personal data relating of the individual,

for storing within at least a first field within a record of a first database the personal data and within at least a second field within the record of the first database the biometric identification number and,

for indexing the records within the first database based on data within the at least a second field.

14. A system according to claim 13, wherein the biometric transducer comprises a fingerprint imager.

15. A system according to claim 13, wherein the biometric identification number is determined in an approximately stable fashion.

16. A system according to claim 15, wherein the biometric transducer is a fingerprint transducer.

17. A system according to claim 16, wherein the fingerprint transducer is an optical fingerprint sensor.

18. A system according to claim 13, wherein at least some records of the first database include biometric data relating to biometric samples of individuals and comprising:

a second database comprising a plurality of records at least some records including biometric data relating to biometric samples of individuals; and

wherein the processor is for correlating the biometric data within the first database and the biometric data within the second database to identify records pertaining to a same individual.

19. A system according to claim 18, wherein the biometric transducer is a fingerprint optical scanner.

20. A data record comprising:

a plurality of data fields; and

an index field for use in indexing of a plurality of data records having index data stored therein, the index data, approximately stably derived from at least one live fingerprint of a same finger tip of an individual.

21. A method of indexing a first database of records comprising:

receiving biometric information of an individual;

obtaining a biometric identification number that is based upon same biometric information of the individual;

retrieving a record from an indexed database of records, using an index based on the biometric identification number; and

,

authenticating the individual based upon a comparison of the received biometric information and biometric template information stored within the indexed database.

22. A method according to claim 21, wherein obtaining comprises determining the biometric identification number that is based upon same biometric information of the individual.

23. A method according to claim 22, wherein further data within the retrieved record is used in authenticating the individual.

24. A method according to claim 22, wherein authenticating is performed on a local workstation, the local workstation other than a server hosting the database of records.

25. A method according to claim 21, comprising:

receiving personal data relating to the individual,

wherein determining the biometric identification number comprises determining an extended biometric identification number based upon same biometric information of the individual and based upon the personal data.

26. A method according to claim 22, wherein the index is the biometric identification number.

27. A method according to claim 21, wherein obtaining comprises reading the biometric identification number from a portable storage medium.

28. A method according to claim 27, comprising verifying data stored within the portable storage medium against data retrieved from the database of records.

29. A method according to claim 27, wherein authenticating is performed on a local workstation, the local workstation other than a server hosting the database of records.

30. A method according to claim 27, wherein the biometric identification number includes a signature for verifying an authenticity of the biometric identification number.

31. A method according to claim 30, wherein the signature includes time data for forming a time stamp.

32. A method according to claim 27, comprising comparing biometric template data stored within the portable storage medium with the received biometric information of the individual.
