Abstract

A method of searching a biometric database includes storing biometric data corresponding to a number of users in a database, and defining one or more data subsets in the database according to inputs from users expecting to pass through a given biometric acquisition device that is linked with the database within a certain time period. A search initiated by the given acquisition device at a given time is then scaled down to only those data subsets defined by the inputs from those users expecting to pass through the acquisition device at the given time. This modification of the database and database search is performed continuously and automatically based on dynamic information provided by other automatic and/or manual systems, and then optionally the information on the databases can be automatically modified or deleted based either on a biometric match result or based on rules encoded in the database records.

Claims

1-3. -3. (canceled)

4. A method of modifying a first biometric database, comprising:

storing biometric data corresponding to a number of individuals in a second database;

defining a subset of biometric records in the second database based on individuals expecting to pass through a given biometric acquisition device within a predefined time period, the biometric acquisition device linked with the first database and located at or near one of;

an airport entry, a passenger terminal, a passenger security gate and a building entry;

transmitting the subset of biometric records to the first database; and

if an individual is not biometrically-matched within the predefined time period, deleting a corresponding biometric record from the first database.

5. The method of claim 4, wherein defining the subset comprises defining the subset based on a user dialing from a phone number, sending an email, sending a text message or entering information at a web page.

6. The method of claim 4, wherein defining the subset comprises defining the subset based at least in part on one or more of:

a name or identifier of an individual, a flight number, a flight time, a gate number, an itinerary identifier and a location of the biometric acquisition device.

7. The method of claim 4, further comprising flagging the individual'"'"'s biometric record for defining the subset based on one of:

the individual'"'"'s originating phone number, and an identifier associated with the individual or sent to the individual.

8. The method of claim 7, further comprising flagging the individual'"'"'s biometric record based on an identifier sent to the individual via an email or text message.

9. The method of claim 4, wherein transmitting the subset comprises transmitting the subset based on at least one rule specifying one or more of:

a condition, a time, and a destination database for transmitting the subset.

10. The method of claim 4, further comprising deleting one or more biometric records in the first database responsive to biometric matching using information stored in one or more fields of the biometric record.

11. The method of claim 4, wherein deleting the biometric record comprises deleting the biometric record based on at least one rule associated with the biometric record specifying one or more of:

a condition and a time for deleting the biometric record.

12. The method of claim 4, wherein deleting the biometric record comprises deleting the biometric record responsive to departure of the individual'"'"'s flight.

13. A method of modifying a first biometric database, comprising:

storing biometric data corresponding to a number of individuals in a first database;

defining a subset of biometric records in the first database based on individuals expecting to pass through a given biometric acquisition device within a predefined time period, the biometric acquisition device linked with the first database and located at or near one of;

an airport entry, a passenger terminal, a passenger security gate and a building entry;

searching within the defined subset of biometric records responsive to an individual passing through the biometric acquisition device within the predefined time period; and

if one of the expected individuals is not biometrically-matched within the predefined time period, deleting or moving a corresponding biometric record from the subset.

14. The method of claim 13, wherein defining the subset comprises defining the subset based on a user dialing from a phone number, sending an email, sending a text message or entering information at a web page.

15. The method of claim 13, wherein defining the subset comprises defining the subset based at least in part on one or more of:

a name or identifier of an individual, a flight number, a flight time, a gate number, an itinerary identifier and a location of the biometric acquisition device.

16. The method of claim 13, further comprising flagging the individual'"'"'s biometric record for defining the subset, based on one of:

the individual'"'"'s originating phone number, and an identifier associated with the individual or sent to the individual.

17. The method of claim 16, further comprising flagging the individual'"'"'s biometric record based on an identifier sent to the individual via an email or text message.

18. The method of claim 13, further comprising deleting or moving one or more biometric records from the subset responsive to biometric matching using information stored in one or more fields of the biometric record.

19. The method of claim 13, further comprising deleting or moving one or more biometric records from the subset based on at least one rule associated with the subset, the at least one rule specifying one or more of:

a condition and a time for deleting the one or more biometric records.

20. The method of claim 13, further comprising deleting or moving one or more biometric records from the subset responsive to one or more corresponding individuals passing the biometric acquisition device or departure of a corresponding flight.

21. A method of modifying a first biometric database, comprising:

storing biometric data corresponding to a number of individuals in a first database;

defining a subset of biometric records in the first database based on individuals expecting to pass through a given biometric acquisition device within a predefined time period, the biometric acquisition device linked with the first database and located at or near one of;

an airport entry, a passenger terminal, a passenger security gate and a building entry;

searching within the defined subset of biometric records responsive to an individual passing through the biometric acquisition device within the predefined time period; and

deleting or moving a biometric record from the subset responsive to biometric matching using information stored in one or more fields of the biometric record.

22. The method of claim 21, wherein defining the subset comprises defining the subset based on a user dialing from a phone number, sending an email, sending a text message or entering information at a web page.

23. The method of claim 21, wherein defining the subset comprises defining the subset based at least in part on one or more of:

a name or identifier of an individual, a flight number, a flight time, a gate number, an itinerary identifier and a location of the biometric acquisition device.

24. The method of claim 21, further comprising flagging the individual'"'"'s biometric record for defining the subset, based on one of:

the individual'"'"'s originating phone number, and an identifier associated with the individual or sent to the individual.

25. The method of claim 21, further comprising flagging the individual'"'"'s biometric record based on an identifier sent to the individual via an email or text message.

26. The method of claim 21, further comprising deleting or moving one or more biometric records from the subset based on at least one rule associated with the subset, the at least one rule specifying one or more of:

a condition and a time for deleting the one or more biometric records.

27. The method of claim 21, further comprising deleting or moving one or more biometric records from the subset responsive to one or more corresponding individuals passing the biometric acquisition device or departure of a corresponding flight.
