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

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

defining one or more data subsets in the second database based on users expecting to pass through a given biometric acquisition device within a certain time period, the biometric acquisition device linked with the first database and located at or near one of;

an airport entry, a passenger boarding gate and a building entry;

transmitting the data subsets from the second database to the first database; and

deleting one or more records in the first database in response to biometric matching using information stored in one or more fields of the one or more biometric records.

2. The method of claim 1, wherein storing biometric data comprises storing iris data.

3. The method of claim 1, further comprising defining one or more data subsets in the second database based on a user dialing a phone number, sending an email, sending a text message or entering information at a web page.

4. The method of claim 3, further comprising identifying the user based on an originating phone number or identifier of the user.

5. The method of claim 4, further comprising flagging the user'"'"'s biometric record for the one or more data subsets based on the originating phone number or identifier of the user.

6. The method of claim 1, further comprising defining one or more data subsets in the second database based in part on one or more of:

passenger name, flight number, flight time, gate number, itinerary identifier and location of the biometric acquisition device.

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

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

defining one or more data subsets in the second database based on users expecting to pass through a given biometric acquisition device within a certain time period, the biometric acquisition device linked with the first database;

transmitting the data subsets from the second database to the first database;

deleting one or more records in the first database in response to biometric matching using information stored in one or more fields of the one or more biometric records; and

deleting one or more records in the first database when an associated flight has departed from where the biometric acquisition device is located.

8. A system for modifying a biometric database, comprising:

a biometric acquisition device located at or near one of;

an airport entry, a passenger boarding gate and a building entry;

a first database linked to the biometric acquisition device; and

a second database storing biometric data corresponding to a number of users, from which one or more data subsets are defined based on users expecting to pass through the biometric acquisition device within a certain time period, the second database transmitting the one or more data subsets to the first database,

wherein one or more records are deleted in the first database in response to biometric matching using information stored in one or more fields of the one or more biometric records.

9. The system of claim 8, wherein second database stores biometric data that comprises iris data.

10. The system of claim 8, wherein the one or more data subsets in the second database are defined based on a user dialing a phone number, sending an email, sending a text message or entering information at a web page.

11. The system of claim 10, wherein the one or more data subsets in the second database are defined based on an originating phone number or identifier of the user.

12. The system of claim 8, further comprising a departure control system.

13. The system of claim 8, wherein the one or more data subsets in the second database are defined based in part on one or more of:

passenger name, flight number, flight time, gate number, itinerary identifier and location of the biometric acquisition device.

14. A system for modifying a biometric database, comprising:

a biometric acquisition device;

a first database linked to the biometric acquisition device; and

a second database storing biometric data corresponding to a number of users, from which one or more data subsets are defined based on users expecting to pass through the biometric acquisition device within a certain time period, the second database transmitting the one or more data subsets to the first database,

wherein one or more records in the first database are deleted in response to biometric matching using information stored in one or more fields of the one or more biometric records,

wherein one or more records in the first database are deleted when an associated flight has departed from where the biometric acquisition device is located.
