Scalable searching of biometric databases using dynamic selection of data subsets
First Claim
1. A method of modifying a first biometric database, comprising:
- storing biometric data corresponding to a number of individuals in a second biometric database;
defining a subset of biometric records in the second biometric database by determining individuals scheduled to pass through a biometric acquisition device within a predefined time period, the determining being prior to the predefined time period, the biometric acquisition device linked with the first biometric database and located at or near one of;
an airport entry, a passenger terminal, a passenger security gate and a building entry;
transmitting, based on the determination and at a predetermined time prior to the predefined time period, the subset of biometric records associated with the predefined time period, to the first biometric database; and
deleting or modifying one or more biometric records from the first biometric database at a time indicated by a rule, the indicated time being after the predefined time period.

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.

10. A system for modifying a biometric database, the system comprising:
-
a first biometric database configured to store biometric records corresponding to a number of individuals; and a remote processor configured to; define a subset of the biometric records stored in the first biometric database by determining individuals scheduled to pass through a biometric acquisition device within a predefined time period, the determining being prior to the predefined time period, the biometric acquisition device linked with a second biometric database and located at or near one of;
an airport entry, a passenger terminal, a passenger security gate and a building entry; andtransmit, based on the determination and at a predetermined time prior to the predefined time period, the subset of biometric records associated with the predefined time period, to the second biometric database, wherein one or more biometric records from the second biometric database is deleted or modified at a time indicated by a rule, the indicated time being after the predefined time period. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
