Patent ID: 8832124

Claim:
A method comprising: receiving, by a processing device, a first input biometric sample associated with an individual and a second input biometric sample associated with the individual; determining, by the processing device, one or more first characteristics associated with the first input biometric sample and one or more second characteristics associated with the second input biometric sample; grouping, by the processing device and after receiving the first input biometric sample and the second input biometric sample, a plurality of records to form a first set of records and a second set of records, wherein the grouping is based on the one or more first characteristics and the one or more second characteristics; performing, by the processing device and on the first set of records, a first matching process based on at least one first filtering threshold, the at least one first filtering threshold being determined based on metadata extracted from at least one record included in the first set of records, and the first matching process comprising: a first filtering operation followed by a second filtering operation, the first filtering operation including: comparing the first input biometric sample to a first reference biometric sample associated with each record included in the first set of records, and the second filtering operation including: comparing the second input biometric sample to a second reference biometric sample associated with each record included in the first set of records; performing, by the processing device and on the second set of records, a second matching process based on at least one second filtering threshold, the at least one second filtering threshold being determined based on metadata extracted from at least one record included in the second set of records, and the second matching process comprising: a third filtering operation followed by a fourth filtering operation, the third filtering operation including: comparing the first input biometric sample to a third reference biometric sample associated with each record included in the second set of records, and the fourth filtering operation including: comparing the second input biometric sample to a fourth reference biometric sample associated with each record included in the second set of records; and identifying, by the processing device, a biometric record associated with the individual based on a result of the first matching process and a result of the second matching process.
