The present disclosure concerns a method of identifying a biometric record of an individual in a database (108), the database comprising at least first and second sets of records, each set comprising at least one record, the method comprising: receiving by a processing device (102) at least first and second input biometric samples of said individual; performing on the records of said first set a first matching process comprising a first filtering operation followed by a second filtering operation, and performing on the records of said second set a second matching process comprising said second filtering operation followed by said first filtering operation, wherein said first filtering operation comprises comparing said first input biometric sample to a first reference biometric sample of each record, and said second filtering operation comprises comparing said second input biometric sample to a second reference biometric sample of each record; and identifying a biometric record of said individual based on results of the first and second matching processes. |

1. A method comprising:
receiving, by a processing device, a first input biometric sample and a second input biometric sample to be matched with a record of a plurality of records; determining, by the processing device, a first characteristic associated with the first input biometric sample and a second characteristic associated with the second input biometric sample; grouping, by the processing device, the plurality of records to form a first set of records and a second set of records based on comparing a parameter relating to at least one reference biometric sample, associated with each record of the plurality of records, with at least one threshold,
the parameter comprising a quality measurement parameter associated with the at least one reference biometric sample associated with each record of the plurality of records,the grouping the plurality of records being after and based on receiving the first input biometric sample and the second input biometric sample, andthe grouping being based on the first characteristic and the second characteristic; performing, by the processing device and on the first set of records, a first matching process based on a first threshold; performing, by the processing device and on the second set of records, a second matching process based on a second threshold; and identifying, by the processing device, the record that matches the first input biometric sample and the second input biometric sample based on a result of the first matching process and a result of the second matching process. |
