1. A method comprising:

  • receiving, by a processing device, an input biometric sample to be matched with a record of a plurality of records stored in a data structure;

    determining, by the processing device, a characteristic associated with the input biometric sample;

    partitioning, by the processing device and triggered by receiving the input biometric sample, the plurality of records by grouping the plurality of records stored in the data structure to form a first set of records and a second set of records based on a threshold associated with the characteristic;

    performing, by the processing device and on the first set of records, a first matching process that compares the input biometric sample and the first set of records;

    performing, by the processing device and on the second set of records, a second matching process that compares the input biometric sample and the second set of records,the first matching process using a filter with a different threshold than the second matching process;

    identifying, by the processing device, the record that matches the input biometric sample based on a result of the first matching process and a result of the second matching process;

    providing, by the processing device, an identification result that indicates the record that matches the biometric sample was found;

    receiving, by the processing device, another input biometric sample; and

    dynamically re-partitioning, by the processing device, the plurality of records based on receiving the other input biometric sample.
