Abstract
A method for identifying similarity between query samples and stored samples in an efficiently maintained reference library may include receiving a first threshold and a second threshold, receiving a plurality of binary reference samples, and processing each reference sample of the plurality of reference samples. The processing may include operations of assigning each reference sample a respective unique identifier, producing a reference sample fingerprint for each reference sample, and registering each respective unique identifier to reference sample fingerprint pair in a reference library. The registering may include scoring the reference sample fingerprint with each previously stored fingerprint in the reference library to produce a first matching score, if the first matching score meets or exceeds the first threshold for a previously stored fingerprint, determining the reference sample fingerprint to be a duplicate of the previously stored fingerprint and recording only a unique identifier associated with the reference sample fingerprint in the reference library where the unique identifier is marked as a duplicate of the previously stored fingerprint, and otherwise, if the firs…
