Application ID: 14925301

Base Claim:
1. An apparatus comprising processing circuitry configured to execute instructions for: receiving a first threshold and a second threshold; receiving a plurality of binary reference samples; processing each reference sample of the plurality of reference samples via operations including: 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 via operations including: 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, the unique identifier being marked as a duplicate of the previously stored fingerprint; and otherwise, if the first matching score for each previously stored fingerprint is less than the first threshold, storing a corresponding reference sample unique identifier to reference sample fingerprint pair in the reference library; receiving a binary query sample; processing the binary query sample via operations including: producing a query sample fingerprint from the binary query sample; scoring the query sample fingerprint with each previously stored fingerprint in the reference library to produce a second matching score; for each previously stored fingerprint for which the second matching score meets or exceeds the second threshold, reporting a corresponding reference sample unique identifier associated with the previously stored fingerprint and the second matching score.

Claim 9:
9. The apparatus of claim 1 , wherein each of the reference samples is a passage of text.
