Abstract
Presented are systems and methods for creating a set of signatures including acquiring a data set and converting the data set into a plurality of data matrices. The system determines a prime number and determines a plurality of primitive roots to the prime number. The system calculates a template matrix using a first and second primitive root, of the plurality of primitive roots, and selects a data matrix property of interest. The system calculates a first hash function for each of the data matrices to create a first signature for each data matrix such that a main set of signatures is formed, wherein the first hash function is calculated using said property of interest, the prime number, and the template matrix. The system generates a main set of signatures based on the first hash functions, wherein the main set of signatures comprises a first signature for each data matrix.
