ABSTRACT:
Embodiments of the present invention are directed to a system and method for processing and identifying a first data file, the first data file having set of data points, wherein each data point is defined by an x,y coordinate and has a value corresponding to the lightness or darkness of the data resident at the data point, comprising: dividing the first data file into segments; identifying the coordinates of at least one contrast point for each segment; creating a first set of identifiers for the data file, creating a second set of identifiers for a second data file, comparing at least one identifier of the first data file to the corresponding identifier in the second data file; and assessing whether at least a portion of the second data file matches at least a portion of the first data file.
