Patent ID: 8023718

Claim:
A method for linking front and rear images in a document processing system, the document processing system including an imaging device and a magnetic ink character recognition (MICR) reader, the method comprising: capturing a first image and a first waveform for a magnetic ink character sting from a document, the first image and the first waveform corresponding to the front side of the document; applying a forward recognition algorithm to compare the first waveform to a set of known character profiles to produce a first code line; capturing a second image and a second waveform for the magnetic ink character string from the document, the second image and the second waveform corresponding to the rear side of the document; applying a reverse recognition algorithm to compare the second waveform to the set of known character profiles to produce a second code line, wherein the reverse recognition algorithm considers the second waveform as resulting from the document being read from the rear side of the document when comparing the second waveform to the set of known character profiles; and comparing the first code line to the second code line to verify that the first image and the second image are captured from the same document.
