1. A computer-implemented method of restricting access to images in a financial document archive, where each image comprises a magnetic ink character recognition (MICR) codeline, the method comprising: interrogating a portion of an image comprising an entire MICR codeline with a data matching algorithm; determining whether a confidence score, expressing a likelihood that the portion of the image matches associated stored MICR data, is above a pre-set limit, wherein the pre-set limit is below one-hundred percent; designating the image as not defective and retrievable by customers from the financial document archive if the confidence score is above the pre-set limit; determining whether the confidence score is above a pre-set threshold; designating the image for display to an operator if the confidence score is below the pre-set limit and above the pre-set threshold; and automatically designating the image as unretrievable by customers from the financial document archive when the confidence score is below the pre-set threshold.
