1. A computer-implemented method of restricting access to images in a financial document archive, the method comprising: interrogating an image with a data matching algorithm; determining whether a confidence score expressing a likelihood that the image matches associated, stored magnetic ink character recognition (MICR) data is above a pre-set limit; designating the image for further processing if the confidence score is above the pre-set limit; determining whether a confidence score expressing a likelihood that the image matches associated, stored magnetic ink character recognition (MICR) data 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 designating the image as unretrievable by customers from the financial document archive when the confidence score is below the pre-set threshold.
