The IRIS OCR data file is a proprietary format developed by I.R.I.S. for use within its optical character recognition software ecosystem. It functions as a storage medium for character recognition patterns and training data utilized by applications like Readiris to enhance text processing results. As a legacy format primarily containing static structural information, it presents a low security risk and has largely been superseded by modern data standards in current software releases.
