ABSTRACT:
Barcode data communication methods, barcode embedding methods, and barcode systems are described. According to one embodiment, a barcode data communication method includes accessing a composite image comprising a disguised barcode image incapable of being directly read from a base image by a barcode reader, extracting data corresponding to the barcode image from the composite image, modifying the data to provide the barcode image in a state wherein the barcode image may be directly read by a barcode reader, and reading the barcode image using the barcode reader after the modifying.
