Abstract:
The invention is a method for scanning an image data file to determine the presence of a payload, including the steps of identifying the values of one or more lower-order bits in the bytes of an uncompressed image data file to determine the distribution of values at one or more bit positions, and comparing bit position images to reveal hidden payloads from significant variations in contiguous color blocks in the bit position images not otherwise explainable from the original image.
