Abstract
A message can be encoded in an image file by mapping at least one bit of the message onto each sub-unit of the image file, and adjusting a distinguishable characteristic of each sub-unit according to the corresponding bit to produce a modified image file. The message can be decoded from the message file by comparing each sub-unit of the modified image file with a corresponding sub-unit of the original image file, and identifying at least one bit of the message based on each comparison.
