Abstract
A message is embedded into a digital image by forming a digitized version of the message and convolving the digitized message with a random phase carrier to form a scrambled message. The scrambled message is then combined with the digital image to form an embedded message image that is near impossible to extract without knowledge of the formation of the random phase carrier.
