Abstract
A method of forming a dispersed message for embedding in an image, includes the steps of: providing a random phase carrier; defining a set of ordered bit locations; assigning a polarity to each bit location corresponding to a bit of the message; cyclically shifting the random phase carrier in accordance with each bit location and weighting the cyclically shifted carriers by the polarity of the corresponding bit; and forming a sum of the cyclically shifted weighted carriers to form the dispersed message.
