ABSTRACT:: Techniques and applications for information hiding have
become increasingly more sophisticated and widespread. With
high-resolution digital images as carriers, detecting the presence of
hidden messages has also become considerably more difficult. It is
sometimes possible, nevertheless, to detect (but not necessarily
decipher) the presence of embedded messages. The basic approach taken
here works by finding predictable higher-order statistics of
``natural'' images within a multi-scale decomposition, and then
showing that embedded messages alter these statistics.
