Method and Apparatus for Spread Spectrum Image Steganography (Jointly owned with the Army)

Detailed Technology Description: The Spread Spectrum Image Steganography (SSIS) of thepresent invention is a data hiding/secret communication steganographic systemwhich uses digital imagery as a cover signal. SSIS provides the ability to hidea significant quantity of information bits within digital images while avoidingdetection by an observer. The message is recovered with low error probabilitydue the use of error control coding. SSIS payload is, at a minimum, an order ofmagnitude greater than of existing watermarking methods. Furthermore, theoriginal image is not needed to extract the hidden information. The proposedrecipient need only possess a key in order to reveal the secret message. Thevery existence of the hidden information is virtually undetectable by human orcomputer analysis. Finally, SSIS provides resiliency to transmission noise,like that found in a wireless environment and low levels of compression.
