Abstract: Steganographic techniques are useful to convey hidden information by using various types of typically-transmitted multimedia data as cover for concealed communication. Spread Spectrum Image Steganography (SSIS) is a data-hiding/hidden-communication method that uses digital imagery as a cover signal. This report describes an SSIS prototype system for embedding messages in images and extracting messages from stegoimages. The components, which were written in the Java and C programming languages, were kept modular to provide a workbench for further experimentation. We discuss experiments that were performed with the system, along with possible avenues of future research to improve the SSIS process.
