This project will investigate methods for encoding text messages in 
computer image files, a process called steganography.

\section{Introduction}
{\sl Steganography} is a term for processes that hide information within 
some medium.  For example, the microdot images used by spies during the 
Cold War were a kind of steganography.  In recent years, steganography 
with computers has grown in popularity because of the ability to more easily 
place steganographic data within images, audio files, etc.  This project's 
goal is to develop and investigate methods for hiding text messages in 
computer image files.

\section{Background}
The idea of hiding data within computer images is not new.  Multiple programs already exist for this purpose, and some are available for download on the Internet.  These programs, such as JPHIDE\cite{Latham} and GZSteg\cite{Wilson} take images in common file formats like JPEG and modify them slightly to include a user-specified text message.  Each has its limitations, and other programs have been created to detect images that have been processed by the steganography programs\cite{Provos}.
