Statistical steganalysis.

Steganography is the art and science of hiding the presence of communication by embedding secret content into cover documents. While most steganographic embedding methods in use today are invisible to the observer's senses, mathematical analysis may reveal statistical discrepancies in the stego medium. This dissertation examines the problem of detecting steganographic; content and introduces novel methods to solve the detection problem. To understand how to detect hidden content, an understanding of how to prevent detection is necessary, so I also examine methods for preventing detection by steganalysis.
