title: Steganography in Digital Media: Principles, Algorithms, and Applications
author:  Jessica Fridrich 
description: "...the book is excellent for teaching the subject of information hiding or security related courses. It enhances the landscape of textbooks on the subject. I am convinced that it will grip the reader as it touches on the most important aspects of steganography and steganalysis."<br /><br /> - Wojciech Mazurczyk, IEEE Communications Magazine<br /><br />
