The goal of steganography is to hide the fact that a covert communication is present within an innocuous communication, in this work area you have access to the original work. The goal of steganalysis is to detect when a covert communication is occurring, in this work area you don t have access to the original work. Aside of the background research performed to the concept of steganography we have done the following - Prepared the environment to run and test the Digital Invisible Toolkit in a windows 7 laptop - Tested encode, decode, stegAnalysis and benchmark functions by providing a color image as the cover work and a notepad document as the message input. - Reviewed the battlesteg algorithm java code.
