Steganography

Home

Welcome to the Poised Solutions, Steganography web site.

This site has been designed to be an entertaining look into the world of digital Steganography. There is a Steganography library you can download, and use straight away, and the site offers a good look into the basics of digital Steganography, allowing you to develop your own ideas about what makes for good Steganography.

The concentration is on mainly image based digital Steganography, though building on the ideas and concepts found here the idea could be extended to audio based digital Steganography, another excellent base for coverData.

Pages

Introduction - a brief look at the history of Steganography, how Steganography differs to and is combined with encryption, and an explanation of digital Steganography terms that are used throughout the site.

Explanation - this page explains in words how image based digital Steganography is achieved. Diagrams and tables show the values as they pass through the different stages of Steganography.

Interactive example - some people find it easier to analyse data when they participate in the data creation. This page is a JavaScript based application that shows each stage in the Steganography process, including decoding.

Source Code - this page shows analysis for a Steganography library, and then goes on to develop the library in stages. The source code is in python, and the end result is a flexible Steganography module.

Steganalysis - Steganography can be detected, especially if the coverData is known along with the StegData. This page shows a basic Steganalysis technique to derive the encoded data using the GIMP (GNU Image Manipulation Program).

Download - Steganography and Steganalysis applications, libraries, and modules that Poised Solutions has decided to share with the public, are available from this page.

Steg Guess - do Steganography images look obvious? This page contains a JavaScript based guessing game to see if you can compare the difference.
