Definition of Steganography
What is Steganography?
The art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message; this is in contrast to cryptography, where the existence of the message is clear, but the meaning is obscured.

An Analysis of Terrorist Groups- Potential Use of Electronic Steganography
This paper provides an overview of steganography, its historical use during times of war, and how modern day electronic steganography can be accomplished. An overview is provided of current techniques to detect steganography on the Internet, which have so far failed to uncover any evidence of steganography on the Internet, and possible future avenues of research in detecting online steganography using techniques similar to the Federal Bureau of Investigation's Carnivore system. The paper concludes with examples of the dangers of unsubstantiated steganography claims and privacy considerations in detecting online electronic steganography.

Steganography and Steganalysis: An Overview
In order to understand steganalysis it is essential to have an understanding of steganography (stego), the techniques used to hide information. What is steganalysis? Although my 11 year old daughter insists that steganalysis is the study of a two ton, thirty foot long dinosaur with a brain the size of a walnut, a more modern definition would include the discovery and destruction of hidden information.

Steganography: Past, Present, Future
Steganography (a rough Greek translation of the term Steganography is secret writing) has been used in various forms for 2500 years. It has found use in variously in military, diplomatic, personal and intellectual property applications. Briefly stated, steganography is the term applied to any number of processes that will hide a message within an object, where the hidden message will not be apparent to an observer. This paper will explore steganography from its earliest instances through potential future application.

Hiding in Plain View: Could Steganography be a Terrorist Tool?
The events of September 11, 2001 catapulted awareness of terrorism to the forefront of every mind in every civilized culture in the world. They have also raised interest in the ways that terrorists may have communicated and planed these events. Earlier this year, in a USA Today article it was suggested that terror groups may be using the Internet to pass information using techniques including e-mail, chat rooms, bulletin boards and other web sites1. There is also much speculation that these groups may be using technologies like encryption and steganography to help hid their communications.

MP3Stego: Hiding Text in MP3 Files
With the widespread popularity of the MP3 file format and its ubiquitous presence on storage media and the Internet, it was only a matter of time before it joined ranks alongside other steganographic mediums. Johnson defines steganography as "the art of passing information in a manner that the very existence of the message is unknown." Unlike cryptography, which is easily detected (but hopefully difficult to decipher), steganography is an attempt to conceal the very presence of the hidden message. When the two techniques are combined, as they are in MP3Stego, they present a formidable challenge.

Steganography Revealed
Over the past couple of years, steganography has been the source of a lot of discussion, particularly as it was suspected that terrorists connected with the September 11 attacks might have used it for covert communications. While no such connection has been proven, the concern points out the effectiveness of steganography as a means of obscuring data. Indeed, along with encryption, steganography is one of the fundamental ways by which data can be kept confidential. This article will offer a brief introductory discussion of steganography: what it is, how it can be used, and the true implications it can have on information security.

A Detailed look at Steganographic Techniques and their use in an Open-Systems Environment
This paper's focus is on a relatively new field of study in Information Technology known as Steganography. This paper will take an in-depth look at this technology by introducing the reader to various concepts of Steganography, a brief history of Steganography and a look at some of the Steganographic techniques available today. The paper will close by looking at how we can use Steganography in an open-systems environment such as the Internet, as well as some of the tools and resources available to help us accomplish this.

Steganography: Why it Matters in a "Post 911" World
Cryptography attempts to conceal messages by various translation methods that create new, unrecognizable messages. Even though this new, encoded message may be unintelligible to an observer it still remains in plain view. By contrast, the main purpose of steganography or "stego" as it is often called is to hide even the occurrence of messages. While the underlying concepts of steganography have been around for thousands of years, it wasn't until the mid 90s that the concepts evolved into software capable of being run on standard PCs. Trying to keep up with developments in steganography is steganalysis, the science of discovering hidden messages. Today, messages can be hidden in a variety of audio and video files using increasingly sophisticated tools that incorporate both steganography and cryptography. The aptly named "OutGuess", a modern stego tool available from the Internet already makes the claim to be able to defeat steganalytical tools that use statistical analysis.

An Encrypto - Stego Technique Based Secure Data Transmission System
This paper proposed a system that combines the effect of these two methods to enhance the security of the data. This proposed system encrypts the data with a crypto algorithm and then embeds the encrypted text in an image file. The embedding process is done with help of stego-key, and the detection or reading of embedded information is possible only having this key.
