Steganography – the art and science of hiding information has received much attention in the recent years. It can also be defined as the study of invisible communication that usually involves communication of secret data in an appropriate carrier, e.g., image, audio, video or TCP/IP header file. Many different carrier file formats can be used, but digital images are the most popular because of ...

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 ...

Steganography is the art and science of concealing information in unremarkable cover media so as not to arouse an eavesdropper’s suspicion. It is an application under information security field. Being classified under information security, steganography will be characterized by having set of measures that rely on strengths and counter measures (attacks) that are driven by weaknesses and vulnera...

Steganography is the science of sending messages hidden in harmless communications over a public channel so that an adversary eavesdropping on the channel cannot even detect the presence of the hidden messages. Several models for steganography have been introduced. Some are private-key settings, and the others are public-key settings. In this paper, we propose a model of public-key steganograph...

Information transmission is increasing with grow of using WEB. So, information security has become very important. Security of data and information is the major task for scientists and political and military people. One of the most secure methods is embedding data (steganography) in different media like text, audio, digital images. This paper presents two experiments in steganography of digital...

This paper will take a brief look at the usage of genetic algorithms in steganography. Steganography media which is subjected is image files. So, some of recent studies that introduce the steganography methods are listed and described in brief. As it is seen, robustness and capacity are two important factors that are considered in almost all steganography methods. Also, different methods use on...

Introduction Steganography is derived from the Greek for covered writing and essentially means " to hide in plain sight ". As defined by Cachin [1] steganography is the art and science of communicating in such a way that the presence of a message cannot be detected. Simple steganographic techniques have been in use for hundreds of years, but with the increasing use of files in an electronic for...

oday the exponential growth in internet users demand secure data communication, for that it is required to send the data in the form of encrypted or hidden form. Many information system security techniques are available. They are classified into three classes as cryptography, steganography and watermarking. This paper presents a review on steganography techniques and their uses and attacks on t...

Steganography is the technique of hiding a private message within a file in such a manner that third party cannot know the existence of matter or the hidden information. The purpose of Steganography is to create secrete communication between the sender and the receiver by replacing the least significant bits (LSB)of the cover image with the data bits. And in this paper we have shown that how im...
