What Is Steganography?

Image Steganography: In today’s digital world secret messages get embedded in to the digital image which is called as Image Steganography where cover object used is Image . Because of the limited power of the Human vision system this method is most commonly used [5]. According to Duncan Sellars [4], image can be explains as “ To a computer , an image is an array of numbers that represents light intensities at various points or pixels. These pixels make up the images raster data. Image steganography

IMAGE STEGANOGRAPHY REVIEW 1. INTRODUCTION With the rapid development of computer technologies and internet, one can get any information through internet very easily. To transfer or convey a message from one point to another is also very convenient in today’s era. People who have internet and computer can get any type of information related to any field without any difficulty [1]. While transferring or communicating on internet safety and security remains an issue. Steganography schemes are

1. Introduction 1.1. What is steganography: Steganography is derived from the greek words stego which is known as cover and grafia which is known as writing which is combinedly known as “covered writing”. It is also defined as the art and science of communication in such a way that it hides the existence of the communication. In contrast to cryptography, steganography hides message inside other harmless message in such a way that the enemy connect detect that there is a hidden message inside the

Anonymity *Figure 1: Methods of Information Hiding For the purpose of this paper, I will be focusing on Steganography, which I believe is the most efficient part of steganography. Unlike other Information hiding methods where the encryption is usually detectable, steganography takes it further by hiding the message within mediums like images, main it almost impossible to detect. The purpose of this paper is to explain Steganography, how

Steganography has been around since 1980’s. Various tools and software’s are available for Steganography as well as Steganalysis. The most common form of steganography is on digital images. For digital images there exist many steganographic techniques and furthermore there exist a lot of approaches to detect steganography in digital images. In this paper we will be looking at many tools comprising from various digital domains but we fund that almost all of the tools had support for image files. With

1. Introduction The aim of this report is to investigate where and how anti-forensic tools work as well as looking at the challenges forensic investigators are faced when such tools are used. After anti-forensic tools are used certain artefacts will be left behind, this report will also cover the procedures and difficulties when trying to uncover these artefacts as well as the tools used to find them. Anti-Forensic (AF) techniques are the actions which are aimed to prevent forensic investigators

Steganography (pronounced STEHG-uh-NAH-gruhf-ee, from Greek steganos, or "covered," and graphie, or "writing") is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography takes cryptography a step further by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning data will fail to know it contains encrypted data (Neijts and Semilof, 2007). The need to keep sensitive information out of the hands of certain

The application makes a stego picture in which the individual information is implanted and is ensured with a secret word which is very secured. The fundamental goal

access to the system?”. Biometric system answers all these questions by authenticating the users. Every second information is shared and transferred between people and it is important to make sure that what is sent by sender is what received by the receiver thus raising the demand of security. Steganography is one of the techniques used for securing the data. The secret message is hidden inside a cover media like audio, video or image with the help of a secret key. Biometric templates can also be secured

Abstract- Steganography means secret communication. It can also be defined as the study of invisible communication that is used to hide the existence of the communicated data in such a way that it remains confidential. In steganography, secret data can be communicated in an appropriate multimedia carrier such as image, audio and video files. Steganography can be classified into two types - Adaptive steganography and Non-adaptive steganography. Each has its strengths and weaknesses. In this paper
