INFORMATION HIDING USING STEGANOGRAPHY
[attachment=16433]
Introduction
One of the reasons that intruders can be successful is that most of the information they acquire from a system is in a form that they can read and comprehend. Intruders may reveal the information to others, modify it to misrepresent an individual or organization, or use it to launch an attack. One solution to this problem is, through the use of steganography.
Background of the Problem
Steganography become more important as more people join the cyberspace revolution. Steganography is the art of concealing information in ways that prevent the detection of hidden messages. Steganography include an array of secret communication methods that hide the message from being seen or discovered.
Scope
The scope of the project as follow:
(i) Implementation of steganographic tools for hiding information includes text and image files.
(ii) Three different approaches being explored which are least significant bit, masking and filtering and algorithms and transformation.
Steganography vs. Cryptography
Basically, the purpose of cryptography and steganography is to provide secret communication. However, steganography is not the same as cryptography. Cryptography hides the contents of a secret message from a malicious people, whereas steganography even conceals the existence of the message.
