ABSTRACT
Cryptography techniques aim to achieve security in communications by enciphering data. Unlike cryptography, the term Steganography refers to a set of techniques designed to provide covert communication between partners by embedding additional information into an unsuspicious communication. As a field of Steganography, the purpose of digital image watermarking (DIW) is to embed additional information into an image. This information can be later on used for copyright protection, authentication or security control purposes. In order to ....etc

Introduction
Steganography is derived from the Greek for covered writing and essentially means to hide
in plain sight. As defined by Cachin 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 format new techniques for information hiding have become
possible.
This document will examine some early examples of steganography and the general ....etc

Digital Watermarking

Abstract :

Todayâ„¢s world is digital world. Nowadays, in every field there is enormous
use of digital contents.Information handled on INTERNET and MULTIMEDIA
NETWORK SYSTEM is in digital form.The copying of digital content without
quality loss is not so difficult.Due to this,there are more chances of copying of
such digital information.So,there is great need of prohibiting such illegal
copyright of digital media.Digital watermarking(DWM) is the powerful solution
to this problem.Digital watermarki ....etc

With the rapid growth of Internet and networks technique, multimedia data transforming and sharing is common to many people. Multimedia data is easily copied and modified, so necessity for copyright protection is increasing. It is the imperceptible marking of multimedia data to brand ownership. Digital watermarking has been proposed as technique for copyright protection of multimedia data. Digital watermarking invisibly embeds copyright information into multimedia data. Thus, digital watermarking has been used for copyright protection, finger ....etc
