Abstract
Digital watermarking technique emerged as a tool for protecting the multimedia data from copyright infringement. In digital watermarking an imperceptible signal is embedded into the host image, which uniquely identifies the ownership. In the proposed algorithms, DNA sequence is used as a digital watermark, as the DNA sequences are unique and difficult to copy. This paper proposes two algorithms namely content based watermark algorithm using DNA sequence (CBDNA) and user specified watermark algorithm using D ....etc

Image compression is the application of data compression in digital images. Image compression can be lossy or lossless. This document attempts to implement basic JPEG compression using only basic MATLAB functions. In this work, lossy compression techniques have been used, where data loss can not affect the clarity of the image in this area. Image compression solves the problem of reducing the amount of data needed to represent a digital image. It is also used to reduce redundancy which is no more than avoiding duplic ....etc

ROBUST DWT-SVD DOMAIN IMAGE WATERMARKING: EMBEDDING DATA IN ALL FREQUENCIES
Watermarking (data hiding) is the process of embedding data into a multimedia element such as image, audio or video. This embedded data can later be extracted from, or detected in, the multimedia for security purposes. A watermarking algorithm consists of the watermark structure, an embedding algorithm, and an extraction, or detection, algorithm. Watermarks can be embedded in the pixel domain or a transform domain. In multimedia applications, embedded watermarks shou ....etc

Image Watermarking

It s a step against illegal duplication and manipulations.

Embedding information inside a cover message with little or no degradation of cover object.

Properties of watermark:
Perceptually invisible
Extraction should be fairly simple
