Abstract


With the increase in the availability of digital data such as multimedia services on the Internet, there is a pressing need to manage and protect the illegal duplications a, solution to this problem, a digital watermark technology is now drawing the attentions a new method of protecting copyrights for digital data. In this paper, we present two methods of digital watermark for image signals based on the wavelet transform. We classify wavelet coefficients as insignificant or significant by using zero tree which is defined in the e ....etc

ABSTRACT

Digital watermarking is an extension of steganography, is a promising solution for content copyright protection in the global network. It imposes extra robustness on embedded information. Digital watermarking is the science of embedding copyright information in the original files. The information embedded is called watermarks.

Digital watermarking doesnâ„¢t leave a noticeable mark on the content and donâ„¢t affect its appreciation. These are imperceptible and detected only by proper authorities. Digita ....etc

INTRODUCTION
Project Name: Mat Lab Based water marking

In this project our main aim to add a watermark in image. This project is useful for sites like SANTA BANTA.COM specially they have images to show on site, the user has to download images after viewing it on site, If there is no watermark than user will get image without paying to service provider, so to avoid this provider will add a watermark on their image and only than upload it for demo purposes. It is also helpful in some websites where some products images ....etc

ABSTRACT
Digital watermarking is a technique used for preventing illegal copying and tampering of data. It is similar to the paper watermarking. It is mainly used for two purposes: authentication of data and copyrighting. Using copyrighting we can trace illegal copies of digital data and certify original owners. Also in case of dispute over a data the watermark can be used to prove the ownership. In watermarking the original data is superimposed with a signal containing the copyrighting information. This signal is not per ....etc

INTRODUCTION
EXISTING SYSTEM
Digital Watermark is an invisible mark inserted into the digital multimedia data so that it can be detected in the later stage of evidence of rightful ownership. A great deal of research efforts has been focused on digital watermark in recent years. The techniques proposed so far can be divided into two main groups of according to the embedding domain of the container imag
1) Spatial Domain Approach:
One group is SPATIAL domain approach . ....etc

Introduction
The rapid expansion of the Internet in the past years has rapidly increased the
availability of digital data such as audio, images and videos to the public. As we have
witnessed in the past few months, the problem of protecting multimedia information
becomes more and more important and a lot of copyright owners are concerned about
protecting any illegal duplication of their data or work. Some serious work needs to
be done in order to maintain the availability of multimedia information but, in the
meantime, the indust ....etc

ABSTRACT
Automatic video surveillance (AVS) systems are used for continuous and effective monitoring of dangerous and remote sites. Video data acquired by the automatic video surveillance system can be recorded and presented as a proof in front of court law. But digital video data lacks legal validity due to the ease to manipulate them without leaving any trace of modification. Image authentication is the process of giving a legal validity to the video data. By authentication technique content tampering can b ....etc

DIGITAL IMAGE TRACING BY SEQUENTIAL MULTIPLE WATERMARKING
Abstract
The possibility of adding several watermarks to the same image would enable many interesting applications such as multimedia document tracing, data usage monitoring, and multiple property management. In this paper, we present a novel watermarking scheme, which allows inserting and reliably detecting multiple watermarks sequentially embedded into a digital image. The proposed method, based on elementary linear algebra, is asymmetric, secure under pr ....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
