An Effective Wavelet-Based Watermarking Scheme Using Human Visual System for Protecting Copyrights of Digital Images
Abstract—.
The modern era of information technology facilitates easy duplication, manipulation and distribution of digital data. This has demanded the certainty for effectively safe guarding the rightful ownership of digital images. Copyright protection and content authentication of digital images have emerged as an imperative concern to content owners and distributors. Digital watermarking provided a potential soluti ....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

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

Imperceptible Watermarking Algorithm Using Block LSB Scheme for Color Images
ABSTRACT
It is well known that now a dayâ„¢s more and more people are publishing papers, books, videos and photographs on the internet. The numerous properties of digital media have made copyrights violations easy. The simple replication and transmission as well as file sharing are just some examples. To overcome that the proposed technique is imperceptible watermarking algorithm using spatial domain block LSB scheme for color image authentication. Watermark i ....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

Abstract:
Problem statement: In recent years, as digital media are gaining wider popularity, theirsecurity related issues are becoming greater concern. Method for authenticating and assuring theintegrity of the image is required. Image authentication is possible by embedding a layer of theauthentication signature into the digital image using a digital watermark. In some applications tamperlocalization is also required. Approach: In this study, we proposed a fragile image authenticationsystem with tamper localization in wavelet domain. ....etc

DWT Based Blind Digital Video Watermarking Scheme for
Video Authentication




INTRODUCTION

Video is a three-dimensional array of color pixels. Two
dimensions serve as spatial (horizontal and vertical) directions of
the moving pictures, and one dimension represents the time
domain . Digital video offers a number of advantages over
analog video, including the ease of sharing and storage, no
degradation of data quality when replicated, easy and inexpen ....etc

Fragile Watermarking Scheme for Relational Database


Existing System

Database integrity has long been considered one of the three pillars in the database security arena, together with authentication and authorization (access control).

But the research of database integrity mainly focuses on semantic integrity constraints, which are rules defining the correct states of the database. Traditional approaches use verification information such as message authentic ....etc
