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

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

Web database publishing is a new way to publish information electronically. A typical Web database publishing system has a Web browser as its user interface, a database server as its information store, and a Web server connecting the two. The basic idea of this project is to use JDBC to search databases directly from an Internet Web browser. The database is kept on an NT server. JDBC is used to interact with Web pages. This project uses a simple interface to help the administrator update the database on the Web server. Some security issues are ....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

Abstract— In this paper, our research objective is to develop a
database virtualization technique so that data analysts or other
users who apply data mining methods to their jobs can use all
ubiquitous databases in the Internet as if they were recognized as a
single database, thereby helping to reduce their workloads such as
data collection from the Internet databases and data cleansing
works. In this study, firstly we examine XML scheme advantages
and propose a database virtualization method by which such

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

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
