ABSTRACT
Analysis and control of dynamical systems have been explored since long by various researchers as it is vital to design systems to meet out desired behaviour successfully. Chaotic systems belong to a special class of systems which has drawn tremendous amount of interest because of its applications ....etc

Abstract: Watermarking techniques are primarily used for copyright protection. A simple and robust watermark-like digital authentication scheme is proposed. This work has two major merits. First, the watermark used in the proposed authentication scheme is the same type used in the original image, e.g. grey level images. Second the proposed scheme meets the requirements for watermarking techniques. llegal users cannot perceive and break the watermark signed from the original image. Furthermore, the signed watermark is robust a ....etc

ABSTRACT

Chaos maps and chaotic systems have been proved to be useful and effective for cryptography. In our study, the two-dimensional logistic map with complicated basin structures and attractors are first used for image encryption. The proposed method adopts the classic framework of the permutation-substitution network in cryptography and thus ensures both confusion and diffusion properties for a secure cipher. The proposed method is able to encrypt an intelligible image into a random-like one from the statistical point of view and the hum ....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 inexpensive
copying and the capa ....etc

Imperceptible Watermarking Algorithm Using Block LSB Scheme for Color Images
ABSTRACT
It is well known that now a day 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 is one ....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 authentication codes (MAC) and ....etc

In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. In this communication, we propose a new approach for image encryption based on chaotic logistic maps in order to meet the requirements of the secure image transfer. In the proposed image encryption scheme, an external secret key of 80-bit and two chaotic logistic maps are employed. The initial conditions for the both logistic maps are derived using the external secret key by providing different weig ....etc
