ABSTRACT
Cryptography techniques aim to achieve security in communications by enciphering data. Unlike cryptography, the term Steganography refers to a set of techniques designed to provide covert communication between partners by embedding additional information into an unsuspicious communication. As a field of Steganography, the purpose of digital image watermarking (DIW) is to embed additional information into an image. This information can be later on used for copyright protection, authentication or security control purposes. In order to ....etc

Design and Implementation of a Hardware Divider in Finite Field


INTRODUCTION
Division in finite fields is an important arithmetic
operation that is widely used in channel coding,
cryptography, error correction and code construction
applications. An algorithm that is suitable for hardware
implementation should require few clock cycles and
simple arithmetic operations. One such algorithm has been
proposed for modular division and its inverse in GF(p) is
called the Unified Mod ....etc

Abstract

In recent years, several commercial system-on-chip solutions for MP3 decoding have been developed. They are usually built around a specialised RISC processor with an instruction set suitable for MPEG audio decoding. The purpose of this project is to evaluate and implement the different parts of the MP3 decoding without using a processor core. Instead, small hardware accelerators are implemented for each stage in the decoding chain. Using specialised logic could lower the power consumption that is of most importance in handhel ....etc

Digital Watermarking is a data hiding technique where an information or message is hidden inside a signal transparent to the user. This method is used for copyright protection of digital media. Watermarking differs from encryption in a way that in the former case a general user is allowed to access, view and interpret the signal but cannot claim the ownership of the content, whereas in case of encryption the very access to the signal itself is denied. Watermarking is thus more popular than encryption where the content generator wants the genera ....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
