Application of BPCS steganography to wavelet compressed video

Abstract: This paper presents a steganography method using lossy compressed video which provides a natural way to send a large amount of secret data. The proposed method is based on wavelet compression for video data and bit-plane complexity segmentation (BPCS) steganography. In wavelet-based video compression methods such as 3-D set partitioning in hierarchical trees (SPIHT) algorithm and motion-JPEG2000, wavelet coefficients in discrete wavelet transformed video are quantized i ....etc

INTRODUCTION

Steganography comes from the Greek and literally means, Covered writing. It is one of various data hiding techniques, which aims at transmitting a message on a channel where some other kind of information is already being transmitted. This distinguishes steganography from covert channel techniques, which instead of trying to transmit data between two entities that were unconnected before.
The goal of steganography is to hide messages inside other harmless messages in a way that does not allow any enemy to even detect ....etc

Steganography is the art and science of hiding information in ways that prevent its detection. Though steganography is an ancient craft, the onset of computer technology has given it new life. Computer-based steganographic techniques introduce changes to digital covers to embed information foreign to the native covers.Digital steganography involves the hiding of data inside a sound or image file.Steganography works by replacing bits of useless or unused data in regular computer files such as graphics, sound, text, HTML, or even floppy disks wit ....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

Definition
Steganography includes a vast array of techniques for hiding messages in a variety of media. Among these methods are invisible inks, microdots, digital signatures, covert channels and spread-spectrum communications. Today, thanks to modern technology, steganography is used on text, images, sound, signals, and more. The advantage of steganography is that it can be used to secretly transmit messages without the fact of the transmission being discovered. Often, using encryption might identify the sender or receiver as somebody with som ....etc

In this paper, we aim to present a general introduction to steganography or data-hiding as it is sometimes just known. We then turn to data-hiding in images. When examining these data-hiding techniques, we bear in mind Benderâ„¢s specifications, such as degradation of the cover data must be kept to a minimum, and the hidden data must be made as immune as possible to possible attack from manipulation of the cover data.

Steganography in images has truly come of age with the invention of fast, powerful computers. Software is readily availab ....etc

Steganography ,from the Greek, means covered or secret writing, and is a long-practiced form of hiding information. Although related to cryptography, they are not the same. Steganography's intent is to hide the existence of the message, while cryptography scrambles a message so that it cannot be understood.

The word Steganography literally means ?covered writing? as derived from Greek. It encompasses all methods of secret communication that conceal the very existence of the message.

Digital technology gives us new ways to apply Steganographic techniques including one of the most intriguing that of hiding information in the digital images. A popular method is the LSB encoding, so encoding and detection of LSB Steganography is discussed in detail. Steganography goes well beyond simply embedding text in an image.

It also pertains to other media ....etc
