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

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

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

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.

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

Dear sir
I need system flow diagram for my final year project.My project is about video stegnography. I have to get an video input and that video is split into audio and vedio.and then vedio is split into frames and that frames are selected to hide the message.and the sender have extract the message in the same way using multivariate regression concept. this is the over view of my project can provide the SFD for this project

Ramya ....etc
