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

1.INTRODUCTION
This document describes the Software Development LifeCycle (SDLC) for small to medium database application development efforts This chapter presents an overview of the SDLC, alternate lifecycle models, and associated references. The following chapter describes the internal processes that are common across all stages of the SDLC, and the third chapter describes the inputs, outputs, and processes of each stage. Finally, the conclusion describes the four core concepts that form the basis of this SDLC.

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

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
