WHAT IS STEGANOGRAPHY ?
Steganography is technique that facilitates hiding of message that is to be kept secret inside other message .
This result in the concealment of the secret message itself ? Historically The sender uses method such as invisible ink . which is used write to secret message on the paper .
But "Steganography" hide secret message within graphics image.
For instance ,suppose that we have secret message to send .We can take another image file and we can replace the last two rightmost bits of each byte of that image with(next) two bits of our secret message.
The resulting image could not look too different, and yet carry a secret message inside.
The receiver would perform the opposite tricks ;it would read the bits of each byte of the image file
and reconstruct the secret message
Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol.
