Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows the existence of the message; This is in contrast to cryptography, where the existence of the message is clear, but the meaning is obscured. The name comes from Steganographia by Johannes Trithemius: a treatise on cryptography and steganography disguised as a book on black magic, and is Greek for "occult writing."
Steganography in Java
Steganography is the art and science of writing hidden messages in such a way that no one, other than the sender and recipient, suspects the existence of the message, a form of security through darkness. The image in which the message is to be hidden is known as the operator image and the message or file to hide is known as the payload. Each bit of the payload is hidden in the least significant bit of red, green and blue for each pixel. That means we can hide 3 bits of payload per pixel.
