In a nutshell, the main motive of steganography is to hide the intended information within any image/audio/video that doesnt appear to be secret just by looking at it.The idea behind image-based Steganography is very simple. but we can encode a single bit of information ie is there a lot of this color in Why don't we use the 7805 for car phone chargers? Early Evidence of Steganography 7.
