Steganography is the science of secret message delivery using cover media. The cover carriers can be image, video, sound or text data. A digital image is a flexible medium used to carry a secret message because the slight modification of a cover image is hard to distinguish by human eyes. The proposed method is inspired from Chang method of Secret Reference Matrix. The proposed method has high hiding capacity, better stego-image quality, requires little calculation and is easy to implement.
