Efficient & Secure Data Hiding Using Secret Reference Matrix
Laxman Tawade · International Journal of Network Security & Its Applications · 2012
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 data is hidden in 8 bit gray scale image using 256 X 256 matrix which is constructed by using 4 x 4 table with unrepeated digits from 0~15.The proposed method has high hiding capacity, better stego-image quality, requires little calculation and is easy to implement. .
