To maintain the privacy and certainty of pictures is a spirited area of research, with two totally different approaches being followed, the first approach is encrypting the pictures through encoding algorithms using keys and the secondary approach is hiding the data using data hiding algorithms to take care of the pictures secrecy. A content owner encrypts the original image by using an encoding key and an information-hider can embed further data into the encrypted image employing a data-hiding key although they doesn't recognize the original content.
