Steganography is a branch of information hiding.It allows the people to communicate secretly.Steganography word is classified into two parts: Steganos which means "secret or covered" (where you want to hide the secret messages) and the graphien which means "writing".It aims to embed secret data into a digital cover media, such as digital audio, image, video, etc., without being suspicious looking.In This paper a new image steganography method that hides the secret message inside the cover image using zero order hold (ZOH) is considered.The main goal of this method is to hide a secret message in the pixels of the cover image in such a way that the human eyes are not able to differentiate between the original and the stego-image.
