New Image Steganography Method using Zero Order Hold Zooming

Abstract

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.
