A Novel Low Distortion Image Steganography for Executable Files

Steganography is the process of embedding a ―secret‖ digital data in another cover data. Not like general digital watermarking applications, steganography tries to form secret communication between the sender and receiver and thus causes the requirement of hiding the presence of the embedded message. This paper proposes a new steganography method for hiding executable files where palette images are considered as cover images. In this paper, a new algorithm has been proposed for hiding executable files and the experiment results show that the proposed technique provides a high load steganography arrangement in the pixel domain. Also the proposed approach provides a new idea by which the secret bit assignment with the embedding regions of the cover image. Since the image is divided into several regions and the embedding region is identified as it will generate lower distortion rate, this approach could be considered very secure one against steganalytic attacks.
