A Survey of Spatial Domain Techniques in Image Steganography

Abstract

This paper presents the most techniques of spatial domain that used in image steganography where it is used to hide confidential message under a cover image. Steganography is a much better way to convey a secret message compared to cryptography. This is because cryptography is outlawed while steganography can avoid such policies to pass message covertly. Steganography is one of the most common techniques of securing information, which insists on concealing the clandestine data within the cover image in a way that nobody suspects to its existence. The challenge of steganography techniques is to make a reasonable balance between the file and the size of data that can be exchanged. Furthermore, the strength of the strategy and the security of the mysterious data are the fact that can't be hidden.
