Review on spatial domain image steganography techniques

Abstract

Steganography techniques leads main role in embedding process of secret information into cover information in order to provide good security. These techniques are very essential, when sending the confidential information from one place to another place in the field of defense and medical. Hence, it is a challenging and important task to hide the secret information in to cover information. This review provides classification of steganography techniques, existing and proposed techniques with advantages and disadvantages. As per observations of existing methods, much amount of information hides using spatial domain techniques than transform domain techniques. This review mainly focuses on the spatial domain image steganography techniques.
