Information hiding has importance in information security. Generally, information hiding is used to protect, authenticate data or for secret communication such as military secret information. It can be achieved in communication protocols, digital multimedia content such as image, text and audio. Currently available information hiding techniques do not pay much attention on stego-object (hidden information in original object) with respect to its original cover (original) object. Both cover and stego-images are drifted in context of edge characteristics of image objects. That is not affordable in some application such as medical domains applications.
