A High End Capacity in Digital Image Steganography: Empowering Security by Mottling through Morphing
Sanjay Bajpai, Kanak Saxena · 2014
One of the many techniques to provide security during data communication is digital image steganography. Embedding capacity and distortion are the two main factors that play a vital role while hiding a message in an image. A balance has to be maintained between the two so that neither does affect the other. Proposed paper discusses the techniques which comprises of two phases that leads to formulation of very secure platform with high embedding capacity. First phase mottles the arbitrary image by morphing through two parameters - text or/and image to obtain the cover image which depends upon the features of the chosen image. Second phase embeds the text message of sufficient large length incorporating multi-keys and compound operators in the algorithm to cater robust security. A bunch of images having almost the same texture are transmitted over the network to make the extraction process further complex. Our experimental results prove the horizon touching embedding capacity with extra security layer.
