Improved Performance of Secure Data Hiding Algorithm Using Non Blind Steganography Technique

Abhishek Sharma, Vijay Sharma

Abstract


In this paper, a method has been proposed using which a large size secret image (containing hidden encrypted message) can be hidden into small size of cover image securely. The main aim here is the absolute invisibility of the large size secret image. The proposed method does not require the sender to send the cover image to the receiver for obtaining the secret image.
