Abstract
The steganography is the discipline of trouncing data into innocuous media in a manner that reality of the hidden data remains invisible to an antagonist. Varieties of methods have been developed over time in the area of image steganography. Robust steganography technique increases data protection from an adversary even if an attacker clutches the knowledge about the embedding process. Modern information security system combines both cryptography and steganography techniques. This paper proposes an image steganography method, at the initial stage secret image is encrypted using advance encryption standard (AES) and afterwards hide the results of AES into the picture (i.e. cover media or cover image) with the assistance of Haar Discrete Wavelet Transform and alpha blending. These efforts ensure that the proposed data hiding mechanism gives higher imperceptibility and trustworthiness which is the essential requirements of any steganography technique. All practical implementation perform on MATLAB.
