Image Steganography Using the Fusion of Quantum Computation and Wavelet Transformation

In the advancement of information technology the role of security of information is very significant. Many organization including research and educational institute, IT companies exploring the area of quantum computation due to which the field is advancing very quickly. The mechanism of quantum computer provides greater security for quantum data. So in this research we present a new high security steganography system using hybridization of quantum computation and wavelet transformation. The proposed algorithm provides dual security for the embedded data as we transform the normal signal of the high frequency information of wavelet transformation into quantum signal before embedding the secret information. The message extraction process depends on the corresponding coefficient value of low frequency information which acts as a pseudo random key. To assess the accomplishment of our proposed algorithm we have used three parameters MSE, PSNR and RS for different image formats. All these metrics showed that there is very less distortion of the original image.
