Abstract :

The main purpose of developing a digital image encryption technique is to satisfy both imperceptibility and robustness requirement. Digital encryption appear as an efficient means of securing multimedia contents such as copyrighting protection and image authentication. The key aspects some encryption and decryption techniques are robustness and tampering proofing. In this paper robustness is improved through combination of discrete wavelet transform and singular value decomposition method. DWT is used for decomposition of image into sub bends which gives linear flexibility of images in terms of scalability, resolution and distortion. By adding SVD along with DWT, peak signal to noise ratio can be improved. Results is analysed by MATLAB.
