Abstract:
In this paper a technique has been proposed that
enhances the security level by concealing an image inside
another. The method uses Fourier transform with random phase
masks to make it imperceptible by obscuring the secret image. It
further makes use of scrambling to enhance the integrity of the
image. Computer simulations have been carried out in order to
prove the results obtained. Furthermore, peak Signal to noise
ratio along with the effects of occlusion have also been assessed.
The proposed scheme has been subjected to various attacks for
steganalysis and the corresponding values of Correlation
coefficients, Standard Deviation error and mean error are
contemplated.
