Double random phase encoding method usinginterleaving algorithm for security consideration

This paper proposed a new watermarking methodbased on double random phase encoding (DRPE). In theconventional DRPE method, two random phase masks (keys) areneeded. Obviating the need of sending large keys through asecure channel, we generated the Fourier mask by interleavingprocess. Having the interleaver key and source image, thewatermark can be reconstructed. Experimental results show thatthe proposed method is robust to noise and attacks.
