    Abstract

    In this paper, we propose an optical image watermarking scheme using the fractional Fourier transform. A two-dimensional watermark is encrypted using a double random fractional order Fourier domain encoding technique. The encrypted image is watermarked into a three-dimensional intensity image reconstructed from a real in-line digital hologram. The watermark is recovered by applying the corresponding correct fractional orders and random phase masks. Results of computer simulation have been presented in support of the proposed watermarking scheme.
