Abstract

In this paper, we use one fast Fourier algorithm of the Fresnel integral transform (S-FFT) to realize the digital watermarking information of hologram. The most important point is that by the four-step phase shifting method to obtain four holographic images. We can randomly choose a holographic image embedded in the vector image, thus realizing the digital watermarking technology of holographic images, and the remaining three holograms as watermarking information stored as public key in the optical code. For the host image of containing the watermarking information to do the inverse operation of the watermarking embedding process, we can extract the watermarking information hologram. Used the extracted watermarking hologram and others three public holograms we can reconstruct the watermarking image by four-step phase shifting hologram reconstruction. In this paper, the results of experiments are given by using MATLAB simulation software, the results show that under the premise which is almost without affecting the visual quality of the host image, the extracted image with high resolution, and the watermarking algorithm achieves the desired results.
