Abstract
This paper propose a digital watermarking algorithm for a digital hologram which is the most valuable image content. It is highly necessary to protect the ownership of a digital hologram. This paper introduces a watermarking scheme, a method to protect the ownership of digital holograms using the Fresnel transform domain data as the ones to be watermarked. Experiment results indicated that the proposed scheme was very imperceptible in the digital hologram and in the reconstructed holographic image. Also, they showed quite strong resistance to most of the attacks. we expect that the conclusions of this paper can be the basis for further research on the digital watermarking for digital holograms.
