Digital Fresnel hologram watermarking [PDF]

2010 9th Euro-American Workshop on Information Optics, 2010
We present a method of digital hologram watermarking using a Fresnel hologram of a real-world 3D object and the fractional Fourier transform. A watermark is encrypted using double random phase fractional Fourier domain encoding technique and then encoded into the digital hologram.
