A constructive and unifying framework for zero-bit watermarking [PDF]
, 2006 In the watermark detection scenario, also known as zero-bit watermarking, a watermark, carrying no hidden message, is inserted in content. The watermark detector checks for the presence of this particular weak signal in content. The article looks at this

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.
