Title: Digital Hologram Authentication Using
a Hadamard-Based Reversible Fragile
Watermarking Algorithm
Abstract—This paper presents a novel reversible fragile watermarking algorithm
for hologram authentication. In the algorithm, the watermark is embedded in the
transform domain. The marked hologram is then stored in the spatial domain with
finite resolution level. The resolution level is allowed to be pre-specified for
attaining different degrees of transparency. The algorithm is based on Hadamard
transform for both watermark embedding and extraction. The Hadamard transform
and its inverse can be operated by simple addition, subtraction and shift operations.
Due to the simplicity of the transform, a sufficient condition on the resolution level
of marked holograms is derived for guaranteeing the reversibility of watermarking.
In addition, from the condition, it is also observed that the hiding capacity for
reversible watermarking increases with the resolution level. The proposed
algorithm therefore provides high flexibility for reversible watermarking allowing
transparency and hiding capacity to be varied by selecting different resolution
levels. Moreover, a novel scheme is presented for supporting self-containedness
for 3D object reconstruction without requiring the delivery of additional files
consisting of parameters for diffraction computation. Because of its low
degradation in transparency, the algorithm is also able to operate in conjunction
with the existing spatial domain based reversible algorithms to further enhance the
hiding capacity while maintaining high visual transparency.
