摘要

A fragile watermarking algorithm for hologram authentication is presented in this paper. In the proposed algorithm, the watermark is embedded in the discrete cosine transform (DCT) domain of a hologram. The watermarked hologram is stored in spatial domain with finite precision level. By enhancing the precision for storing the watermarked hologram pixels, the distortion produced by the proposed watermarking scheme can be lowered. While providing high perceptual transparency, the proposed algorithm also attains high performance detection to delivery errors and malicious tampering. Experimental results reveal that the proposed algorithm can be used as an effective filter for blocking polluted or tampered holograms from 3D magnitude and/or phase reconstruction.
