Abstract

Commonly used watermarking algorithms were analyzed. It was founded that discrete wavelet transform, discrete cosine transform, and singular value decomposition can meet the demand of resisting rotation attacks and double random phase encrypted holographic technology can meet demand of security. Holographic watermark image was embedded into the transform domain. The influences of rotation, scale, translation, median filter, Gaussian noise, salt and pepper noise, and JPEG compression on the quality of extracted watermark image were studied by experiments. The result showed that the holographic digital watermarking technology based on transform domain can resist common geometric attacks, especially rotation attacks, and effective to resist common noise and compression attacks. It was concluded that the watermarking technology is of both robustness and security.
