Objective In order to improve the watermark against geometrical attacks, holographic watermark was produced by DCT transform (Cosine Transform) and embedded in the IF region of the host image by DCT technology, in combination with Randon transform technology, the watermark was granted with high resistance to cutting and geometric distortion. Methods Firstly, the imaging characteristics of holographic watermark was introduced according to the FFT (Fast Fourier transformation) and DCT holographic features. Then hologram optical interference was generated by the computer system with reference to the original digital information, and then the holographic image underwent DCT transform, and was embedded into the Y channel of the host image by DCT. Finally, Randon transform algorithm was used to detect the binding inclination angle of the scanned image. Results Experimental results showed that when the embedding intensity was a=0.4 for the embedding of print scan, the PSNR of the watermarked image reached 39.53, and the watermark SSIM reached 0.783. The embedded watermark had strong invisibility, the extracted watermark was clear, the embedding capacity was high, and there was certain level of robustness. Conclusion Therefore, this algorithm could quickly and accurately extract watermark image from the host image which suffered from rotation, filter, noise, cropping, or other geometric distortion attacks.
