Objective To find a digital watermarking algorithm against geometric attacks and of security. Methods By analyzing commonly used algorithms, it was found that the algorithm based on Fourier-Mellin transform was able to meet the demands of resisting geometric attacks and that the double random phase encrypted holographic technology was able to meet the demands of security. Using the method of embedding holographic watermark image into Fourier-Mellin domain, the influences of rotation, scale, translation, median filter, Gaussian noise, salt and pepper noise, JPEG compression, print-scan and print -shooting on the quality of imaging were investigated by experiments. Results The results showed that the holographic digital watermarking technology based on Fourier-Mellin transform could resist geometric attacks, especially the images taken by a phone or scanner and image attacks by combinations of geometric attacks such as rotation scale and translation. Conclusion The holographic digital watermarking technology based on Fourier-Mellin transform is of both robustness and security.
