“….Riad et al [23] proposed a scheme exploiting the concept of optimal radius as in Poljicakscheme [18] by embedding the watermarking in the magnitude of the Fourier transform and in watermark detection process, the watermarked image is preprocessed and presence of the watermark is detected using correlation between the optimal radius amplitude and watermark.…”

Digital watermarking is a process in which a piece of information is embedded into a digital data. In this article we review the digital watermarking scheme of image which uses DFT to embed the watermark. Digital watermarking using DFT has attracted researchers due to the fact that watermark using DFT are RST invariant compared to other scheme using other transforms such as DCT or DWT. In the presented article, we tried to cover all the aspect of digital watermarking particularly on DFT based scheme. We also gave some terminology used in the digital image watermarking and briefly discuss the attacks involved in digital image watermarking.

“…Although DCT and DWT are very robust to common signal processing attacks such as compression and signal filtering, they are weak to resist geometric distortions [2]. However, DFT has the advantage of being more resistant to geometric attacks [3,4].…”

“…To be rotation invariant, the watermark vector is embedded in the magnitude of the Fourier transform of the original image, as a circle of radius r around the center of the transformed image in the medium frequency domain, translation problems are being naturally handled by Fourier capabilities. Regarding scaling deformations, in [3,4], they proposed to resize the image to its original size before the watermark detection. However, this Fourier method is not robust to scale deformations in case if the size of original image is unknown.…”

“…After the O. Ruanaidh and T. Pun [5] work, the followed proposed method in literature try to avoid to go through all the steps to get an RST invariant domain, which it compromise on the robustness of the method in the first place. Early studies show that considering shape, position and other parameters related to the watermark are improving on the robustness of the method [4,10].…”

Geometric attacks are still challenging issues in image watermarking. In this paper, the robustness of different insertion position and shape of the watermark are evaluated in watermarking scheme based on Fourier-Mellin transform. We propose diagonal, rectangular, and circular insertion of the mark. The robustness of these techniques against geometric deformations such as rotation, scaling and translation (RST) is evaluated. Results show that the circular insertion performs better for translation and scaling attacks, while the diagonal insertion is better for rotations and RST attacks. The last point makes the diagonal insertion to be preferred in industrial applications since the combination of RST attacks often occurs in many applications such as printing the image on a physical support, and scanning it (print-scan attack).
