Didi Rosiyadi, Heri Prasetyo, Shi Jinn Horng, Akbari Indra Basuki · 2020
The secret sharing based watermarking scheme using the Fractional Fourier Transform (FrFT) and Singular Value Decomposition (SVD) has been proven to yield the outstanding results. This method embeds the singular value matrix into the FrFT transformed sub-bands. The FrFT transformed sub-bands are computed from the Samir Secret Sharing (SSS) scheme. As reported in literature, the aforementioned scheme achieves a good imperceptibility aspect as well as robust against some malicious attacks and geometric distortions. However, it cannot confront the attack presented in this paper. An attacker can simply perform this attack to the FrFT-SVD based on image watermarking scheme to obtain the desired counterfeit watermark image. It demonstrates the vulnerability issue of the FrFT-SVD-based image watermarking scheme.
