Abstract
Watermarking schemes allow a cover image to be embedded with a watermark image, for diverse applications including proof of ownership or for image hiding. In this paper, we present analysis on the improved SVD-based watermarking scheme proposed by Mohammad et al. The scheme is an improved version of the scheme proposed by Liu and Tan and is claimed to be able to solve the problem of false-positive detection in Liu and Tan scheme. We show how the designers’ security claims, related to robustness and proof of ownership application can be invalidated. We also demonstrate a limitation in Mohammad et al. scheme which degrades the whole watermarked image.
