Abstract
Digital watermark is used to prove the rightful ownership or protect a customer's right of using the medium. Liu et al. proposed a SVD-based watermarking scheme, but their method has a serious defect; for un-watermarked images it still incorrectly extracts out the watermark. In this paper, we propose an improved SVD-based watermarking method to resolve this defect. We will show our method is successful in resolving rightful ownership of watermarked image with good accuracy, good robustness and good imperceptibility.
