Abstract

This paper proposes a counterfeiting attack on an SVD-based ownership watermarking scheme. In the proposed attack, the adversary can claim the rightful ownership of any image by fabricating a bogus "original" image and meaningful logo. To defend against this attack, this paper proposes to generate the watermark from the original image and owner's logo with a one-way function.
