A Novel Watermarking Method with Image Signature

Abstract

In this paper, we propose a novel invisible watermarking method with image signature, which can resist not only common image attacks but also copy attack. The image signature algorithm referred is based on Image Independent Block Feature (IIBF) obtained by Independent Component Analysis (ICA). Simulations demonstrate the robustness of this method. In addition, this invisible watermarking method can be applied to protect the visible-watermarked image. That is to say, we can claim the ownership of the image after visible watermark removal by the invisible watermark.
