Ioannis Pitas, G. Voyatzis. Applications of Toral Automorphisms in Image Watermarking, (ICIP'96) IEEE International Conference on Image Processing, September. Vol. 2 1996. pp. 237-240. [.Z]   ABSTRACT: Digital watermarking methods have been recently proposed for various purposes and especially for copyright protection of multimedia data. The digital watermark is embedded in a digital signal or an image and must be unrecognizable by unauthorized persons and detectable only by the legal copyright owner. In this paper we use toral automorphisms as chaotic 2­D integer vector generators in order to manipulate digital image watermarking. We propose also an embedding algorithm which provides robustness under filtering and compression. | Neil's Homepage | Steganography | JJTC Main Page | Send comments to nfj(at)jjtc(dot)com.
