Ioannis Pitas, G. Voyatzis. Chaotic Mixing of Digital Images and Applications to Watermarking, (EMAST'96) European Conference on Multimedia Applications Services and Techniques, Louvain-La-Neuve,. Vol. 2 1996. pp. 687-695. [.Z]   ABSTRACT: This paper presents a method for embedding watermarks (some call them signatures) in digital pictures. The signatures are considered to be digital images with few grey levels, which are embedded in digital grey or color pictures. The extraction of the watermark, by an unauthorized person, is impossible since a chaotic mixing of the code takes place. Our study is based on the theory of toral automorphisms which may be proved to be a useful tool in digital copyright protection. | Neil's Homepage | Steganography | JJTC Main Page | Send comments to nfj(at)jjtc(dot)com.
