Information-theoretic resolution of perceptual WSS watermarking of non i.i.d. Gaussian signals
Stéphane Pateux, Gaëtan Le Guelvouit, Christine Guillemot
The theoretical foundations of data hiding have been revealed by formulating the problem as message communication over a noisy channel. We revisit the problem in light of a more ge…
Trellis-coded quantization for public-key steganography
Gaëtan Le Guelvouit
This paper deals with public-key steganography in the presence of a passive warden. The aim is to hide secret messages within cover-documents without making the warden suspicious,…
Informed stego-systems in active warden context: statistical undetectability and capacity
Sofiane Braci, Claude Delpha, Rémy Boyer +1
Several authors have studied stego-systems based on Costa scheme, but just a few ones gave both theoretical and experimental justifications of these schemes performance in an activ…
The Good, the Bad, and the Ugly: three different approaches to break their watermarking system
Gaëtan Le Guelvouit, Teddy Furon, François Cayre
The Good is Blondie, a wandering gunman with a strong personal sense of honor. The Bad is Angel Eyes, a sadistic hitman who always hits his mark. The Ugly is Tuco, a Mexican bandit…
Wide spread spectrum watermarking with side information and interference cancellation
Gaëtan Le Guelvouit, Stéphane Pateux
Nowadays, a popular method used for additive watermarking is wide spread spectrum. It consists in adding a spread signal into the host document. This signal is obtained by the sum…
