Power-spectrum condition for energy-efficient watermarking
This paper presents a model for watermarking and some attacks on watermarks. Given the watermarked signal, the so-called Wiener attack performs minimum mean-squared error (MMSE) es...

On Optimal Watermarking Schemes in Uncertain Gaussian Channels
This paper describes the analytical derivation of a new watermarking algorithm satisfying optimality properties when the distortion of the watermarked signal is caused by a Gaussi...

On a Watermarking Scheme in the Logarithmic Domain and its Perceptual Advantages
Scaling attacks are well-known to be some of the most harmful strategies against quantization-based watermarking methods, as they can completely ruin the performance of the waterm...
