Abstract
A system which embeds watermarksin n-dimensional i.i.d. Gaussian images and distributesthem in compressed form is studied.The performance of the system in the presence of Gaussianattacks is considered, and the region of achievablewatermarking and quantization rates is establishedunder constraints on image distortion and watermark detectability.The performance of related schemes is also discussed.
