This paper considers a fingerprinting system where 2 nR W distinct Gaussian fingerprints are embedded in respective copies of an n-dimensional i.i.d. Gaus-sian image. Copies are distributed to customers in digital form, using R Q bits per image dimension. By means of a coding theorem, a rate region for the pair (R Q , R W) is established such that (i) the(More)
—A system which embeds watermarks in-dimensional Gaussian data and distributes them in compressed form is studied. The watermarked/compressed data have to satisfy a distortion constraint, and the watermark has to be recoverable in a private scenario (in which the original data are available at the watermark detector). The performance of the system in the(More)
