Abstract :
Analog Gaussian watermarking systems in which transmitted watermarks are reproduced with certain distortion at receivers are addressed in this paper. Achievable distortion regions of private analog Gaussian watermarking systems and public analog Gaussian watermarking system are determined with respect to the mean-squared error distortion measure, with and without joint compression, respectively. The results show that, interestingly, if watermark sources and host signal sources are independent, then the achievable distortion regions of private analog Gaussian watermarking systems and public analog Gaussian watermarking systems coincide.
