Technical report TR02-01. Research in information hiding has grown explosively. A large number of techniques have been proposed to discourage copyright infringement, tampering and unauthorized distribution of digital media (e.g. video, audio, and images). In this paper, we provide an overview of information hiding, outlining its main disciplines (covert channels, steganography, digital watermarking, and anonymity), and some applications current driving interest. We focus on the current status of and prospects for digital watermarking, devoting special attention to a taxonomy based on insertion domain, applicability, and existing algorithms. Finally, we offer an overview of technical progress and analyze some watermarking limitations, culminating in a discussing of some interesting topics for future research. | TRID-ID TR02-01
