This paper reviews the role of information theory in characterizing the fundamental limits of
watermarking systems and in guiding the development of optimal watermark embedding …

This tutorial paper reviews the theory and design of codes for hiding or embedding
information in signals such as images, video, audio, graphics, and text. Such codes have …

In this paper, a robust watermarking algorithm using balanced multiwavelet transform is
proposed. The latter transform achieves simultaneous orthogonality and symmetry without …

In order to provide more watermarks and to minimize the distortion of the watermarked
image, a novel technique using the combinational spatial and frequency domains is …

In this paper, a new SVD-based digital watermarking scheme for ownership protection is
proposed. The proposed algorithm solves the problem of false-positive detection. In …

In the last few years, we have seen many new and powerful steganography and
steganalysis techniques reported in the literature. In the following tutorial we go over some …

Steganography is the art of secret communication. Its purpose is to hide the presence of
information, using, for example, images as covers. We experimentally investigate if stego …

Information-theoretic analyses for data hiding prescribe embedding the hidden data in the
choice of quantizer for the host data. We propose practical realizations of this prescription for …

While formal definitions and security proofs are well established in some fields like
cryptography and steganography, they are not as evident in digital watermarking research. A …

A considerable amount of attention has been paid lately to a number of data hiding methods
based in quantization, seeking to achieve in practice the results predicted by Costa (1983) …
