Digital audio, video, images, and documents are flying through cyberspace to their
respective owners. Unfortunately, along the way, individuals may choose to intervene and …

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 …

Network security is important for information protection in open, secure, or covert
communications. One such requirement is to achieve high-rate communications between …

An information-theoretic model for image watermarking and data hiding is presented in this
paper. Previous theoretical results are used to characterize the fundamental capacity limits …

This paper presents a novel singular value decomposition (SVD)-and vector quantization
(VQ)-based image hiding scheme to hide image data. Plugging the VQ technique into the …

With the advances of the digital information revolution and the societal changes they have
prompted, it has become critical to facilitate secure management of content usage and …

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 …

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 …

With the increasing number of new steganographic algorithms as well as methods for
detecting them, the issue of comparing security of steganographic schemes in a fair manner …

Rates of reliable transmission of hidden information are derived for watermarking problems
involving parallel Gaussian sources, which are often used to model host images and audio …
