In this paper we will overview the use of data hiding techniques in digital images. In
particular we will describe how one can use Steganography to hide information in a digital …

Information-hiding techniques have recently become important in a number of application
areas. Digital audio, video, and pictures are increasingly furnished with distinguishing but …

The least-significant-bit (LSB)-based approach is a popular type of steganographic
algorithms in the spatial domain. However, we find that in most existing approaches, the …

Multimedia watermarking technology has evolved very quickly during the last few years. A
digital watermark is information that is imperceptibly and robustly embedded in the host data …

We present a new method of digital steganography, entitled spread spectrum image
steganography (SSIS). Steganography, which means" covered writing" in Greek, is the …

In the last few years, a large number of schemes have been proposed for hiding copyright
marks and other information in digital pictures, video, audio and other multimedia objects …

A spread-spectrum-like discrete cosine transform (DCT) domain watermarking technique for
copyright protection of still digital images is analyzed. The DCT is applied in blocks of 8/spl …

We describe a class of attacks on certain block-based oblivious watermarking schemes. We
show that oblivious watermarking techniques that embed information into a host image in a …

An effective dual watermark scheme for image tamper detection and recovery is proposed in
this paper. In our algorithm, each block in the image contains watermark of other two blocks …
