Resolution and quality scalable spread spectrum image watermarking
If digital watermarking is to adequately protect content in systems which provide both resolution and quality scalability, then the watermarking algorithms used must provide both ...

Watermarking of MPEG-2 video in compressed domain using VLC mapping
In this work we propose a new algorithm for fragile, high capacity yet file-size preserving watermarking of MPEG-2 streams. Watermarking is done entirely in the compressed domain,...

Exposing digital forgeries by detecting inconsistencies in lighting
When creating a digital composite of, for example, two people standing side-by-side, it is often difficult to match the lighting conditions from the individual photographs. Lighti...

An SVD-based audio watermarking technique
We present a non-oblivious, extremely robust watermarking scheme for audio signals. The watermarking algorithm is based on the SVD of the spectrogram of the signal. The SVD of the...

A Bayesian image steganalysis approach to estimate the embedded secret message
Image steganalysis so far has dealt only with detection of a hidden message and estimation of some of its parameters (e.g., message length and secret key). To our knowledge, so fa...

A fragile watermarking scheme for 3D meshes
In this paper, we propose a new fragile watermarking scheme for 3D meshes. Firstly, the watermark information is adaptively embedded into the mesh geometry by slightly adjusting t...

Capacity of steganographic channels
—This work investigates a central problem in steganography, that is: How much data can safely be hidden without being detected? To answer this question a formal definition of st...

LSB steganalysis based on high-order statistics
We propose a general framework for the detection of the LSB steganography using digital media files as cover objects. The new framework exploits high-order statistics of the samp...

Composite signature based watermarking for fingerprint authentication
Digital watermarking is a technology to hide information in digital media. We extend the digital watermarking technique Phasemark™, originally developed solely for image authent...
