Steganographically Encoded Data [PDF]

Steganography is the art of hiding information in ways that prevent its detection. Though steganography is an ancient craft, the onset of computer technology has given it new life.

A Survey of Watermarking Security [PDF]

, 2005
Digital watermarking studies have always been driven by the improvement of robustness. Most of articles of this field deal with this criterion, presenting more and more impressive experimental assessments. Some key events in this quest are the use of spread spectrum, the invention of resynchronization schemes, the discovery of side information channel,

Shape quality measurement for 3D watermarking schemes

, 2006
Shape quality assessment is a new challenge for a wide set of 3-D graphics applications and particularly for emerging 3-D watermarking schemes. In order to measure distortions new metrics have to be drawn between an original 3-D surface and its deformed ...

Watermarking Recommender Systems

Proceedings of the 33rd ACM International Conference on Information and Knowledge Management
Recommender systems embody significant commercial value and represent crucial intellectual property. However, the integrity of these systems is constantly challenged by malicious actors seeking to steal their underlying models. Safeguarding against such threats is paramount to upholding the rights and interests of the model owner.

Best Watermarking Selection for Free-View Point Television

, 2007
The recent advances in Image Based Rendering (IBR) has pioneered a new technology, free view point television, in which TV-viewers select freely the viewing position and angle by the application of IBR on the transmitted multi-view video.

Composability in Watermarking Schemes

Software watermarking allows for embedding a mark into a piece of code, such that any attempt to remove the mark will render the code useless. Provably secure watermarking schemes currently seems limited to programs computing various cryptographic operations, such as evaluating pseudorandom functions (PRFs), signing messages, or decrypting ciphertexts (
