Among the many techniques available for informationconcealment, those based on spread spectrummodulationshave proven to yield improved results when robustness against attack is at...
In this work, an adaptive image compression algorithm is proposed based on the prediction of AC coefficients in Discrete Cosine Transform (DCT) block during reconstruction of image...
We propose to embed watermarks by modifying the texture mapping information of 3D models rather than modifying the geometry information or texture image as existing works do. We p...
This paper presents the constraints involved by MPEG-4 to copyright protection systems based upon watermarking technology. It proposes also an assessment methodology in order to ev...
Background: The aim of this paper is to demonstrate the application of watermarks based on DNA sequences to identify the unauthorized use of genetically modified organisms (GMOs) ...
