| Popis: | International audience; In this paper, we propose a new semi-fragile watermarking scheme in the frequency domain for surveillance videosauthentication. Our system starts operating by generating a binary watermark based on a novel watermarkconstruction process. This latter combines Speeded Up Robust Features (SURF) and Maximally Stable ExtremalRegions (MSER) detectors to extract frames relevant features that can resist common attacks while being fragileto intentional manipulations. Furthermore, the watermark security is improved using torus automorphism mapping.For the embedding process, Regions of Interest (ROI) are detected and then used as watermark holders. Theseregions are decomposed into different frequency sub-bands using Singular Value Decomposition (SVD) as wellas Discrete Wavelet Transform (DWT). Then, the watermark is embedded in selected bands following an additivemethod. A blind detection is conducted to extract the hidden signature from the watermarked video. Evaluationresults show that the proposed scheme is suitable for authentication purpose since it efficiently discriminatesmalicious manipulations from non-malicious ones. Besides, it preserves a high level of perceptual quality |
