Indeed, the proposed watermarking scheme is very fragile to malicious tampering while allowing non-malicious processing.ĭay by day, the transmission or sharing of digital information online is increasing due to the fact that Internet usage has become somewhat of an addiction for the majority of people. In addition, it is capable of distinguishing intentional attacks from incidental modifications. Simulation results demonstrate that the proposed scheme jointly achieves a good perceptual quality and a high watermark capacity. This latter is efficiently hidden in the wavelet middle frequency sub bands through an additive embedding algorithm and then extracted via a blind detection method.

QR code generation technique as well as Arnold transform are used to boost the security aspect of the watermark. A content-based authentication signature is firstly generated by extracting reliable features from regions of interest. Indeed, we propose herein a singular value decomposition (SVD) and discrete wavelet transform (DWT) based semi fragile watermarking scheme for video content authentication.

Thus, video tamper detection is revealed as a big challenge for multimedia security field researchers. With the development of advanced multimedia editing tools, numerous unauthorized manipulations are easily doable to surveillance systems video files. Compared with several methods found in the literature, the proposed method gives a better robustness. The experimental results demonstrate that the proposed method can achieve a very good transparency, while being robust against various kinds of attacks such as filtering, noising, compression, and frame collusion. The watermark information is embedded by Quantization Index Modulation which is a blind watermarking algorithm. In doing so, the number of frames to be processed is consequently reduced and a better quality of the watermarked video is also ensured since the human visual system cannot notice the variations in fast moving regions. While most of the existing watermarking schemes embed the watermark in all the video frames, which is time-consuming and also affects the perceptibly of the video quality, the proposed method chooses only the fast motion frames in each shot to host the watermark. In this work, a novel and efficient digital video watermarking technique based on the Singular Value Decomposition performed in the Multiresolution Singular Value Decomposition domain is proposed.
