In this paper, we propose an original blind watermarking algorithm robust to local geometrical distortions such as the deformations induced by Stirmark. ... Geometrical distortions are the Achilles heel for many watermarking schemes. ... The difficulty is then to make both approaches work together to be able to cope with any kind of geometric distortion, in particular a combination of global and local geometric attacks. ...doi:10.1109/tip.2006.877311 pmid:16948326 fatcat:fr6uc4jxevb7fgbmmuba2w6dtu
This paper provides a comprehensive survey of M-IoT with an emphasis on architecture, protocols, and applications. This article starts by providing a horizontal overview of the IoT. ... We explore the importance of Quality-of-Experience (QoE) and Quality-of-Service (QoS) for multimedia transmission over IoT. ... Watermarking is used to identify the origin of multimedia content, trace illegal distribution, and block unauthorized access by embedding a unique watermark into multimedia content  . ...doi:10.1109/access.2020.2964280 fatcat:ilihkpik65bdvblyal6rp7tb2y

Moreover, the introduced DVC scalable schemes show a good robustness to errors as the quality of decoded video steadily decreases with error rate increase. ... Further, the issue of privacy protection is addressed for DVC by transform domain scrambling, which is used to alter regions of interest in video such that the scene is still understood and privacy is ...
