Countering Audiovisual Content Piracy: A Hybrid Watermarking and Fingerprinting Technology

Protecting the copyright of multimedia content is required to discourage illegal distribution, broadcasting and sharing audiovisual content over the spider web. In this paper a hybrid algorithm is propose which combines the benefits of both fingerprinting and watermarking technologies with the objective to authenticate audio-visual Content copyright in spite of transcoding occurrences including compression and geometrics attacks during sharing and distribution on social media; precisely YouTube, Facebook. In the proposed approach a method to enhance security process of the mentioned social media against the most common attacks is proposed, such as geometric distortion embracing cropping resizing rotation. Moreover, the Proposed algorithm contributes to the limitation of H.264 compression attacks flows. In this paper, the host video is operated following the next steps; first, scene change detection is practiced in order to ensure a preeminent computational complexity. Then a hybrid frequency double transform incorporating Discrete Wavelet and Discreet Cosines is processed alternatively to the selected frames in the aim to perform a peak-signal-to- noise-ratio values with a higher compression ratio. Afterwards video fingerprinting is executed heading for tracing the behavior of the video after being published. Experiment results shows new scores of high robustness and versatility in performance for transcoding and sharing multimedia content legally under YouTube.
