Robust Video Watermarking Resilient To Inadvertent Attacks
Nhayan Abdulla, K. A. Navas · 2020
The security of information contents exists as a problem for researchers about various techniques discussed in the reviews for protecting digital rights and copyright authentication. The method for providing secureness to right-owners is digital watermarking; i. e, the method of embedding secret text message in the file. The availability of online contents of audio clip, images and videos are rapidly growing. The efficiency of watermarking algorithm mainly follows on the properties of robust and also imperceptibility.Modern watermarking methods are capable of successfully attacking older watermarking methods. That arises the importance of designing recent and robust watermarking methods for resisting the attacks of watermarked videos. We developed in this project, relating new video watermarking technique based on combination of Discrete Wavelet Transform(DWT) and Singular Value Decomposition (SVD). To understand the robustness of watermarking algorithm, the watermarked video is subjected to inadvertent attacks. Performance analysis were done using evaluation metrics like NCC, PSNR and BER. The lower entropy frames are used for text watermark embedding. Compared the performance with existing methods in presence and absence of unintentional attacks like cropping, blurring, and adding noises like salt and pepper noise, speckle noise.
