Video Watermarking With Digital Signature and Fingerprinting
Milan Gupta, Wei Qi Yan · Advances in information security, privacy, and ethics book series · 2023
A digital watermark, which is embedded in an image sequence or video frames as the form of a binary string or visual logo, is a small size of visible data. Thus, the quality of embedded videos is often slashed due to the watermarking. Comparative video watermarking is a highly innovative method that was designed to unravel this issue. In this chapter, the authors make use of singular value decomposition (SVD) and discrete wavelet transform (DWT) for video watermarking; the authors employed inverse transform (IDWT) to extract the video watermark. The digital signature is also utilised to increase the authenticity of watermarks and verify any changes. The authors combine this approach with digital fingerprinting as well as to get the improved results. Throughout the designed attacks, the merits of the new watermarking paradigm such as robustness, convergence, and stability are attained with security and authenticity by calculating the metrics such as MSE, PSNR, entropy, SSIM, etc.
