A Novel Digital Watermarking Technique for Video Copyright Protection: An Advanced Study | Chapter 9 | Theory and Practice of Mathematics and Computer Science Vol. 10

 Because of the rapid rise of the internet and technology, protecting digital data is becoming increasingly critical. This research proposes a novel watermarking methodology that involves inserting both visible and invisible watermarks in a video. Because digital data may be quickly reproduced without sacrificing quality, it is critical to safeguard it. Digital watermarking is a method of encoding additional information in the host signal to secure the security and privacy of multimedia data. It is more resistant to attacks because both watermarks are present in the video frames. The watermarking methodology presented here is for embedding and extracting watermarks. The Discrete Wavelet Transform (DWT) is used to incorporate the invisible watermark, and the Peak Signal to Noise Ratio (PSNR) is used to evaluate the method's effectiveness. Compound mapping is used to insert the visible watermark, which increases the video's stability.
