Protecting digital data is becoming increasingly important due to the rapid growth of the internet and technology.A novel watermarking technique is proposed in this paper, which involves embedding both visible and invisible watermarks in a video.Since digital data can be easily replicated without loss of quality, it is important to protect the data. Digital watermarking is a technique for embedding additional information into the host signal to ensure multimedia data security and privacy.Since both watermarks are present in the video frames, it is more resistant to attacks.The watermarking scheme listed here deals with watermark embedding and extraction. The invisible watermark is embedded using the Discrete Wavelet Transform (DWT), and the Peak Signal to Noise Ratio (PSNR) is measured to assess the method's efficacy.The visible watermark is embedded using compound mapping, which improves the video's robustness.
