A Hybrid technique of Video Watermarking in Wavelet domain and Scan based Encryption Method

Abstract- Security of digital products (audio, video, image, and text) on the internet is very essential these days, for these digital watermarking techniques are used. Digital watermarking is the process of embedding data into digital multimedia content. This is used to validate the reliability of the content or to recognize the identity of the digital content's owner. Sophisticated watermarking techniques have recently been developed, and they can be used to embed in printed text, graphics, or images as well as in digital images, graphics, audio, or video. This present survey is on DWT (Discrete Wavelet Transform) technique used in watermark. DWT transform more computationally efficient than other transform methods, because of its outstanding localization properties which offer the compatibility with the Human Visual System (HVS)
