A Hybrid technique of Video Watermarking in Wavelet domain and Scan based Encryption Method
Monika Sharma,  Archana Tiwari
Security of digital products (audio, video, image, and text) on the internet is very essential these days, forthesedigital watermarking techniques areused. Digitalwatermarking is the process of embedding data into digital multimediacontent. 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 (DiscreteWavelet Transform) technique used in watermark. DWT transform more computationally efficient than other transformmethods, because of itsoutstanding localization properties which offer the compatibility with the Human Visual System(HVS).
Keywords- Digital Video Watermarking, DWT (Discrete Wavelet Transform), Inverse DWT, Pseudo - random number
