Abstract: The Problem of illegal manipulation and distribution of digital video is becoming a big issue. To solve this problem, a new technology has been proposed. Basically, it is a process of embedding copy right information into bit streams of any video. In this particular scheme, the randomly segmentation and reconstruction of embedded secrete data is done without knowing the original host video. During the embedding process, secret data is embedded in individual video frames using the DWT’s frequency domains. In this proposed work, a DWT video watermark technique has been introduced for securing data. We proposed a Haar wavelet based digital watermark technique to secure data. In Haar wavelet, Dyadic equation is used to embed the copy right information in video bit streams.
