Fame of digital video foundation is accompanied by the necessity for copyright safeguard to preclude illicit copying and distribution of digital video. . As a procedure of copyright security, digital video watermarking has recently emerged as a enormous area of curiosity and an extraordinarily energetic subject of study. In this article, the targeted semi-visible watermarking is approached using Daubechies Wavelet functions and Principal component analysis (PCA) based approach, the watermark or message embedded into cover image, prior to it. The embedding is carried out in independent components of PCA domain, by the virtue of alpha, the secret key. Experimental setup reveals that embedding a watermark can be performed more faster and more robust.
