With rapid growth in communication, Security is one of the important issue for privacy and authentication purpose. Also for military applications data encryption plays a vital role & to achieve such encryption Watermarking Technology is used. For Digital Media, Digital watermarking is one technology is used to ensure and facilitate for data authentication, copyright protection and security etc. Digital watermarking techniques are more robust, transparent, secure, invert ability (reversible) and complex for decryption and verification as compared to other watermarking methods. Due to transparent watermarking no artifacts or quality loss happens in original image. The success of the Internet, cost-effective and popular digital recording, storage devices and the promise of higher bandwidth, quality of service for both wired and wireless networks have made it possible to create, transmit, replicate, and distribute digital content in an effortless way. Digital video watermarking technique was introduced by Hembrooke in 1954. Watermarking is a concept of embedding special symbol or logo or pattern watermark, in to video so that some copyright information is fed into it. This information can inform users about authority to permit the use of data, it can later prove for ownership, identify misappropriate persons, tracking of the video [1]. In this paper, we proposed a digital video watermarking with authentication for tutorial video using Multi-wavelet. In first host video is separated into video shots. Then from each video shot one video frame is selected for embedding watermark. Each identical frame of video is decomposed into 3-level DWT, then select higher sub-band coefficients to insert the watermark and the watermark are embedded to these coefficients and thus guarantee perceptual unobtrusive of watermark . The paper represents the complete software implementation of 3-Level DWT algorithms and to have more secure data a secret key is used. The secret key is given to watermark image during embedding process and while extracting the watermark image the same secret key is used.
