“Analysis & Design of multiple watermarking in a Video for Authentication & Copyright Protection”

Abstract — Watermarking has been used time and again for authentication & security of Video. Digital watermarking refers to embedding watermarks in a multimedia documents and files in order to protect them from illegal copying and identifying manipulations. Watermarking is a promising solution to protect the copyright of multimedia data through Transcending, because the embedded message is always included in the data. Because of the fidelity constraint, watermarks can only be embedded in a limited space in the multimedia data. Watermarking techniques can be classified into two types:-1. Spatial & 2. Frequency Domain. In this work proposed to design a new watermarking technique which involves embedding two or more messages or images in a single frame of video for the purpose of security and repeat the same process for N-frames of the video for authentication of whole video
