Now a days transfer of information from one system to another system needs more security especially in some applications like militaty etc. It can sent to through different mediums such as audio,video. So to transmit information in secured manner, Steganog raphy is used. Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos meaning "covered, concealed, or protected", and graphein me aning "writing". But we cannot transmit more amounts of hidden data. So we go to the video Steganography using DWT method. In this p aper , we propose a steganography technique which embeds the secret messages in frequency domain. According to different u sers demands on the embedding capacity and quality, the proposed algorithm consists of converting video into frmaes and embedding each secured data within each frame. So more amount of information hide in a single video. Unlike the space domain approaches, secret messages are embedded in the high frequency coefficients resulted from Discrete Wavelet Transform.
