Secure data transmission using video Steganography

It is very essential to transmit important data like banking and military information in a secure manner. Video Steganography is the process of hiding some secret information inside a video. The addition of this information to the video is not recognizable by the human eye as the change of a pixel color is negligible. This paper aims to provide an efficient and a secure method for video Steganography. The proposed method creates an index for the secret information and the index is placed in a frame of the video itself. With the help of this index, the frames containing the secret information are located. Hence, during the extraction process, instead of analyzing the entire video, the frames containing the secret data are analyzed with the help of index at the receiving end. When steganographed by this method, the probability of finding the hidden information by an attacker is lesser when compared to the normal method of hiding information frame-by-frame in a sequential manner. It also reduces the computational time taken for the extraction process.
