Transform domain steganography in DVD video and audio content

This paper is dealing with steganography in DVD content. Classical steganography concerns itself on ways of embedding a secret message in a cover message such as a video stream or audio recording. The embedding is typically parameterized by a key. Without knowledge about this key, it is difficult for a third party to detect or remove the embedded material. Once sicret information was embedded in the cover object, this material is called a stego object [1], [2]. We embed a binary image in both video frames and audio tracks. This modification ensures higher payload and security.
