Steganography means, a method for hiding secret information for example password text or image inside a cover file. In this paper, a combination of audio steganography and image steganography is used and also forensic technique is used for authentication. The aim is to hide secret data in the audio and image of a video file. Video has so many still frames of image and audio, we can select any frame for hiding our data. Two algorithms can be used for this purpose.4LSB for image steganography and phase coding algorithm for audio steganography.
