Hiding Secure Data in Audio, Text & Image BY Steganalysis

Steganography is the method of hiding any secret information like password, text, and image, audio behind original cover file. In this paper we proposed the audio-image crypto steganography which is the combination of image steganography and audio steganography using computer forensics technique as a tool for authentication. Our aim is to hide secret information behind image and audio of video file. As video is the application of many still frames of images and audio, we can select any frame of video and audio for hiding our secret data. Suitable algorithm such as 4LSB is used for image steganography and phase coding algorithm for audio steganography. v
