Simultaneous Use of Two Steganography Algorithms to Hide the Human Speech at a Double Rate

With respect to expansion of technology and significant telecommunication developments and the possibility of sending and receiving the information from the long distance, reveals the great significance to keeping information from invalid access. Steganography is a method that hides the information in the form of a masking agent such as images, audio, and video with the high accuracy and security. One of the problems of the steganography methods is to employ a lot of bandwidth while this methods couldn’t transport so much information. The purpose of this study was to embed the audio message in the music signal while doubling length of the hidden message in comparison with length of the music signal
