Abstract	Steganography is a concept of hiding information in order for data to remain safe and unhandled by eve droppers. In this paper we are demonstrating a way to transmit data from sender to receiver without being handled by eve through a new technique of steganography. We are using an audio file for hiding our data as audio are very less judged to changes made to them. Audio files in wav form are represented as values of amplitude with given sample rate. The technique is to read the file to be sent in binary form. It has been done by taking corresponding pairs of local maxima and minima of amplitude for the audio file and uplift or depress the values between these pairs depending on whether we have a zero or one in the file to be sent to the sender. Other than that the file to be sent is locked with a password. We compare this file with the original and then the difference in amplitude values between pairs of maxima and minima give us the corresponding binary bit of the file, thus regenerating the file at the receiver using the password which is sent to the receiver separately. For that, first the receiver sends his own transformed voice through a channel with sender knowing about the changes done to it. The sender makes a copy of this transformed voice and gets the original voice by making all changes that receiver has done. In that transformed voice sender attaches the password of the file through steganography technique used here and the password to unlock it is, receivers own original voice. The steganography technique used here and the way to generate new passwords are novel approach. The proposed methodology is very safe for text file transmission.
