Our project, Data Hiding in Audio files is the software developed for hiding information which uses the technology called as Stenography –derived from the Greek words meaning, “Covered writing”, is the art of hiding information in ways that prevent its detection.
The proposed system uses Audio file as a carrier medium which add another step in security. The objective of the newly proposed system is to create a system that makes it very difficult for an opponent to detect the existence of a secret message by encoding it in the carrier medium as a function of some secret key and that remains as the advantage of this system.
Aim of the project
We are of the belief that the easiest way to keep something from prying eyes is to place it right in front of the person looking for it and make it look as innocuous as possible. Everyone has a taste for a certain kind of music. Hence, it is more than likely that the person will have that kind of music on the storage device of his computer. Also, it is quite common case where people share and transfer different music files to one another. If one were able to hide the message can be. Also, transfer of this message can be done quite conveniently without raising any eyebrows. Our aim is to come up with a technique of hiding the message in the audio file in such a way, that there would be no perceivable changes in the audio file after the message insertion. At the same time, if the message that is to be hidden were encrypted, the level of security would be raised to quite a satisfactory level. Now, even if the hidden message were to be discovered the person trying to get the message would only be able to lay his hands on the encrypted message with no way of being able to decrypt it.
Java tool is used to perform Data hiding in an Audio file and the Operating System used is Windows 9x, 2000, XP. There are many algorithms available to achieve this. The need of algorithm is to develop concepts and a practical embedding method for Audio files that would provide high steganographic capacity without sacrificing security. The algorithm used in our project is PBE (MD5) algorithm. This algorithm is chosen because it provides more security.
