This Project Titled “Data Hiding in Audio files” is the software developed for hiding information which uses the technology called as Steganography –derived from the Greek words meaning, “Covered writing”, is the art of hiding information in ways that prevent its detection.
It is a method akin to covert channels, and invisible links, which add another step in security. A message in cipher text may arouse suspicion while an invisible message is not. Digital stenography uses a host data or message known as a “Container” or “Cover” to hide another data or message in it. The conventional way of protecting information was to use a standard symmetric or asymmetric key system in encryption. Steganography can also be used to place a hidden “trademark” in images, music, and software, a technique referred to as watermarking.
To ensure the privacy of the communication between two parties, various new methods are being developed. Cryptography being the mother to all those projects. However, cryptography is like a tool, it can do as well as it is programmed to do. Also, there are various different techniques that can be implemented to attain a certain level of security. Here we implement a technique for data hiding in audio images, known as Audio file Steganography.
First the audio file which behaves as carrier file is selected. Then a message or a text file to be embedded in audio is selected. Then a key file is selected. The key file contains characters whose ASCII values are taken for encryption. Then the file is embedded in audio using low bit encoding mechanism and extraction of embedded message is being done vice-versa.text -
