ABSTRACT
This Project Titled “Data Hiding in Audio files” is the software developed for hiding information which uses the technology called as Stenography which is the art of hiding information in ways that prevent its detection.. A message in cipher text may arouse suspicion while an invisible message is not. The conventional way of protecting information was to use a standard symmetric or asymmetric key system in encryption. Stenography can also be used to place a hidden “trademark” in images, music, and software, a technique referred to as watermarking.Stenography, if however used along with cryptography then the message will become quite secure as far as cryptanalytic attacks are concerned. Now, if this cipher text is embedded in an image, video, voice, etc., it is even more secure. If an encrypted message is intercepted, the interceptor knows the text is an encrypted message. With Stenography, the interceptor may know the object contains a message.
When performing data hiding on audio, one must exploit the weakness of the Human Auditory System (HAS), while at the same time being aware of the extreme sensitivity of the human auditory system. 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.
