Steganography for Hiding Data in Wave Audio Files

Abstract

This project uses code from a full-duplex audio player in C# using the waveIn/waveOut APIs. Now the data is hidden in bitmaps, MIDI tracks and .NET assemblies, it misses one important file format. The missed file can hide lots of bytes without becoming larger, and can be generated in few seconds, so that original files on the disk cannot be stored. It is the time to add wave audio to the list. Data hiding can be used as an alternative to encryption to establish secure communications. The idea is based on the principle of hiding the information to be secured inside an audio file and to establish the communication in a covert way. The important issues involve delectability of the hidden information. Digital steganography 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 Audio file technique known as watermarking. Compression is the reduction in size of data in order to save space or transmission time. For data transmission, compression can be performed on just the data content or on the entire transmission unit (including header data) depending on a number of factors.
