Academic IT Project Documents: DATA HIDING USING STEGANOGRAPHY C#.NET PROJECT REPORT

Abstract

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. 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. Low-bit encoding is the one of the simplest way to embed data into other data structures. By replacing the least significant bit of each sampling point by a coded binary string, we can encode a large amount of data in an audio signal. This Project Titled “Data Hiding in Audio Signal” is the software developed for hiding information which uses the technology called as Steganography It is a method akin to covert channels, and invisible links, which add another step in security.
