SteganographY

Aim: - The main aim of the project is to conceal the very existence of information by embedding it within innocuous medium such as a text, image or audio file. This insures that the important data to be transmitted over a network is protected from eavesdropping

This project consisted of 5 different Modules

1) Image Steganography: - Used Last Bit Modification Algorithm to hide the file behind .jpeg or .bmp image.

2) Audio Steganography: -  Used Wavelet Domain Last Bit Modification Algorithm to embed the file in a .wav file

3) Text Steganography: -     We devised our own algorithm to embed a file in a .doc file. This algorithm was based on the observation that                                                    two different ASCII values 0 and 32 represent a same character for all practical purposes.

4) Encryption: -                       For further enhancing the security, our software encrypted the original file using RSA encryption algorithm.

5) Transmission :-                Our software allowed transmitting of the embedded message from one computer to another using sockets                                                   and DLL in VC++.
