Final Year PROJECT SYNOPSIS
 
Project Definition

 
“COVERT COMMUNICATION BETWEEN USING DIGITAL IMAGES”

We have implemented the hiding of data in digital images in spatial domain ( Least Significant Bit (LSB))  and in transform domain (Discrete Cosine Transform (DCT)). We have used Visual C++ to implement the LSB part and for the DCT we have used MATLAB.
Brief DESCRIPTION

In the past decade,  steganography was present in various forms e.g. shaving of the head, using invisible ink etc… Steganography as we all know is hiding the very existence of data which separates from the encryption of data in which the data which is transferred is always visible   in some unreadable form.
In today’s world or the digital era we are giving steganography new bounds. By this line  we mean that we are hiding the important message of the user in the digital image, then transferring the stego-image ( image  + data ) to the other end where the original message can be extracted using the user authentication.
The intruder is thus unaware of the communication taking place between the intended users. Hence we enhance the security of the message against any tampering, leakage, modification etc… Thus we are providing a very efficient software in today’s world which preserves the original message at any cost which can be used for many purposes such as :

Between two branch officers of the same company you can easily transfer the tender information

Across the boundaries of two nations,  violation of the human rights can be made aware of.  Digital watermarking or copyright protection can be provided. Some anti-social elements can also take advantage of this software to create disasters.
