INTRODUCTION
THIS document discusses our 412 design project, which
was to design a data hiding application using
steganography. The purpose of this project was to create a
user friendly steganography application that allows users to
hide private data in image files. Our goal was to make our
steganography application less vulnerable to steganalysis than
the existing steganography tools on the market.
Steganography is the process of hiding a secret message
within another message. Steganography can be an invaluable
tool in maintaining confidentiality, which is one of the three
policies computer security is concerned with, along with
integrity and availability.
RELATED WORK
There are many steganography tools which are capable of
hiding data within an image. These tools can be classified into
five categories based on their algorithms: (1) spatial domain
based tools; (2) transform domain based tools; (3) document
based tools; (4) file structure based tools; and (5) other
categories such as video compress encoding and spread
spectrum technique based tools [7].
CONCLUSION
This paper introduced the concept of steganography and
steganalysis as well as the methods for carrying these out. It
also presented the authors’ application which was
demonstrated to be more secure than current applications
against statistical attacks commonly used in steganalysis.
Recommended future improvements for the application were
presented in the last section of the paper.
We believe that steganography when combined with
encryption provides a secure means of secret communication
between two parties. Our application, with its image analysis
and ranking capability is a significant improvement on current
steganography tools.
