Executive Summary

This paper presents a proposal for communication which is major part of daily life of today. The authors are living an age of science.. With the increasing communication traffic demand, data security has become very important field. Lots of data security and data hiding algorithms have been developed in the last decade. They are implementing a method of "Digital Stenography" for image data hiding. Image Steganography system allows an average user to securely transfer text messages by hiding them in a digital image file. A combination of Steganography and encryption algorithms provides a strong backbone for its security.
