Stego encrypted message in any language for network communication using quadratic method

Abstract

Problem statement: Extensive use of digital media like text, images, audio and video on the internet generated a requirement for providing traffic security. For carrying out confidential communications over public networks, it was found that simply concealing the contents of a message using cryptography was not adequate. Concealing the very fact that a communication has taken place could provide an additional layer of security. In this study several methods are used to fulfill this goal. This study produced new procedures in steganography for hiding ciphered information inside a digital color bitmap image. Approach: In this project we were using quadratic method depending on the locations concluded by the binary image, beside of public key cryptography. Results: Very immune information from hacking and breaking. Conclusion: In this study, we had concluded that the conjunction between cryptography and steganography produce immune information. The Unicode made any language to be used. The conversion to binary image is for selecting the locations of the message to be saved and it gives somewhere randomly locations for the pixels to be used for hiding. © 2010 Science Publications.
