Enhancing Network Security using Digital Image Processing, Cryptography & Steganography

Abstract

Quite often, we communicate exceedingly confidential information over a communication network that we want only the recipient to know. How do we protect such information from malicious attacks? Techniques like steganography, encryption and cryptography can be used to keep our data confidential.But, a combination of these techniques would help us keep our data highly confidential while nullifying the short comings of each of them when used individually. In this paper, we address the problem of security breaches using digital image processing. We know that email service providers sell our data to third party companies for their usage and profits. In today’s scenario, security is a major concern while transmitting any information over the network. Security provided by the network is insufficient with the increasing rates of cybercrimes. Therefore, we need to employ other techniques to carefully send our data over the network. In this paper, we explore a number of security techniques that can be combined together to ensure higher levels of security to our data.
