Security Enhancement: Combining Cryptography and Steganography

Abstract

In today's world of high technology, it is not safe to share confidential and important data on any network. Intruders are always in wake of it. They hack the data and use it for their benefit. These malicious people try to gain benefit, get attention, or to harm someone. In either case, message sender or receiver has to pay the price. To avoid these undesirable acts, Steganography and cryptography are used together to ensure security of the covert and secure message. One of the most efficient and secure algorithms is Data Encryption Standard (DES). Steganography is the art and science of writing hidden messages in such a way that no-one apart from the sender and intended recipient even realizes there is a hidden message.
