Data Security using Combination of Steganography and Cryptography

Abstract

With the passage of time data protection is the most evolving topic of Information Security. However steganogarphy is less used, Cryptography is employed worldwide extensively in this area. Combination of both is very effective which is discussed in this paper. This paper proposes the technique of securing data by first using cryptology and then encodes the encrypted data using steganography. This makes it almost impossible for any individual cryptanalyst or a steganalyst to intrude the hidden message unless existence of hidden communication as well as encryption technique is known to the intruder. This scheme can be used to transmit data securely and covertly over wired as well as wireless media.
