Executive Summary

This paper introduces a new method of securing image using cryptographic and steganographic techniques. The science of securing a data by encryption is Cryptography whereas the method of hiding secret messages in other messages is Steganography, so that the secret's very existence is concealed. The term 'Steganography' describes the method of hiding cognitive content in another medium to avoid detection by the intruders. The proposed method uses cryptographic and steganographic techniques to encrypt the data as well as hide the encrypted data in another medium so the fact, that a message being sent is concealed. The image is concealed by converting it into a ciphertext using SDES algorithm with a secret key,which is also an image, and sent to the receiving end securely.
