Abstract

Steganography is the art of hiding the fact communication is taking place, by hiding information in other information.Many different carrier file formats can be used,but digital images are the most popular because of their frequency on the internet.This paper introduces two new methods where in cryptography and steganography are combined to encrypt the data as well as to hide the data in another medium through image processing . This paper secur ing the image by encryption is done by DES algorithm using the key image. The encrypted image can be hide in another image by using LSB techniques,so that the secret’s very existence is concealed. The decryption can be done by the same key image using DES algorithm.
