Hiding data is a very important thing nowadays as the data travels over various unsecure networks. To avoid this problem cryptography is used which hides the data or scrambles the users' message, but cryptography alone cannot provide total security as the message is still available to perform cryptanalysis. Steganography hides the existence of the message. Most of the peoples use either cryptography or steganography to improve security. But a combination of both the techniques provides better security. This paper will describe an effective way of using cryptography along with a modification in LSB steganography in images.
