Secure Transmission of Information by LSB Encoding Technique using Audio Steganography and Cryptography

In this paper, we deal with Steganography where Steganography is the art and science of communicating in a way which hides the existence of the communication. [1]The goal of steganography is to hide messages inside other harmless message in a way that doesn’t allow enemy to even detect that there is second message present. In an audio Steganographic method [2], we can adjust the bits in such a way so that the stego audio signal resulting from embedding data in higher LSB layer is perceptually indistinguishable from the host audio signal. In addition with Steganography, Cryptography has been added to provide more security for the message.
