Data Transmission using Audio Steganography

Data Transmission using Audio Steganography

 Data transmission in public communication system is not secure because of interception and improper manipulation by eavesdropper. So the attractive solution for this problem is Steganography, which is the art and science of writing hidden messages in such a way that no one, apart from the sender and intend recipient, suspects the existence of the message, a form of security through obscurity. Audio steganography is the Scheme of hiding the existence of secret information by concealing it into another medium such as audio file. In the secret message and carrier files are taken as audio files. Before performing the embedding process the secret message is encrypted using a public key cryptography. Thus using the key the secret information is retrieved at the receiver side.
