Enhancement of Data Hiding Capacity in Audio Steganography
IOSR Journal of Computer Engineering · 2013
Nowadays, a lot of applications are Internet-based and demand of internet applications requires data to be transmitted in a secure manner.Data transmission in public communication system is not secure because of interception and improper manipulation by eavesdropper.So a technique for secure transmission of messages called Steganography, which send the messages in such a way that existence of the message is concealed.Audio Steganography is the scheme of hiding the existence of secret information by concealing it into an audio file.In this paper we will discuss how audio file can be used as carrier to hide the secret information.In this paper we also proposed a system that will enhance the data hiding capacity in Audio Steganography using LSB method.we will use last 4 LSB's instead of a single LSB , this will enhance the data hiding capacity of carrier file.
