Hide Secret Massages in Audio File in Secure Wireless Communication using Embedded Algorithm

Now a day, rapid growth of Internet and its users increases range of data types which emphasize the security problem and also flood of multimedia contents in the structure of transmission of such data. The Encryption system for data is used for hiding data and messages by supervised trained dictionary. It involves hiding the secret text inside the cheat ing text. This cheating text is then hiding in Audio file. If this cheating text is intercepted by unauthorized person, the secret text may still be undetected by them. There are many reasons to hide data but most important is to put off unauthorized persons from becoming conscious of the existence of such a message in the network of communication. This hidden message is information which is not immediately noticeable which must be discovered or uncovered and interpreted before it can be known to anybody. This paper proposes an approach for generating cheating text and hiding cheating text in audio/sound file this high capacity audio algorithm based on the wavelet packet transform with adaptive hiding in LSB (Least Significant Bits). The adaptive hiding is determined depend on the cover signal strength and bits block matching between message and cover signals.
