The data Encryption system is used for hiding data by supervised trained dictionary. It involves concealing the secret text inside the cheating text. Then cheating text is hiding in Audio file. If the cheating text is intercepted, the secret text may still be undetected. There are many reasons to hide data but most important is to prevent unauthorized persons from becoming aware of the existence of a message. Hidden message is information that is not immediately noticeable, and that must be discovered or uncovered and interpreted before it can be known. We propose a novel approach for generating cheating text and hiding cheating text in audio file this high capacity audio algorithm based on the wavelet packet transform with adaptive hiding in least significant bits. The adaptive hiding is determined depend on the cover signal strength and bits block matching between message and cover signals.
