A Novel Technique for Data Hiding in Audio by Using DWTS
Preeti Jain, Vijay Kumar Trivedi · 2012
A secure data transfer is limited due to its attack made on data communication internet community. Audio data hiding can be used anytime you want to hide data. 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. In this paper, we propose a novel approach for high capacity audio steganography algorithm based on the wavelet packet transform with adaptive hiding in least significant bits. The adaptive hiding is determined depend on the cover samples strength and bits block matching between message and cover signals. We propose two main stages, Input stage and secret message hiding stage. After the stages of input audio segmenting hide secret message by using preprocessing and developed in matlab.
