Abstract

Over the past several years there has been an apparent shift in research focus in the area of digital steganography and steganalysis - a shift from primarily image based methods to a new focus on broader multimedia techniques. More specifically the area of digital audio steganography is of prime interest. We introduce a new high capacity, covert channel data embedding and recovery system for digital audio carrier files using a key based encoding and decoding method. It will be shown that the added information file is interleaved within the carrier file and is fully indexed allowing for segmented extraction and recovery of data at chosen start and stop points in the sampled stream. The original audio quality is not affected by the addition of this covert data. The embedded information can also be secured by a binary key string or cryptographic algorithm and resists statistical analytic detection attempts. We will also describe how this new method can be used for data compression and expansion applications in the transfer and storage of digital multimedia to increase the overall data capacity and security.
