Steganography in Audio

Neil JenkinsJean Everson Martina

A program was built to hide an arbitrary file inside audio using three different methods based on current research in the field. Standard libraries were used to compress (with bzip2) and encrypt (using AES) the data before it is embedded. The error-correcting Hamming and Golay codes were implemented to increase the system’s resistance to malicious modification. Finally,the LAME MP3 encoder was integrated to work with one of the methods (echo hiding). The finished project provides a means for secure, discreet communication through a monitored, hostile channel.
