Abstract

Many steganography schemes seek to improve the transmission of important and sensitive information through insecure channels. Audio steganography exploits audio files to transfer that information over public communication channels. This paper proposes a new audio steganography scheme to secure transmission of speech messages using contourlet transform and duffing oscillator. Improvement in the security, hiding capacity, and maintenance of the transparency of the audio signals are contributed by this scheme. Contourlet transform produces a wider spread data coefficient than its input samples. Secret speech samples are hidden into some of these coefficients. The duffing oscillator is used to scramble the cover samples before embedding secret speech and then it is exploited to give the embedding process more immunization against piracy. So, the enhancement in the security level is paralleled with the employing of a duffing oscillator in the proposed scheme. The performance results of the proposed scheme indicate that high hiding capacity up to 80% from the size of covered audio can be achieved and it is corresponding to good quality, secure and transparency for both transmitted audio and retrieved secret speech.
