Efficient secrecy can be achieved at least in part, by implementing steganograhy techniques. In this paper, we propose a new technique to hide text in wideband speech in noise free environment. We opted to work in the Fourier transform domain and hide the digital information within high frequency components. More precisely, our method exploits selected locations from the high-frequencies part of the cover speech to hide the secret text. We better preserve with high fidelity the spectrum shape of the speech carrier by employing an embedding rather than a replacement operation on the secret text. Our simulation results show that this approach maintains the robustness of the cover signal and achieves a higher hiding capacity. © 2010 IEEE.enPermission to reuse abstract has been secured from Institute of Electrical and Electronics Engineers Inc.Digital datasDigital informationFFT based steganographyHiding capacityHigh fidelityHigh frequencyHigh frequency componentsNoise-free environmentsReal-life applicationsSimulation resultSpectrum shapeSpeech spectraText in speech hidingConference PaperCopyright : 2010 IEEE.
