Our method exploits high energetic magnitude frequency components of speech spectrum to hide the secret text. The energy level of each magnitude component is evaluated, and considered only if it is high enough to embed secret data. A frequency maskmg threshold is then calculated for each energetic frequency magnitude component to decide where to embed the secret text. As a result, the initial energy of the cover speech spectrum is slightly modified and the dIstortion error is always kept under the mask. The objective and subjective evaluations show that introducing the energy-based frequency masking 0l?ens new frontiers in text-in-speech steganography since hIgher bit rate text embedding was achieved while obtaining a stego-speech with unnoticeable distortion. © 2010 IEEE.enPermission to reuse abstract has been secured from Institute of Electrical and Electronics Engineers Inc.Bit ratesDistortion errorsDynamic energyEnergy levelFFT based steganographyFrequency componentsInitial energyMasking propertiesSecret dataSpeech spectraSubjective evaluationsText-in-speech hidingFast Fourier transformsMechatronicsSteganographyElectron energy levelsConference PaperCopyright : 2010 IEEE.
