| Abstract In this paper, method of steganography in Audio is presented to hide secret information in audio file. Keeping out date of sight in audio is a difficult task due to the extremely high sensitivity of the Auditory System. The current work deals with embedding the secret text message in frequency domain of audio file. The proposed method contained two stages: the first embedding phase and the second extraction phase. Transformation the audio file from time to frequency domain is achieved in the first phase utilizing 1-level linear wavelet decomposition technique and only high frequency is used for hiding secreted message. The text message encrypted using RC5 algorithm then encrypt the result with Rijndeal algorithm. Finally; the Least Significant bit (LSB) algorithm used to hide secret message in high frequency. The proposed approach tested in different sizes of audio file and showed the success of hiding according to (PSNR) equation. Keywords: -Steganography in Audio, RC5 algorithm, Rijndeal algorithm, LSB algorithm, Wavelet transform. | ||
