| Steganography is the practice of encoding secret information in indiscernible way. Audio Steganography is a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner. It is mainly required for increasing security in transferring and archiving of audio files. Steganography complements rather than replaces encryption by adding another layer of security- it is much more difficult to decrypt a message if it is not known that there is a message. The basic idea of the paper is hide information in cover audio by using linear feedback shift registers LFSR with the Least Significant Bit (LSB) coding to hide data for it and the proposed method hiding data in audio signals using LFSR to select any LSB of audio signals. this proposed method has more security than classical methods because the analysis didn't know any vector used for hide data and proposed method has low noise audio signals than classical method because less number of LSB used for hide data ,the proposed method was applied on two experimental for hiding data and extracting the embedded data in audio signals and applied the noise tests mean squared error (MSE) and Signal-to-noise ratio (SNR) and peak signal-to-noise ratio (PSNR) on it . | ||
