摘要：novel LSB steganographic method of embedding textual information in an audio file. In the proposed technique, first the audio file is sampled and then an appropriate bit of each alternate sample is altered to embed the textual information. In this approach the perceptual quality of the host audio signal was not to be degraded. RSA Secret keys are used for secure transmission of data. Signal-to-noise ratio a standard measure of the amount of background noise present in a speech signal is calculated.
