Multi-Part Data Hiding in Audio Steganography

Abstract: In the networking scenario, the information is shared among the users and this information should be confidential and authenticated to the receiver. The information should be kept in secure medium for protect from the intruders. So the data hiding technique should be used for keep the information available to the users.. The basic idea of proposed method is that the host signals (the sound wave cover media) undergoes pre-processing. The secret data is then hidden in a pre-processed fragmented sound wave using a traditional Steganography technique. The least significant-bit (LSB) based technique are very popular for Steganography in spatial domain. The simplest LSB technique simply replaces the LSB in the fragmented or multi-part audio file with the bits from secret information. The proposed methods offer high quality of Audio file with no loss of audio data. Only minor changes in the contents of the audio file occur, which are indiscernible to human ears. The algorithm has been proposed for Multi-part Data Hiding.
