Audio Steganography Using Least Significant Bit

Sudha Lakshmi N

Steganography is the art of hiding messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message. Audio signals are more challenging compared to the images or videos. Audio Steganography is the technology which uses to hide information in audio files. This project describes a high-capacity steganography algorithm for embedding data in the inactive frames of low bit rate audio streams encoded which is used extensively in Voice over Internet Protocol (VoIP). This study reveals that, contrary to existing thought, the inactive frames of VoIP streams are more suitable for data embedding than the active frames of the streams that is steganography in the inactive audio frames attains a larger data embedding capacity than that in the active audio frames under the same imperceptibility. A new algorithm for steganography is proposed in different parameters of the inactive frames. Consumption of time to encode and decode is reduced when compared to existing system.
